Overview
The Hammond Manufacturing 166E12-BULK is an industrial power transformer designed for low voltage applications. It features a single primary winding rated at 115 VAC and a secondary output of 12.6 VAC center-tapped. The unit provides a power rating of 1.8 VA with a maximum secondary current of 150 mA. Designed for chassis mounting, it utilizes wire leads for termination. The transformer operates within a temperature range of 0°C to +130°C and supports frequencies of 50 Hz or 60 Hz.
Feature Summary
- Single primary winding configuration for standard 115 VAC input
- Center-tapped secondary output suitable for rectifier circuits
- Chassis mount style with wire lead terminations
Applications
- Low voltage industrial control systems
- Rectifier use in power supply circuits
- General purpose industrial equipment requiring isolated AC power
Procurement Notes
Verify the specific suffix against official documentation to confirm packaging and shipping restrictions. Ensure the required voltage and current ratings match the application load. Confirm compliance with regional import regulations regarding product dimensions or weight if applicable. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity and correct specification alignment.
Selection Notes
Select this component when a compact, low-power transformer is needed for chassis-mounted installations. The 1.8 VA rating suits light loads requiring 12.6 VAC center-tapped output. Consider the physical dimensions and wire lead length during mechanical design. Verify that the operating temperature range meets the environmental conditions of the intended enclosure.
Part Context
This model belongs to the Hammond 166 series of industrial control transformers. The series offers various power ratings and voltage configurations tailored for general industrial use. These transformers are characterized by their robust construction and suitability for mounting directly onto equipment chassis panels.
Replacement Considerations
Consult official Hammond Manufacturing cross-reference lists for verified substitutes. Ensure any replacement matches the 1.8 VA power rating, 115 VAC primary, and 12.6 VAC CT secondary specifications. Physical compatibility including chassis mount footprint and terminal type must be confirmed.
