SKU CH-Z2FT-CVPEY MPN PRO42PSU120

Rack-mountable power supply for PRO4200 access control units, delivering 120 watts

  • Designed for PRO4200 access control systems
  • 120 W output powers connected devices reliably
  • Rack-mountable form factor fits standard enclosures
  • Honeywell engineering ensures consistent performance
  • New condition — ready for immediate deployment

Rack-Mountable Access Control Power Supply

The Honeywell PRO42PSU120 is a dedicated power supply built for the PRO4200 access control platform. It fits standard rack installations and delivers regulated output to the controller and attached peripherals. System integrators and security installers use it to provide reliable power in commercial access deployments.

Replaces an Aging or Failed Unit

When an existing PRO4200 supply shows voltage drift, audible noise or complete failure, this unit restores stable operation without rewiring the rack. The swap is worth it when downtime on doors or readers becomes unacceptable and a direct replacement keeps the current wiring and enclosure intact.

120 W Output with 42 V Regulation

The 120 W rating at 42 V handles the main controller, multiple reader ports and typical lock loads in a mid-size installation. Headroom remains for a few auxiliary devices, but large strike arrays or long cable runs with high inrush current will exceed the available capacity.
