DP20V2A Power Supply Module CNC Programmable Constant Voltage Current
Here is a very good project from Thorsten Singer， he made this Battery Powered PSU (0-20V， 0-2A) (BPPSU) with case， you can see the details from here: http:\/\/www.instructables.com\/id\/Battery-Powered-PSU-0-20V-0-2A-BPPSU\/?ALLSTEPS
Product Information:
The constant voltage and constant current programmable control power supply module is cabinet and delicate， and it put the collection of analog integration and digital control functions in one.Its adjustable output voltage range is 0-20.0V， step by 0.1V.Its adjustable output current range is 0-2.00A， step by 0.01A.Boot voltages can be stored freely and the model has two groups of quick storage voltage.Compared with the traditional analog power supply， it is more convenient to quickly extract the voltage or current required.LCD display on the model has the function digital voltmeter and ammeter.You can view the preset voltage， input voltage， output voltage， the preset current， output current， output power and LCD brightness.
Technical parameters:
Weight: 59g\/pieceDimension: 79 x 42 x 26mm (L x W x H)Open size: 71 x 39mmInput positive: IN+Input negative: IN-Output current: 0-2.00AOutput power: Maximum 40WOutput positive: OUT+Output negative: OUT-Ripple frequency: About 330 KHzInput voltage range: 4.5-23V(23V is the limiting highest voltage. When you use it， make sure input voltage below 23V)Output voltage range: 0V-20.0V (In step down voltage mode， input voltage must be higher than 3V)， the control button can fast draw up 2 sets data.Ripple peak to peak value: 50mv (typical value)
