182H9

Overview

The Hammond Manufacturing 182H9 is a toroidal power transformer designed for chassis mounting. It features a power rating of 15VA and operates with primary voltages of 115V or 230VAC at 50/60Hz. The unit provides dual secondary outputs, each delivering 12VAC at 0.625A. Constructed with an epoxy encapsulated core for vibration resistance, it utilizes insulated leads for connection. The component is UL recognized and complies with RoHS standards, suitable for compact industrial applications requiring reliable isolated power conversion.

Feature Summary

• Toroidal core construction for efficient magnetic coupling and reduced electromagnetic interference
• Epoxy encapsulation to provide mechanical stability and resistance against vibration
• Dual independent secondary windings for simultaneous multi-rail power distribution
• Chassis mount design optimized for integration into enclosed equipment frames

Applications

• Industrial control panel power supplies
• Test and measurement instrument internal power systems
• Medical device power modules
• Audio equipment amplification stages

Procurement Notes

Verify the specific primary voltage configuration required (115V vs 230V) prior to ordering, as input specifications are critical for safe operation. Confirm that the lead wire length meets the spatial constraints of the intended chassis assembly. Ensure compliance with local electrical safety regulations and verify that the 15VA thermal rating is sufficient for the continuous load requirements of the target application environment.

Selection Notes

Select this model when space efficiency and low noise are prioritized over cost, as toroidal designs offer superior performance in compact footprints. Consider the dual secondary output capability if separate isolated rails are needed without additional components. Evaluate the insulation class and temperature rise characteristics to ensure compatibility with the ambient operating conditions of the final enclosure. Compare against rectangular transformers only if significant weight reduction is not a primary design constraint.

Part Context

This component belongs to Hammond Manufacturing's line of general-purpose power transformers. It serves as a fundamental energy conversion element within electronic systems, stepping down mains voltage to lower AC levels for rectification. The 182H9 represents a standard offering in their chassis-mount series, balancing performance with ease of installation for OEMs designing custom power solutions.
