switching power supply for telecommunication use

switching power supply for telecommunication use
Product Detailed
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:

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.
