Model and electrical specifications

Model and configuration	XTR-240P-12LA; XTR-240 series; LA terminal option (tool-free lever-actuated terminals). P denotes the by-request parallel version. Single adjustable DC output and 48 mm slim casing width. Conformal PCB coating provides basic moisture and dust protection.
Rated continuous output	12 V DC, 15 A, 180 W. Load-current range 0–15 A. Apply all input, temperature and installation limits; peak output is separate.
Output voltage adjustment	12–15 V DC using the front Vo Adj. control. Remain within the selected current and power limits.
AC and DC input	Three-phase 320–600 V AC or 450–800 V DC; AC frequency 47–63 Hz. Two-phase operation is allowed only with the specified input and temperature derating. The feature page additionally permits an occasional 600–700 V AC surge for 1 second; this is not a continuous input rating.
Two-phase input connection	Connect L1, L3 and FG, or L2, L3 and FG, as shown in the XTR installation manual. Preserve protective earth and use the selected two-phase load curve; two-phase operation is not bidirectional power conversion.
Typical efficiency	88.7% for this selected model. The XTR-240 series maximum is 93.5%; it does not replace the individual model’s typical value.
No-load power	No-load power consumption 2.5 W typical at 400 V AC. The feature summary describes below 2.5 W; retain the detailed table’s typical test reference.
Input current	0.69 A at 400 V AC; 0.6 A at 500 V AC; typical.
Cold-start inrush current	10 A typical at 400 V AC. The series feature describes inrush below 10 A; use the detailed typical value and its stated test voltage for design.
Leakage current	<2 mA at 530 V AC.
Power factor	Typical PF ≥0.53 at 400 V AC and ≥0.52 at 500 V AC, at full load.
Ripple and noise	100 mVp-p maximum, measured at 20 MHz bandwidth using a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors in parallel.
Regulation and tolerance	Voltage tolerance ±1.0%, including set-up tolerance, line regulation and load regulation. Line regulation ±0.5%; load regulation ±1.0%.
Setup and rise time	2000 ms / 60 ms at 400 V AC; 1500 ms / 60 ms at 500 V AC (setup / rise), at full load.
Hold-up time	20 ms at 400 V AC; 40 ms at 500 V AC; typical, at full load.
Measurement conditions	Unless separately stated, parameters are measured at 400 V AC input, rated load and 25°C ambient temperature.
Block-diagram switching frequencies	Passive PFC; PWM 60 kHz.

Peak output and load derating

Peak output	22.5 A / 270 W for up to 5 seconds in the specification table. The series peak capability is 150%; it remains subject to the input, ambient-temperature, duty-cycle and average-power limits below.
Peak timing and average power	Simultaneously satisfy t ≤5 s, duty cycle t/T × 100% ≤35%, and P_av = [P_peak × t + P_non-peak × (T − t)] / T ≤ rated output power. The peak-load curve can require a lower duty cycle; 35% is not available at every peak level.
Peak-load curve	For three-phase 320–600 V AC, the peak curve permits 35% duty through 110% load and falls to 10% duty at 150% load. The 12 V graph scale reaches 270 W; the 24 / 36 / 48 V scale reaches 360 W. Follow the plotted line and all simultaneous limits.
Published peak-cycle example	The XTR-240-24 example at 400 V AC uses 240 W average, 360 W peak, t = 5 s and 10% duty. It requires T ≥50 s and non-peak power ≤226 W. This example does not remove the selected model’s own rating and curve conditions.
Continuous ambient-temperature curve	Vertical, three-phase operation: at 320–380 V AC, continuous load is 80% at −40°C and 100% from −30°C to +60°C; at 380–600 V AC, it is 100% from −40°C to +60°C. Above +60°C the continuous line falls to 30% at +85°C. Follow the source lines between the marked points and apply input derating at the same time.
Peak ambient-temperature curve	The three-phase peak ceiling is 150% from 0°C to +60°C, falling to 30% at +85°C. Below 0°C, do not infer a peak allowance from the continuous-load line; peak timing, duty and average-power limits still apply.
Input-voltage load curve	At 60 Hz: Three-phase: 100% load from 320 to 600 V AC. Two-phase: 70% at 320 V AC, 80% at 340 V AC and 100% from 380 to 600 V AC. Follow the plotted line between points; the full input rating alone does not mean full two-phase output.
Two-phase cold-start condition	Two-phase operation is shown for −30°C to +85°C. With ambient temperature from −30°C to −10°C and input from 320 to 380 V AC, cold starting may enter hiccup protection for approximately 5–10 seconds. This is a combined low-temperature and low-input condition. For vertical two-phase operation, the continuous-temperature load curve allows 100% from −30°C to +60°C and falls to 30% at +85°C. Follow the plotted line between the marked points and apply the two-phase input-voltage derating simultaneously.

