Altronix MAXFIT55P32D 16-Output Access Power Controller Kit

The Altronix MAXFIT55P32D is a pre-assembled access power controller kit that consolidates two EFLOW102N power supplies, two PD16WCB 16-output distribution boards, and a BC750 enclosure into a single orderable unit — exactly what integrators need when wiring multi-door access control or large-scale surveillance deployments without sourcing every component separately. It accepts 120VAC/60Hz input and provides up to 10A total output at selectable 12VDC/24VDC or 24VAC/28VAC, with 16 individually fused outputs rated at up to 2A each via resettable PTC protection.

Overview

Centralizing power distribution for access control and access control systems is the right call on any multi-door installation — daisy-chaining wall-warts is a maintenance and troubleshooting nightmare. The MAXFIT55P32D packages the core Altronix power architecture into a single kit: dual EFLOW102N supplies for redundant or split-voltage configurations, dual PD16WCB distribution boards for 16 protected outputs per board (32 total across both boards), and the BC750 steel enclosure that houses everything in a clean, lockable panel. The 19-gauge steel enclosure ships with a cam lock and keys, and includes 3/4" and 1" conduit knockouts so you can plan your cable runs before the unit arrives on site.

Key Features

• 10A Total Output Capacity: With 10A available across the distribution outputs, the MAXFIT55P32D can comfortably power a mix of electric strikes, magnetic locks, and camera heads on the same panel — without routing separate circuits for each device class. Size your load budget carefully: 16 outputs at 2A max each gives you flexibility, but the 10A aggregate is the ceiling.
• Selectable Output Voltage (12VDC/24VDC or 24VAC/28VAC): The dual-voltage output options mean this kit isn't locked into one device ecosystem. 12VDC suits most IP cameras and electric strikes; 24VAC covers legacy access hardware and certain door controllers. Match the output to your field hardware before commissioning — switching voltage after installation is a panel-open job.
• 16 PTC-Protected Outputs at 2A Max Each: Resettable PTC (Polymeric Positive Temperature Coefficient) fuses on every output eliminate blown-fuse service calls. If a load shorts or spikes, the affected output limits current and self-resets once the fault clears — the other 15 outputs stay live. On a 32-door installation, this is the difference between a 2-minute reset and a half-day troubleshooting visit.
• Dual EFLOW102N Power Supplies: Two EFLOW102N modules included in the kit allow independent power sourcing for each PD16WCB board. Run them in tandem for full 10A capacity, or configure for split-voltage zones if your installation requires different output voltages across door groups.
• 1A Unswitched Auxiliary Output: The 1A auxiliary output stays live regardless of the main distribution state — useful for powering a door controller CPU, panel communication module, or alarm input that must remain energized even during a controlled shutdown of field devices.
• Over-Voltage, Short-Circuit, and Overload Protection: Triple-layer protection on the supply side means a field wiring fault won't cascade into supply damage. Over-voltage protection guards downstream devices; short-circuit and overload protection guard the supply itself. This is particularly relevant on large installations where a wiring error at one door shouldn't take down the entire panel.
• 19-Gauge Steel Enclosure with Cam Lock: The BC750 enclosure is 19-gauge steel — heavier than the sheet metal used in many OEM power boxes — with a cam lock keyed entry. Cam lock hardware is faster to service than standard screw-close panels and more tamper-resistant than push-latch enclosures. Keys and battery leads are included.
• 3/4" and 1" Conduit Knockouts: Pre-punched knockouts for both conduit sizes mean you won't need a step drill on install day. Standard EMT fits the 3/4" knockouts; rigid conduit or larger bundles use the 1" openings. Plan conduit entry points during rough-in — the enclosure layout rewards pre-planned runs.

Integration and Compatibility

The MAXFIT55P32D is designed for integration with access control panels and multi-camera IP surveillance systems requiring centralized, protected 12VDC, 24VDC, or 24VAC/28VAC power. The selectable output voltage makes it compatible with a wide range of electric strikes, magnetic locks, card readers, and IP cameras. Battery leads are included for connecting a backup battery (battery not included in kit) — an important detail for installations requiring code-compliant power backup under NFPA 72 or local AHJ requirements. Consult your surveillance power supply selection guide to verify load calculations before specifying this unit on larger deployments.

Frequently Asked Questions

Q: What output voltages does the MAXFIT55P32D support?

A: The MAXFIT55P32D supports selectable 12VDC/24VDC or 24VAC/28VAC outputs, making it compatible with a broad range of access control hardware and IP cameras.

Q: How many outputs does the MAXFIT55P32D provide and what is the per-output current limit?

A: It includes two PD16WCB distribution boards, each with 16 outputs — 32 outputs total. Each output is protected by a resettable PTC fuse rated at up to 2A maximum, with an aggregate system output of 10A.

Q: Is a backup battery included with the MAXFIT55P32D kit?

A: No. The kit includes battery leads for connecting an external backup battery, but the battery itself is not part of the MAXFIT55P32D bundle. Select a compatible sealed lead-acid battery based on your standby runtime requirements.

Q: What enclosure does the MAXFIT55P32D use and how is it secured?

A: The kit uses the Altronix BC750 enclosure, constructed from 19-gauge steel. It ships with a cam lock and two keys for tamper-resistant access.

Q: What conduit sizes are supported by the BC750 enclosure in the MAXFIT55P32D kit?

A: The BC750 enclosure includes pre-punched knockouts for both 3/4" and 1" conduit, accommodating standard EMT and rigid conduit runs without additional field drilling.

Q: What protection features are built into the MAXFIT55P32D?

A: The MAXFIT55P32D includes over-voltage, short-circuit, and overload protection at the supply level, plus per-output resettable PTC protection on all 16 outputs of each PD16WCB board.
