Specifications

It use the most advanced PWM technology and the most stable and reliable circuit topology

Introduction:

This series of high-frequency switching power supply are designed for a variety of communications electronics equipment, such as program-controlled switches, microwave equipment, optical fiber communication equipment etc. which are high efficiency, high performance, high stability, high reliability, and which use the most advanced PWM technology and the most stable and reliable circuit topology.

The series are small size, light weight, high efficiency, wide operating temperature range, strong anti-jamming capability, fast dynamic response, high stability, smal noise ripple, and with strong protection features, which apply to CNC machine tools, data-processing and other equipment, and which can be used as charging and discharging equipment for battery.

Features:

1. High precision regulators

2. Fast dynamic response

3. Low output noise

4. Strong anti-interference ability

5. Wide operating temperature range

6. Strong protection function

7. With N +1 module composite structure

MTBF	≥100000 Hrs.
Cooling Method	Forced air-cooled: 65CFM (Internal DC fan), when the temperature of radiator is over 85, the output begins to derate; when the temperature of radiator is up to 95, the output will derate to 60%; when the the temperature of radiator is over 95, the device will close.
Protection	Input Overload	Dc<130±5V, device will close automatically
	Input Underload	Dc>300±5V, device will close automatically
	Output Overload	Vdc≥60±1V, device will alarm to close, which need to manually re-start after the fault removed
	Output Short-circuit	Retraction limiting, recover automatically after the fault removed.
	Over temperature	When the temperature of the case is (85±5), the rectifier begins to derate; when the temperature is up to (95±5), the output will derate to 60%; when the temperature is over (95±5), the device will close and alarm.
