It is widely used in power DC system, industrial control, communication, and battery charging equipment and for scientific research.
II. Features
It uses switch power technology. Input voltage range is broad.
Max. Output is 250V/15A, max. Power is 3750W.
The voltage stabilization value (when output current is less than setting current, output voltage is equal to setting voltage, the device is in voltage stabilization mode) and current stabilization value(when output is equal to setting value, output voltage is less than setting voltage, the device is in current stabilization mode) can be adjustable within 0-100% of max. Value.
With protection functions. It built-in temperature control heat dissipation fan. With over-heating automatic power off protection. With over-voltage, over-current and short circuit protection.
Digital display output voltage and current.
Easy operation.
