1182W12

Overview

The Hammond Manufacturing 1182W12 is a toroidal power transformer from the 1182 series, rated at 1000 VA. It features dual primary windings supporting 115 VAC and 230 VAC inputs. The secondary output provides 12V at 83.4A, with an additional center-tapped configuration of 12/12V available. Designed for chassis mounting, it utilizes wire leads for termination. The unit exhibits low stray magnetic flux leakage, contributing to reduced electromagnetic interference (EMI).

Feature Summary

• Toroidal core construction designed for high efficiency and compact form factor.
• Low stray magnetic flux leakage characteristics to minimize electromagnetic interference.
• Dual primary winding capability for flexible voltage input configurations.

Applications

• Industrial power supply systems requiring robust voltage conversion.
• Chassis-mounted equipment needing high-current DC power sources.
• Audio or sensitive electronic applications benefiting from low EMI profiles.

Procurement Notes

Verify that the specific order matches the 1182W12 part number, as the 1182 series includes variants with different voltages and VA ratings. Confirm the secondary configuration requirements, specifically whether the standard 12V output or the 12/12V center-tapped version is needed. Ensure the installation environment supports chassis mounting and that the wire lead terminations are compatible with the target circuit board or terminal block connections.

Selection Notes

Select this model when a 1000 VA capacity is required with a 12V secondary output. The dual primary design allows operation in regions with either 115V or 230V mains supplies without rewiring. Consider the physical dimensions and chassis mounting style during enclosure design. Compare against other 1182 series models if higher or lower power ratings are necessary, ensuring the selected variant meets the specific current and voltage demands of the application.

Part Context

This component belongs to the Hammond Manufacturing 1182 series of toroidal power transformers. The series is characterized by low profile designs and high efficiency. Other models in the family offer varying VA ratings and secondary voltage configurations, such as the 1182U110 which provides higher voltage outputs. The 1182W12 specifically addresses applications needing substantial current delivery at low voltage.

Replacement Considerations

Direct replacement requires matching the 1000 VA rating, 12V secondary output, and toroidal form factor. Verify that any substitute maintains the dual primary winding specification for 115V/230V compatibility. Ensure the replacement part supports chassis mounting and has compatible wire lead terminations. Cross-reference with other 1182 series parts only if electrical parameters align exactly.
