Project Description
This serial single output switch power supply is a kind of DC regulated power supply with high efficiency and stability. It can be acted both as constant voltage as well as constant current dc power supply. For this serial power supply,it has perfect protection circuit, can be used in many areas.
Features:
1. Single phase, single output dc power supply
2. Constant voltage and constant current operation (C.C and C.V. automatic conversion)
3. Both current and voltage can be adjusted from 0 to rated value
4. 4 digits LED digital display
5. Built-in EMI filter (Anti-interference circuit)
6. Intelligent temperature control fan to help power supply cooling fast
Application:
Charge batteries, PCB board manufacturing industry/motors, LED products, and dc fans test/electrofishing, electrolyzation, electronic components aging/laboratory, Electronic equipment, automatic Test Equipment/All other occasions need to use DC Power Supply
