Hammond PH75MLI-FK Control Transformer 75VA

Product Description

The HAMMOND PH75MLI-FK is a 75 VA control transformer designed to step down line voltage to a lower control-circuit voltage in HVAC, industrial, and commercial electrical systems. Control transformers of this type are used to power low-voltage control circuits, relays, contactors, and auxiliary devices that require a stable, isolated voltage supply. The 75 VA rating indicates the transformer can handle 75 volt-amps of continuous load, making it a standard working capacity for most residential and light-commercial control applications. Licensed electricians and HVAC technicians are the primary installers of this component.

This transformer is suited for use in HVAC control panels, motor control centers, and general-purpose low-voltage control circuits in both residential and commercial installations. It is typically mounted inside electrical enclosures or equipment panels where space and load requirements align with its 75 VA capacity. Applications include furnace control boards, air handler panels, and industrial relay logic circuits that require reliable step-down transformer isolation.

Key Features

• 75 VA continuous load capacity suitable for standard control-circuit applications
• Designed for low-voltage control circuit isolation in HVAC and industrial systems
• Panel-mount style construction for use inside electrical enclosures
• Provides stable, isolated secondary voltage for relays, contactors, and control boards

Compatibility

Designed as an OEM-style replacement or direct-install control transformer for residential and light-commercial HVAC systems, motor control panels, and general-purpose control circuits requiring a 75 VA step-down transformer.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician in accordance with NEC requirements. De-energize and lockout-tagout the panel or equipment before beginning any wiring work. Verify that the primary voltage at the installation site matches the transformer primary rating before connecting. Ensure the secondary load does not exceed the 75 VA rating to prevent overheating or premature failure.
