i-PRO MC-75-B100C4D8PE-4 LifeSafety Power Supply (75 W)
The MC-75-B100C4D8PE-4 is a 75 W LifeSafety Power FPO75-B100C4D8PE4M access-control supply for small-to-medium door counts. Sized below the 150 W class, it suits installations of a few doors with single-point strikes or compact maglocks, where the larger supply would be over-provisioned and waste rack/closet space.
Key Features
- 75 W LifeSafety Power FPO75-class access-control supply
- Selectable 12 VDC / 24 VDC output for compatible lock and reader hardware
- Battery-charging circuit for sealed lead-acid backup batteries
- Individually fused output channels for device-level protection
- Tamper and AC-fail outputs for panel monitoring
- Fire-alarm release input for life-safety unlock
- UL listings appropriate for access-control deployment
The 75 W class is a good match for small installations — single-door tenant suites, small offices, multi-tenant corridor entries, and back-of-house doors where the door count and current draw fit comfortably under the supply's capacity. Picking the right-sized supply matters: too small and the supply cannot ride out simultaneous actuation transients; too large and the buyer pays for capacity they will never use.
Verify worst-case simultaneous lock current draw, reader current, and accessory loads sum to no more than 80 percent of the supply's rating. Wire AC-fail and tamper to the panel for monitoring. Replace the battery on a 3-5 year schedule and label the install date inside the enclosure. For sites that may grow over time, consider stepping up to the 150 W class instead — the marginal cost is small and the additional capacity protects against future expansion without a supply replacement.
