Edwards 3-BBC/M Booster Power Supply

The Edwards 3-BBC/M is a booster power supply and battery charger designed for Edwards EST3 fire alarm and life safety systems. It provides additional regulated and filtered power to the system rail while also supporting battery charging. The unit operates from a 120 VAC, 50/60 Hz input and provides 24 VDC nominal output at up to 7 amps. It includes two independent, power-limited auxiliary outputs rated at 3.5 amps each and supports one user interface module through its local rail module. The 3-BBC/M uses a heat sink assembly and monitor module configuration for installation within an EST3 chassis or wallbox. It can be combined with other power supplies for increased system capacity and supports battery sets up to 65 Ah. The model is discontinued and was replaced by the Edwards 4-PPS/M.
