Description
This serial power supply is a kind of high-precision linear dc power supply. It composed of two way regulated output and one-way fixed output. In addition, it can be acted both as constant voltage and constant current power supply. What’s more, its constant voltage and constant current can convert automatically. With high stability, high reliability and low noise, it can be used in many different areas.
Application:
1. Educational Laboratories
2. Electronic production line
3. communications industry
4. product research
5. All other areas need dc power supplies
Suitable for the laboratory, electronic, communication equipment maintenance, products line, scientific research and teaching units
Products related to auto/products, related to electron/ products related to the computer, research institutions, educational institutions can use it
Feature:
1. Two adjustable outputs and one 5V/3A fixed output
2. The two-way regulated power supply can be randomly in series, in parallel or independently according to requirements. And do not need external connection, just control by a switch
3. Have constant voltage and constant current operation mode. C.C and C.V convert automatically
4. Low Ripple and Noise
5. 4 groups of 3 digits LED display
6. Have current limitation protection
