Johnson Controls C450YNN-1 System 450 Power Module, 24 VAC [Refurbished]

The Johnson Controls C450YNN-1 is the System 450 Series power supply module. It steps 120 VAC or 240 VAC line power down to the 24 V supply required by a System 450 module assembly, so a control system can be built without a separate field-installed transformer.

System 450 is the Johnson Controls/PENN modular digital electronic control platform, designed to replace the older System 350 and System 27 ranges. A System 450 assembly can take its supply power either internally from a C450YNN power module plugged into the assembly, or externally from a 24 VAC (20 to 30 VAC) Class 2 source - but not both. The power module carries 120 VAC and 240 VAC supply input terminals and joins the rest of the assembly with the same plug-together connectors used by the control and expansion modules, so no field wiring is needed between modules. Like the other modules it is housed in a Lexan 950 enclosure and mounts on DIN rail or directly to a flat, even surface.

Typical applications are any System 450 control system installed where only line voltage is available at the panel - refrigeration rack control, condenser fan staging, boiler or chilled water staging, and clean room or greenhouse control assemblies that would otherwise need a separate 24 VAC transformer..
