Information: 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 0-20.00A, step by 0.01A. This module has power-down stored function and can store 10 groups preset 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 overvoltage value, overcurrent value, over-power value, data set and LCD brightness. This module has many advantages, small size, advanced function, good visual effect, high operability, high-preci sion, being used independently, being inset into the device and been widely applied. Two version can select: Type A: DPS5020 No Communication VersionType B: DPS5020 Communication Version USB Board+bluetooth BoardType C: DPS5020 Communication + USB version Very important: 1.

1. DPS series are updated version. Panel is different. In DPS series, we change the M1/u2191and M2/u2193 into V/u2191and A/u2193. You can press those buttons Set the voltage and current fast. We add a new function u201cset default boot open or close outputinchsOthers are not changed. 2. All those power supply can charge the battery directly, don"t need external diode. When charging battery, don't connect battery polarity reversely , otherwise, power parts will bunt. Find the difference between DPSandDP see this video https://www.youtube.com/watch?v=ptt931rrXo8 3. DPpower supply and DPS power supply are all buck (step-down) converter. But DPH3205 and DPH5005 is buck-boost (step-down and step-up) converter. 4. DPS3005, DPS5005 DPS5015, DPS5020, DPH5005 and DPS8005 have communication version. You can connect PC and use upper computer.

This Produkt is able to make an old Powersupply in a Top new one with remote Control. The ripple could be better. I take a big Condensator in the Input circuit an the Ripple was lower on the Output. Easy to install and a very good Remote Software. In a scale from 1 to 10 its a 9 +
