DC Power Supply - ESP
Product Introduction

 

Specially for industrial and laboratory equipment

ESP DC power supply is featured in conventional structure, reliable and stable. It’s equipped with fixed voltage and limited current device. LED indicator on Panel gives digital voltage and current, displaying clearly and simple in operation.

 

Feature:
   

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
