Lifesafety Power FPO75-B100C4E1M Dual-Output Power Supply
Overview
The FPO75-B100C4E1M is a 75W redundant power supply with dual independent outputs—2A @ 12VDC and 2A @ 24VDC—designed to power access control systems, door locks, and distributed IP endpoints in installations where split-voltage distribution is required. The four fused lock outputs allow independent circuit protection for each load, reducing nuisance breaker trips and simplifying troubleshooting when multiple 12V and 24V devices share the same enclosure.
Compatibility
This unit operates in the Lifesafety Power Mercury dual-output series and integrates with standard access control panel installations that require both 12VDC and 24VDC supplies. The E1M industrial-grade enclosure (14H × 12W × 4.5D inches) fits standard wall-mount and rack-install configurations typical of security integrations. Check lock voltage requirements against your specific reader, maglock, and control board specifications before commissioning—voltage mismatches will disable access control.
Installation Notes
This unit is backordered as of the current sourcing cycle. Confirm lead time with your supplier before scheduling integration. Verify input AC voltage availability at the deployment site; the supply requires standard 110–240VAC input. Fused outputs require field setup of lock-load assignments—plan circuit documentation and labeling per your project's cable management standard. Ensure adequate airflow around the E1M enclosure for thermal dissipation during continuous operation.
Power Distribution Decision
Dual-output supplies eliminate the need for separate transformers when 12V and 24V devices must coexist. The 2A per rail ceiling is adequate for low-draw scenarios (e.g., solenoid-only door locks, wireless readers); high-current loads (magnetic locks + strike + sensor + auxiliary relay) may require load calculation and possible secondary supply staging. Fused outputs protect the supply from short-circuit cascade failures—essential in unattended outdoor or warehouse automation environments.
