PSU-7 1-Rail Adjustable PSU
PSU-7 Module
The PSU-7 modules was designed as a single rail linear regulated supply that, using the HV version of the LM317, could be used to supply a 48V phantom power rail.

For light duty applications the device does not require a heatsink, however if the voltage differenial or supply current requirements are high then a heatsink will be required.
