| Kalvin:
Old thread, but here is the latest version of this design providing three separate isolated outputs using the inexpensive DPS3005 (or similar) power supply modules. - Universal DC-input from 9V to 36V, which allows using the power supply from a car battery, an inexpensive 19V PC battery charger or a 24 AC-to-DC converter. - Each channel has its own isolated DC-DC-module providing the isolated input voltage for the DSP3005 module. - Maximum power per channel limited by the DC-DC-module and/or DSP3005 power ratings. - Multiple channels can be connected in series or parallel without problems with the ground loops etc. - No problems with the earth leakage current. - Very small in size, easy to carry around in the lab or in the field. - Optional support for the USB or Bluetooth connection for controlling the DSP3005 module. - Optional support for the relay controlling the output enable/disable with an opto-coupler for a) an individual channel or b) multiple channels in parallel. - The DC-DC-modules used are CUI Inc. 30W, Vin: 9V - 36V, Vout: 15V 2A and 24V 1.25A. |
