Securitron® BPSM-24-4 Self-Monitoring DC Power Supply, 120 VAC Input, 24 VDC Output, 4 A

When interfacing with a fire alarm system where the system's auxiliary relay cannot handle the full current potential of the power supply, or when monitoring power systems for AC failure or DC battery failure, the BPSM linear power supply is the right choice. The power supply status LED indicators and status output terminals combine with BPS features to offer the next stage of protection.
