1182L22

Overview

The Hammond Manufacturing 1182L22 is an industrial toroidal power transformer rated at 80 VA. It features dual primary windings supporting 115 VAC and 230 VAC inputs, and dual secondary windings providing a 44 VCT output in series or 22V @ 3.64A in parallel operation. Designed for chassis mounting with wire lead termination, it operates at 50 Hz/60 Hz frequencies. The unit measures 1.5 inches in height and weighs 1.361 kg.

Feature Summary

• Toroidal core construction ensures low stray magnetic flux leakage and reduced electromagnetic interference (EMI).
• Dual primary and secondary winding configurations allow flexible voltage input and output arrangements.
• Low profile design facilitates integration into compact industrial control enclosures.

Applications

• Industrial control systems requiring isolated power supplies
• Electronic equipment needing low EMI power conversion
• Chassis-mounted instrumentation power distribution

Procurement Notes

Verify the specific voltage configuration required for your application, as this model supports both series and parallel secondary connections. Confirm that the chassis mounting style and wire lead terminations are compatible with your enclosure design. Ensure the 80 VA power rating meets the load requirements of the connected circuitry to prevent overheating or performance degradation during continuous operation.

Selection Notes

Select this component when low electromagnetic interference is critical for sensitive electronic circuits. The dual primary winding capability allows compatibility with varying global line voltages without external switching. Consider the physical dimensions and weight constraints of the installation site, as the toroidal shape and metal casing require specific clearance and mechanical support within the assembly.
