1182M22

Overview

The Hammond Manufacturing 1182M22 is a toroidal power transformer designed for industrial control applications. It features a dual primary winding rated for 117 VAC and 234 VAC, allowing compatibility with standard 115 VAC and 230 VAC supply lines. The unit provides a dual secondary output configuration: 44 VAC at 2.73 A in series mode, or 22 VAC at 5.46 A in parallel mode. With a total power rating of 120 VA, it utilizes wire leads for termination and is intended for chassis mounting. The transformer operates at frequencies of 50 Hz and 60 Hz.

Feature Summary

• Toroidal core construction minimizes stray magnetic flux leakage and electromagnetic interference (EMI).
• Dual primary windings enable flexible input voltage selection between 115 VAC and 230 VAC.
• Dual secondary windings allow configurable output voltages via series or parallel connection.
• Low-profile design facilitates integration into compact industrial control enclosures.

Applications

• Industrial control panels requiring isolated power supplies.
• Electronic equipment needing low-EMI power conversion.
• Chassis-mounted systems utilizing 115 VAC or 230 VAC mains input.

Procurement Notes

Verify the specific secondary voltage requirement (22V vs 44V) against the application circuit before ordering. Confirm that the chassis mounting style and wire lead termination are compatible with the target enclosure design. Ensure the operating frequency matches the local power grid standards. Cross-reference the datasheet to confirm RoHS compliance status if required by project specifications.

Selection Notes
