Programmable Dc Power Supplies

We are exporting, manufacturing and supplying Programmable DC Power Supplies in Shijiazhuang, Hebei, China has RS232 programmable interface and optional USB interface. The two working states, CV and CC, can be switched varying with the load. Series and independent working selection can be realized for the two channels. It is widely applied in national defense, institution, university and factory, especially in the areas of computer measuring and automatic control system as DC power supply.

FEATURES:
3 Channel outputs
Keypad input without potentiometer adjusting
Voltage and current output status are both displayed
Step output mode, Easy setting with step 10mV.
Software Calibration function
Short circuit protection function to guarantee the safety
CV/CC protection, over-voltage protection. Intelligent controlled fan
Standard RS-232, optional interface of USB
