Features :

* Adopt Silicone transistor or SCR type-
Transistor: high stable rate, fast response, low ripple and ultra low noise
SCR type : highly stable control circuit allowing long time continuous full load output
* All digital display of output voltage and current- High precision and high resolution 3 and 1/2 LED display of voltage and current
* Fixed voltage and limited current structure: Allowing voltage has more accurate output and steadier current
* Overload, short circuit, reverse phase and abnormal – 4 protections- Used fast no fuse breaker with functions of abnormal and overload tripping, and internal reverse phase protection circuit and short circuit cutting circuit
* Output resolution- With high precision 10 turns adjusting knob allowing precisely adjusting to needed voltage
