The ALTRONIX CORP TM400K2 is an access control power supply designed to provide reliable, fused power distribution for door control and security access applications. Rated at 4 amps with 4 individually fused outputs, this unit operates on 115 volts AC and is built to support 2- to 3-door mercury-compatible access control systems. It delivers stable, protected power to downstream devices such as electric strikes, magnetic locks, and access control panels. Licensed low-voltage and access control technicians typically install this unit during new system builds or panel upgrades where fused output protection is required.
The TM400K2 is suited for commercial and light-industrial access control installations where multiple door controllers or locking devices must be powered from a single, centralized supply. The 4 fused outputs allow independent circuit protection for each connected device, reducing the risk of a single fault taking down an entire access system. This unit fits into 2- to 3-door mercury relay-based access configurations as a primary power source.
Designed as an OEM-style power supply for 2- to 3-door mercury relay-based access control systems requiring a 4 amp, 4 fused output, 115 volt power source.
Installation should be performed by a licensed low-voltage or access control technician in accordance with applicable NEC requirements for Class 2 or limited-energy power supplies. Disconnect and lock out all AC input power before making any wiring connections to the unit or to downstream devices. Verify that the total load across all fused outputs does not exceed the 4 amp rating of the supply. Each fused output should be sized appropriately for the connected device to ensure proper overcurrent protection.
