Appleton HS19F500B Control Transformer 0.5 Kva 120-240V

Product Description

The APPLETON HS19F500B is a heavy-duty control transformer rated at 0.5 KVA with a 120-240 volt primary and a 12/24 volt secondary. It steps down line voltage to low-voltage control circuits commonly found in industrial machinery, HVAC control panels, and commercial electrical systems. Built for demanding environments, this unit is suited for installation by licensed electricians and industrial maintenance technicians who require a reliable, compact step-down transformer for machine control or low-voltage relay circuits. The unit weighs 21.7 pounds and measures 12.2 inches long by 6.8 inches wide by 6.3 inches tall, making it appropriate for panel or enclosure mounting where space is constrained.

This transformer is intended for use in control circuit applications where line voltage must be reduced to 12 or 24 volts for relay coils, solenoids, or low-voltage control devices. Typical installations include industrial control panels, HVAC rooftop units, motor control centers, and commercial building automation equipment. The dual primary voltage configuration at 120 and 240 volts provides flexibility across a range of North American electrical service configurations.

Key Features

• 0.5 KVA rated capacity for light to medium control circuit loads
• Dual primary voltage: 120 volts and 240 volts
• Dual secondary voltage output: 12 volts and 24 volts
• Heavy-duty construction suited for industrial and commercial environments
• Compact footprint at 12.2 x 6.8 x 6.3 inches for panel or enclosure mounting

Compatibility

Designed as an OEM-style replacement or new-installation control transformer for industrial control panels, commercial HVAC systems, and motor control applications requiring 0.5 KVA step-down transformer service at 120-240 volt primary input.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit before making any wiring connections. Ensure the transformer is mounted securely in a suitable enclosure rated for the application environment. Verify primary tap selection matches the available line voltage before energizing.
