MARS 50506 Transformer 250VA 240/480-120/240V

The MARS 50506 Transformer is a power conversion unit used to step down or adjust voltage levels for control circuits and auxiliary assemblies. It operate on a dual primary input of 240/480V and provides a selectable secondary output of 120/240V, supporting stable electrical supply to thermostat, relay, contactors and safety controls. By regulating incoming voltage in HVAC systems, it maintains consistent power distribution to sensitive control elements in heating and cooling equipment. This transformer is commonly used in air handling units, furnace controls and compressor control panels where reliable voltage adaptation is required for safe circuit operation.
