Altronix T2RM7CK1D Rack-Mount Access Control Power Supply with Form C Relays

Overview

The Altronix T2RM7CK1D is a rack-mount power supply and relay module engineered for commercial access control and surveillance infrastructure. Designed to slot into the T2RM7F8SD pre-wired rack enclosure, this unit delivers 12VDC or 24VDC at 6A continuous — enough sustained output to power multiple door controllers, electrified hardware, or field devices without derating under load. If you're building or expanding a centralized power distribution rack for an enterprise access control system, the T2RM7CK1D is the core power module that anchors that infrastructure.

UL Listed and CE marked, the T2RM7CK1D draws 120VAC/60Hz at up to 4.5A input and converts to regulated DC output suitable for a wide range of access control peripherals. A 6.3A/250V input fuse protects upstream wiring and the transformer — a straightforward overcurrent safeguard that simplifies commissioning and AHJ inspections.

Key Features

• 6A Continuous DC Output at 12VDC or 24VDC: The selectable output voltage means you can match the supply to the specific door hardware on a given run — 12VDC for most electric strikes and mag-locks, 24VDC for higher-voltage locking hardware — without sourcing a separate supply per voltage tier.
• Form C Relay Outputs (28VAC or VDC @ 2.5A): Onboard Form C relays rated at 28VAC or VDC at 2.5A give you normally-open and normally-closed control contacts directly at the rack. This means door-strike switching or alarm integration can be wired to the module rather than run back to a distant panel — a real wiring economy on multi-door deployments.
• PTC-Protected Outputs at 2.5A: Positive temperature coefficient (PTC) resettable overcurrent protection on outputs eliminates the need to manually replace blown fuses on individual device runs. A shorted field device trips the PTC; once the fault clears, the output self-resets. This matters on large sites where tracking down a blown fuse per door can consume hours of tech time.
• 1A Unswitched Auxiliary Output: The auxiliary 1A output runs continuously, independent of relay state — purpose-built for powering controllers or readers that must stay live regardless of the relay's position. Wire your access controller here; the relay handles the locking hardware.
• UL Listed and CE Certified: UL Listing means this unit has been independently tested to recognized safety standards — relevant for installations in jurisdictions where AHJs require listed equipment, or wherever your security spec requires UL-compliant power sources. CE marking covers European conformity for cross-border or international deployments.
• 0°C to 49°C Operating Range: The specified operating temperature accommodates standard IT room and telecommunications closet environments. The 49°C upper limit is practical for equipment rooms without precision cooling — not a cold-storage or outdoor-rated unit, but solid for typical IDF closets and centralized head-end rooms.
• 123 BTU/Hr. Heat Dissipation: At 123 BTU/Hr., you'll need to account for this unit's thermal contribution in a populated rack. In a fully loaded multi-module enclosure, aggregate BTU output drives ventilation decisions — factor this number into your rack thermal budget before finalizing the enclosure layout.
• Lifetime Manufacturer Warranty: Altronix backs the T2RM7CK1D with a lifetime warranty — meaningful for infrastructure-grade power equipment that's expected to outlast the devices it powers by a significant margin.

Integration and Compatibility

The T2RM7CK1D is engineered to install directly into the Altronix T2RM7F8SD pre-wired rack enclosure, which handles the backplane interconnects and reduces field wiring labor substantially. The 19.0
