Federal Signal Power Supplies provide nominal 12VDC or 24VDC power that is switch selectable. The PS250 and PS600 are designed for use as standby battery back–up during a power outage. Both power supplies operate from a 120VAC, 60Hz power source (240VAC available upon request).

The steel enclosure is designed to mount on a wall or substantial vertical surface (indoor only). A key lock is provided to discourage unauthorized access – simple lock installation is required.

The power supply sub–assembly, which recharges the batteries, includes solid–state circuitry that provides DC operating voltage to units in a SelecTone system, while maintaining a charge level on the batteries.

Both units can also be used as a primary 12V or 24V power source for other devices/systems.
