DC power supply

Description

Adjustable DC power supply.

Application range:

1. Factory product test aging: such as DC motor, DC fan, car DVD, car audio, resistance, capacitance and other products test aging.

2. Battery charging industry: it is used in the battery charging industry, providing constant current charging first and then converting to constant voltage trickle charging to prevent overcharge, protect the battery and effectively extend the service life of the battery.

3. Inverter Industry: it overcomes the stuck problem of linear power relay conversion, and has extremely fast response speed to meet the requirements of transient load changes.

4. LED manufacturing industry: LED testing, aging.

5. All other occasions requiring DC regulated power supply.

According to the output voltage and output current, the product can be divided into six models. The specific parameters of one of them are introduced below.

Qw-ms**5d product introduction

Product features:

1. Thickened steel plate case, beautiful and durable. Handle design, easy to carry.

2. The voltage and current are designed with coarse and fine adjustment to accurately adjust the output voltage value.

3. Automatic conversion of constant voltage and constant current can be used as constant voltage source or constant current source.

4. Perfect protection function: over voltage protection (OVP), short circuit protection (OCP), over temperature protection (OTP).

5. The circuit design is reasonable, the key parts are imported, and can be used with full load for *4 hours.
