DCS-1
125VDC Auxiliary Power Supply

The DCS-1 Auxiliary Power Supply makes it possible to power virtually any SSI relay directly off of 125VDC station power. The DCS-1 power uses a switching power supply technology to efficiently power most standard SSI relays eliminating the need for an inverter. Because of the small size of the DCS-1, it replaces the power transformer on the host SSI relay and does not require any additional wiring or mounting space. A +12VDC output of the DCS-1 supplies the relay’s power supply requirements as well as providing a wetting voltage to the meter.

The DCS-1 must be ordered as a factory-installed option by adding an “-SP2” suffix on the end of the product’s part number. LS-Series relays are not available with the DCS-1 option.
