DC/DC Power Converter, buy DC TO DC CONVERTER on China Suppliers Mobile

Product Details

Specifications

It use the PWM (pulse width modulation) technology with automatic current sharing function and N +1 backup function

Introduction:

The DC converter power supply of DD-series is the dedicated power supply that we design for the communications equitment, which is a DC-DC converter that converts the 24V input power supply to 48V output power supply to provide electricity for equipments.

The series use the PWM (pulse width modulation) technology with automatic current sharing function and N +1 backup function. When the power supply module failure, it can safely auto-exit and alarm, which ensure that the power supply system works normally.

Features:

1. Using the inside air-cooling methods, with lower noise

2. Strong protection function

3. High reliability

4. Maintain Simply, quickly and easily

5. With the normal instructions of input and output, and alarm function

6. EMC characteristics: Consistent with the standard EN55022 CLASS B & IEC61000-4 LEVEL 3