Protection, controls and current sharing

Overload and short-circuit response	105–150% of rated output power for more than 5 seconds: constant-current limiting at rated output current, without shutdown while output voltage is 30–100% of rated voltage. The series lists short-circuit protection; the detailed protection table states the constant-current condition above.
Overvoltage protection	15–18 V; hiccup mode with automatic recovery after the fault is removed.
Overtemperature protection	Output shutdown or hiccup mode with automatic recovery after the temperature falls.
DC OK relay	Control connector B pins 1 and 2: contacts close when the supply is ON / DC OK and open when OFF / DC fail. Maximum resistive contact ratings are 30 V DC / 1 A and 30 V AC / 0.5 A. These are relay-contact ratings, not a powered output.
Parallel current sharing	Up to four units may be connected in parallel. Match their output voltages to a difference below 0.2 V. Join all P+ pins (B pin 3) together and all P− pins (B pin 4) together using twisted pairs; P− is internally connected to −Vo. Keep power wiring short and use a large conductor diameter. Total output current must not exceed I_rated × n × 0.9.
Parallel minimum load and capacity	Minimum load must be greater than 5% × I_rated × n, where n is the number of paralleled units. The series feature describes up to 960 W (3+1); this is a configuration reference, not guaranteed usable N+1 load power. Determine capacity from the selected unit rating, 0.9 current factor, derating and required redundancy.
Optional inverse-voltage protection	The ORing FET is separately available by request; the P parallel code alone does not confirm this option. With the specified ORing option, the maximum allowable reverse voltage for the 12 V output is <16 V. The source describes protection against back EMF during motor or inductive-load deceleration; confirm the supplied option.

Unit weight and packing	990 g per unit as the catalog PACKING reference; carton 12 units / 12.9 kg / 1.16 CUFT. This is the catalog per-unit packing reference, not a separately measured net weight.

Installation and system verification

Installation safety and protective earth	Installation and fault examination are for qualified personnel. Disconnect the system from supply voltage and prevent accidental reconnection before installation, maintenance or modification. Connect FG / PE to protective earth. Do not join the primary and secondary sides or remove the case yourself. Keep foreign objects and dripping liquids out; avoid touching hot surfaces during operation or shortly after disconnection. Use copper connectors and wires in a dry, well-ventilated pollution-degree-2 enclosure. The system assembler is responsible for complete-system safety. Use outside the manufacturer’s specified manner may impair the protection provided by the device.
Vertical DIN rail installation	Mount vertically with input terminals below and output terminals above on TS35/7.5 or TS35/15 rail. Tilt the unit slightly backwards, engage the top rail edge, slide it down to the stop, press the bottom to lock and gently check the latch. Upside-down, horizontal and table-top orientations are not permitted by the installation manual.
Ventilation and thermal layout	Allow at least 40 mm above, 20 mm below and 5 mm on each side for natural air cooling. Keep 15 mm from an adjacent heat source; this also meets the manual’s 10–15 mm instruction. Keep ventilation openings clear. Apply the selected model’s input and ambient-temperature curves together; the general operating-temperature range does not promise full load. Do not install near water, high moisture or fire sources.
Copper wiring and current distribution	Use copper wire with insulation rated at least 80°C, such as UL1007 or UL1015. The manual’s UL1015 recommendations pair AWG 18 / 16 / 14 / 12 / 10 with equipment currents 7 / 10 / 15 / 20 / 37 A and cross-sections 0.8 / 1.3 / 2.1 / 3.3 / 5.5 mm². These are recommendations, not exact AWG conversions or permission to exceed this model’s terminal capacity. When five or more wires are connected, reduce each recommended wire current to 80%. Insert every strand and securely fix the connection; connect all output contacts to distribute current.
Terminal preparation	Follow the selected main-datasheet connector capacities and stripping lengths; the manual’s generic 5 mm example does not replace the model-specific power and signal values. Blank types use screw terminals, LA types use tool-free lever-actuated terminals and PI types use push-in terminals. For LA, open the lever, insert the wire and close it; for PI, insert the wire. For Blank input / output screw terminals use 5.8 kgf·cm (5 lb-in); a 3 mm slotted screwdriver is recommended. Use the separate DC and AC DC OK contact ratings stated in this listing rather than the manual’s abbreviated 30 V / 1 A summary.
Hazardous-location installation limits	For the documented Class I, Division 2, Groups A, B, C and D use, install this open-type device in an enclosure suitable for the environment and accessible only with a tool. The manual specifies −30°C to +60°C, temperature code T4 and altitude up to 2000 m (or 80 kPa / 0.8 bar) for hazardous locations. The broader general temperature and altitude limits do not extend this hazardous-location rating. Otherwise use only in non-hazardous locations.
Installation-manual document boundaries	The installation manual dated 2026.08.13 gives nominal three-phase 380–500 V AC, 50/60 Hz references; the selected main datasheet specifies the operating range and its own current test conditions. Use those model-specific figures, terminal dimensions and standard-specific overvoltage-category limits. The manual’s generalized OVC III statement does not expand the main certification scope. Any fuse service requires the same type and rating and qualified personnel; no separate fuse ordering code is specified here.
Complete-system EMC verification	Verify EMC with the supply installed in the finished equipment and connected to a representative load. Wiring, assembly and the application affect the result. Retain the selected model’s EMC conditions; component test results and this EMI guidance do not certify the complete equipment.
