Setup time	100 ms at rated DC input and full load.

Control, connections and protection

Pin assignment	Pin 1: +INPUT; pin 2: −INPUT (GND); pin 3: +OUT; pin 4: N/C; pin 5: −OUT; pin 6: CONTROL.
Remote ON/OFF control	CONTROL input is pin 6, referenced to pin 2 (−VIN). CMOS or open-collector TTL compatible. ON: +5.5 V DC minimum or open circuit. OFF: +2.5 V DC maximum or short CONTROL to pin 2.
Overload protection	Above 105% of rated output power; over-power limiting with automatic recovery after the fault is removed.
Overvoltage clamp	10.4–13.5 V.
Short-circuit protection	Automatic recovery after the fault is removed. Short-circuit duration must not exceed 60 seconds.

Operating conditions

Cooling and load derating	Free-air convection; horizontal installation. The curve shows 80% load at −25°C, 100% from −10°C through +60°C, and 75% at +70°C. Follow the curve between marked points; the operating range ends at +70°C.
Environment	Working temperature: −25 to +70°C with derating. Working humidity: 0%–95% RH maximum. Storage: −40 to +85°C, 0%–95% RH.
Temperature coefficient	±0.03%/°C over 0 to +60°C.
High-altitude derating	Above 2000 m, reduce the applicable ambient-temperature limit by 3.5°C per 1000 m for this fanless converter.
General measurement conditions	Unless specifically stated otherwise, parameters are measured at 12 V DC input, rated load and +25°C ambient.
Ripple measurement	20 MHz bandwidth; a 12-inch twisted-pair wire terminated with 0.1 µF and 47 µF capacitors connected in parallel.

Safety and EMC integration

Safety standards	UL62368-1 and EAC TP TC 004 approved. BS EN/EN62368-1 is identified as a design reference.
Input/output isolation	1000 V DC.
Isolation resistance	100 MΩ between input and output, measured at 500 V DC, +25°C and 70% RH.
EMC emission	Compliance with BS EN/EN55032 (CISPR32) Class B and EAC TP TC 020, subject to the stated component test arrangement and final-equipment verification.
EMC immunity	Compliance with BS EN/EN61000-4-2, -3, -4, -6 and -8; BS EN/EN55035, light-industry level; EAC TP TC 020.
EMC test arrangement	The manufacturer tested the converter as a component mounted on a 230 × 230 × 1 mm metal plate. Reconfirm EMC compliance in the final equipment; the test plate is not stated to be a supplied accessory.
Required input capacitor	Add a 220 µF / 100 V electrolytic capacitor with ESR <1 Ω to the input line for proper operation.
Suggested EMC input filter	The input filter drawing shows 80 µH inductive filtering and a polarized 680 µF capacitor across the converter input, on the converter side of the inductive elements. Select component ratings for the actual input range and verify the finished equipment.
