i-PRO MC-75-B100C4D8PE LifeSafety Power Supply (75 W)
The MC-75-B100C4D8PE is a 75 W LifeSafety Power FPO75-class access-control supply for small-to-medium door counts. It provides clean, fused, battery-backed power for a handful of doors with single-point strikes or compact maglocks. Right-sized for installations where the larger 150 W class is over-provisioned.
Key Features
- 75 W LifeSafety Power FPO75-class access-control supply
- Selectable 12 VDC / 24 VDC output
- 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 the right pick for small installations where larger capacity would simply waste rack and closet space. Multi-tenant corridor entries, tenant suites, small offices, and back-of-house doors all map cleanly to the FPO75. The LifeSafety topology absorbs the inrush characteristics of access-control loads, so the supply remains stable even when multiple doors actuate at the same time.
Size based on worst-case simultaneous lock current plus reader and accessory loads, then add 20 percent headroom. Wire AC-fail and tamper to the panel for monitoring. Configure fire-alarm release per local code. Replace the battery on a 3-5 year schedule. Document the install date on a label inside the enclosure for future reference. For sites likely to grow, consider stepping up to the 150 W class to protect against future expansion.
