Description

DETN01N-15N — 1W isolated dual-output DC/DC converter

MEAN WELL DETN01N-15N is an isolated, unregulated 1 W DC/DC converter in an SMD package with an industry-standard pinout. It accepts 21.6–26.4 V DC input (24 V nominal) and provides dual outputs of ±15 V DC relative to Common, with 3.4–34 mA on each rail. Observe the stated minimum load, regulation and cooling conditions.

Model selection and output

Complete model / series	DETN01N-15N / DETN01-N. Input code N: 24 V nominal; output code 15: dual ±15 V. N identifies the new series.
Conversion and rated power	1 W rated total across both rails. Rounded current values do not increase the rated power; observe the current window and thermal limits.
Output voltage and current	±15 V DC relative to Common; 3.4–34 mA on each rail. Both rails operate relative to Common and share the total rated power. The lower current value is the specified minimum load.
Efficiency	82% typical; at normal input, rated load, 25°C and 70% RH.
Series efficiency reference	The DETN01-N feature page states efficiency up to 83%; use this model's typical efficiency above for selection.
Maximum capacitive load	100 µF on each output rail.
Voltage accuracy	±5.0%.
Ripple and noise	100 mVp-p. Measured at 20 MHz bandwidth using a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors.
Line regulation	1.2% for 1% input variation; measured from low line to high line at rated load.
Load regulation	±8%; measured from 10% to 100% rated load.
Switching frequency	90 kHz typical.
Specification conditions	24 V DC normal input, rated load, 25°C and 70% RH, unless otherwise specified.

Input, protection and isolation

Input voltage	24 V DC nominal, ±10%; operating range 21.6–26.4 V DC.
Input current	No load: 11 mA; full load: 55 mA. The general specification conditions apply.
Input filter	Internal capacitor.
Recommended input fuse	150 mA slow-blow fuse recommended.
Internal power dissipation	500 mW.
Short-circuit protection	0.5 second maximum; do not rely on continuous short-circuit operation.
Input/output withstand voltage	3 kV DC between input and output.
Isolation resistance	10 GΩ between input and output; at 500 V DC, 25°C and 70% RH.
Isolation capacitance	75 pF typical.

Environment and reliability

Operating temperature	−40 to +100°C, subject to the model-specific cooling and derating curve.
Case temperature	+100°C maximum.
Cooling and derating	PDF page 49: 100% load from −40 to +85°C under natural convection. For the indicated full-load region above +85°C up to +100°C, the graph specifies forced-air convection at 300 LFM. The case-temperature maximum still applies.
Working humidity	20–90% RH, non-condensing.
Storage temperature and humidity	−55 to +125°C; 10–95% RH, non-condensing.
Temperature coefficient	0.03%/°C over 0–85°C.
Vibration	10–500 Hz, 2 G; 10 minutes per cycle, 60 minutes along each of the X, Y and Z axes.
MTBF	1,045,000 hours minimum, MIL-HDBK-217F at 25°C. This reliability figure is not a service-life or warranty duration.
Manufacturer warranty	3 years, as stated in the datasheet.
Design and applications	The manufacturer describes the series as low cost. Applications include telecom/datacom systems, wireless networks, industrial control, instruments, analyzers, detectors, data switches and distributed power architectures.

Safety and EMC integration

Safety standards	EAC TP TC 020/2011 approved.
EMC emission	BS EN/EN55032 (CISPR32): conducted and radiated Class A/B with the external components on PDF page 50.
EMC immunity	BS EN/EN61000-4-2: ±8 kV air and ±6 kV contact, criterion B; -4-3: 3 V/m, criterion A; -4-4: 1 kV at power, criterion B; -4-5: 0.5 kV line-to-line, criterion B; -4-6: 3 Vrms, criterion A; -4-8: 1 A/m, criterion A.
Immunity input capacitor	When the module must meet BS EN/EN61000-4-4 and -4-5, an external input filter capacitor is required. The datasheet gives Power Mate's recommendation of 470 µF / 100 V for that condition.
EMC circuit connections	PDF page 50: L1 is in series with the positive input; C1 is connected across the input before L1. A 470 pF / 4 kV DC capacitor connects the module-side +Vin node after L1 to output Common.
Class A external components	For DETN01N-xxN: L1 47 µH; C1 4.7 µF, with the common 470 pF / 4 kV DC coupling capacitor shown in the circuit.
Class B external components	For DETN01N-xxN: L1 100 µH; C1 10 µF, with the common 470 pF / 4 kV DC coupling capacitor shown in the circuit.

Mechanical details and PCB assembly

Construction	SMD package with industry-standard pinout; non-conductive black plastic case rated UL 94V-0.
Dimensions	15.24 × 10.9 × 7.1 mm (L × W × H), as specified.
Pin assignment	Pin 1 −Vin; pin 2 +Vin; pin 5 Common; pin 6 −Vout; pin 8 +Vout; pins 3, 7, 10, 11 and 12 N.C. Observe the top/bottom view orientation on PDF page 49.
Pin and drawing geometry	PDF page 49: 2.54 mm pin pitch, shown as 2.54 × 5; 11.1 mm lead span and 8.5 mm underside width. The side drawing marks a local vertical reference of 8.7 mm. The drawing also marks 0.25 mm at the lead foot. Its 8.7 mm local vertical annotation differs from the 7.1 mm specified overall height; confirm the manufacturer drawing before mechanical integration rather than treating 8.7 mm as the overall height.
Pin dimensions and tolerances	The general note specifies 0.50 × 0.30 mm pins, with ±0.07 mm pin tolerance. General drawing tolerances: x.x ±0.5 mm and x.xx ±0.25 mm.
PCB land pattern	Top-view grid on PDF page 49: 2.54 mm per grid; pads 1.20 × 1.80 mm; the drawing marks 12.00 mm across the pad rows. Match the numbered pads to the specified pin assignment.
Soldering temperature	At 1.5 mm from the case, 240°C maximum for 1–10 seconds.
Reflow soldering	The curve on PDF page 49 applies only to hot-air reflow soldering: peak 240°C for 10 seconds maximum; time above 220°C is 60 seconds maximum.

Standard tube packing	33 pieces per tube; 36 tubes and 1,188 pieces per carton. Tube gross weight 0.063 kg; carton gross weight 2.7 kg. These are standard packing references, not the quantity supplied with an individual order.

Optional output versions	The series lists optional ±3.3 V output versions: DETN01L-03N, DETN01M-03N and DETN01N-03N. Confirm their model-specific current and other ratings with MEAN WELL; this listing retains the output stated above.

Installation and system verification

Complete-system EMC verification	Verify EMC with the converter installed in the final equipment and connected to a representative load. Wiring, assembly and the application affect the result. Follow the model's specified EMC conditions and any required external components; the linked EMI testing guidance does not certify the finished equipment.
