Appleton HS1F1BS Isolation Transformer 1.0 Kva 240x480 to 120/240V

Product Description

The APPLETON HS1F1BS is a single-phase isolation transformer rated at 1.0 KVA with a primary voltage of 240x480 volts and a secondary voltage of 120/240 volts. Isolation transformers separate the primary and secondary circuits galvanically, reducing noise, protecting downstream equipment, and improving personnel safety. This unit is suited for industrial, commercial, and heavy-duty electrical installations where clean, isolated power is required. Licensed electricians install this type of transformer as part of panel feed, machine tool, or control circuit work. At 28.85 pounds and compact dimensions, it is manageable for single-technician installation in enclosures or junction boxes.

The HS1F1BS is designed for applications requiring a step-down or voltage-centering function from a 240-volt or 480-volt primary supply to a 120/240-volt secondary output. Typical use cases include industrial control panels, machine tools, commercial HVAC control circuits, and electrical distribution systems where line isolation is needed to protect sensitive electronics or meet code requirements. This transformer is appropriate for both new installations and retrofit scenarios in commercial and light industrial settings.

Key Features

• 1.0 KVA capacity suitable for control circuit and light load applications
• Dual primary voltage accepts 240-volt or 480-volt input
• 120/240-volt secondary output supports split-phase downstream loads
• Isolation design eliminates direct electrical connection between primary and secondary windings
• Compact footprint at 6.8 inches x 11.2 inches x 6.4 inches for enclosure mounting
• Rated at 28.85 pounds for manageable field installation

Compatibility

Designed as an OEM-style isolation transformer for industrial and commercial single-phase electrical systems requiring 240x480-volt primary to 120/240-volt secondary conversion.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the primary supply circuit before making any wiring connections. Verify that the primary tap matches the available supply voltage before energizing. Ensure the transformer is mounted securely in a location with adequate ventilation to prevent heat buildup during operation.
