- HT3323/HT3325 is a new generation DC stable power supply we launched, which can be program controlled. It has a USB program control interface and can output arbitrary voltage or current value; uses LED to display the working state of power; uses large scale intergrated circuit, supplies 3 circuits voltage output, voltage-stabilization values and current-stabilization values of circuit 1 and circuit 2 can be changed step by step, the two working states of steady voltage and steady current can be changed automatically with the change of load.The output of circuit 1 and circuit 2 can be in series, in parallel and work independently. The third circuit supplies the optional 4 kinds of output votage,1.8V、2.5V、3.3V、5V,and supplies overload protection.
Main features:
- 3-circuit high precision power independent controllable output:
- 32V/5A(32V/3A) these 2 circuits can be adjusted arbitrarily,1 circuit can be switched to 1.8V/2.5V/3.3V/5V/3A
- 5-bit voltage and 4-bit current display, the minimum resolution is 10mV,1mA
- 3 kinds of output mode:independent,series and parallel connection,support timing output and SCPI remote command
- All digital control,low drift
- Nixie tube to display voltage,current and power
- Memory replay function
- Constant voltage and constant current automatic switching
- 3 kinds of output:independent,series and parallel modes,increase the range of output power
- Digital knob adjustment;can coarse control,fine control;easy to set,intuition output
- Fan speed control
- USB interface,5V1AUSB charge and output interface
- Support timing output function,can achieve 10 sets of timing settings and output control
- 5 groups of system parameters save/call inside, support data storage space expansion
