Hartland Controls tp-75va-multi Transformer 75VA Multi-tap

Product Description

The HARTLAND CONTROLS tp-75va-multi is a multi-tap control transformer rated at 75 VA, designed to step down line voltage to 24 volts for low-voltage control circuits in HVAC systems. It accepts multiple primary voltages — 120, 208, 240, and 480 volts — making it adaptable across a wide range of commercial and residential equipment without stocking multiple SKUs. The secondary output is a standard 24 volts, which powers thermostats, control boards, and relay coils. Wire leads and a quick-connect termination style are included for straightforward field installation. Licensed HVAC technicians are the primary installers of this component.

This transformer fits into control circuit applications in air conditioning, heat pump, gas furnace, and electric heating systems where a reliable 24-volt power supply is required. The multi-tap primary is particularly useful in light commercial settings where supply voltage may be 208 or 480 volts rather than the standard residential 120 or 240 volts. It serves as a direct replacement in panel-mounted or chassis-mounted positions wherever a 75 VA, 24-volt secondary transformer is specified.

Key Features

• Multi-tap primary accepts 120, 208, 240, and 480 volts for broad system compatibility
• 75 VA capacity supports typical low-voltage HVAC control loads
• 24-volt secondary output matches standard thermostat and control board requirements
• Wire leads and quick-connect terminations simplify field replacement
• Single SKU covers multiple primary voltage configurations

Compatibility

Designed as an OEM-style replacement transformer for residential and light commercial HVAC control circuits requiring a 75 VA, 24-volt secondary with a multi-tap primary voltage input.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified electrician in accordance with applicable NEC requirements. Disconnect and lock out all power to the unit before removing the existing transformer or making any wiring connections. Verify that the correct primary tap is selected for the supply voltage present at the equipment before energizing. Do not exceed the 75 VA load rating on the secondary circuit.
