• The constant voltage and constant current programmable control power supply module put the collection of analog integration and digital control functions in one.
• Its adjustable output voltage range is 0-50.00V, step by 0.01V. Its adjustable output current range is 0-3.000A, step by 0.001A This module has power-down stored function and can store 10 groups present value. And it also has the function of extracting quickly two groups stored value. Compared with the traditional analog power supply, it is more convenient to quickly extract the voltage or current required.
• LCD display on the module has the function digital voltmeter and ammeter. You can view the preset voltage, input voltage, output voltage, the preset current, output current, output power, etc. on the output state remind area, you can see that output opens or not, the state of constant voltage and constant current output is normal or not, the key is locked or not, and the current data groups that is being used.
• On the setting data interface, you can adjust over-voltage value, over-current value, over-power value, data set and LCD brightness This module has an intelligent long-life ball bearing fan When the output current is more than 0.5A, the fan will start working automatically to help product cooling to ensure output big power.
• This module has many advantages, small size, advanced function, good visual effect, high operability, high-precision, being used independently, being inset nto the device and been widely applied

The constant voltage and constant current programmable control power supply module put the collection of analog integration and digital control functions in one.JSN-ETN
