Mars M50364 Foot Mount Transformer 40VA 120/208/240V to 24V

Product Description

The MARS M50364 is a foot-mount control transformer rated at 40 VA, designed to step down line voltage to the 24-volt signal voltage required by low-voltage control circuits in HVAC systems. It accepts primary voltages of 120, 208, or 240 volts and delivers a steady 24-volt secondary output, making it adaptable to a range of commercial and residential power supplies. This transformer provides reliable isolation between the line-voltage side and the low-voltage control circuit. It is installed by licensed HVAC technicians during new equipment installation or as a direct replacement when an existing transformer has failed or is undersized for the connected control load.

This transformer is suited for low-voltage control applications in gas furnaces, air handlers, heat pumps, rooftop units, and other HVAC equipment that relies on a 24-volt control circuit. The foot-mount configuration allows for secure panel or chassis mounting inside the equipment cabinet. It is appropriate for both residential and light commercial installations where a multi-tap primary transformer is needed to match available supply voltage. When replacing a failed transformer, technicians should verify total connected VA load from thermostats, zone controls, and accessories does not exceed 40 VA.

Key Features

• 40 VA rating supports standard residential and light commercial low-voltage control loads
• Multi-tap primary accepts 120, 208, or 240 volt supply voltage
• 24-volt secondary output compatible with standard HVAC low-voltage control circuits
• Foot-mount design allows secure chassis or panel mounting inside equipment cabinets
• Provides line-to-control-circuit isolation for protection of sensitive control components

Compatibility

Designed as an OEM-style replacement control transformer for residential and light commercial HVAC equipment requiring a 40 VA, 24-volt secondary, foot-mount transformer with a multi-tap 120/208/240-volt primary.

Installation Notes

Installation should be performed by a qualified HVAC technician. Disconnect and lock out all power to the equipment before removing or installing the transformer. Confirm the primary tap selection matches the available supply voltage before energizing, and verify that the total VA demand of all connected low-voltage devices does not exceed the 40 VA rating to prevent overheating or nuisance failures. All wiring should comply with applicable NEC requirements for control circuit wiring.
