Appleton HS20F500B Transformer 0.5 Kva 120x240v to 16/32V

Product Description

The APPLETON HS20F500B is a heavy-duty step-down transformer rated at 0.5 KVA, designed to convert 120/240-volt primary input to 16/32-volt secondary output. This transformer is built for demanding electrical distribution and control applications where consistent, stable voltage transformation is required. Weighing 21.7 pounds and sized at 6.9 x 12.3 x 6.2 inches, it is a compact but robust unit suited for panel, enclosure, or equipment-mounted installations. Licensed electricians and industrial controls technicians are the primary installers of this device.

This transformer is commonly used in commercial and light industrial electrical systems where 16-volt or 32-volt control circuits need to be powered from a standard 120/240-volt supply. Typical applications include building automation control panels, HVAC control systems, and low-voltage signaling or alarm circuits. Its 0.5 KVA capacity makes it appropriate for small control loads requiring reliable stepped-down voltage.

Key Features

• 0.5 KVA capacity for small control circuit applications
• Primary voltage: 120/240 volts for compatibility with standard single-phase supply
• Secondary voltage: 16/32 volts for low-voltage control circuit service
• Heavy-duty construction rated for demanding installation environments
• Compact footprint at 6.9 x 12.3 x 6.2 inches for panel or enclosure mounting

Compatibility

Designed as an OEM-style replacement or direct-install transformer for low-voltage control circuit applications requiring 16/32-volt secondary output from a 120/240-volt primary source.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize all circuits and verify the absence of voltage before beginning any wiring work. Ensure the transformer is properly grounded and that the enclosure or mounting surface is rated for the unit weight. Verify secondary load does not exceed the 0.5 KVA rating before energizing.
