DS3820PSLA is a power supply module under the mark IV series developed by General Electric. Power supplies convert incoming alternating current (AC) power into usable direct current (DC) power, allowing the system to be properly powered. It is also intended to condition the output so that it is free of problems such as spikes and noise, as well as to protect other components. WOC offers the DS3820PSLA as a reconditioned unit that has been thoroughly tested by our in-house technicians.
