Overview
The Hammond Manufacturing 166G14 is an industrial power transformer designed for chassis mounting. It features a single primary winding rated at 115 VAC and 60 Hz, coupled with a single secondary winding providing 14 VAC center-tapped output. The unit delivers a power rating of 7 VA with a maximum secondary current of 500 mA. Physical dimensions are 71.37 mm in length, 38.1 mm in width, and 42.93 mm in height. It operates within a temperature range of 0°C to +130°C and utilizes wire lead terminations.
Feature Summary
- Provides high voltage isolation of 2000Vrms for safe operation in demanding environments.
- Constructed with a laminated core to ensure efficient power transformation.
- Features UL and CSA approval agencies for compliance with safety standards.
Applications
- Industrial control panels requiring low voltage AC power
- Chassis-mounted equipment needing isolated power supplies
- General purpose industrial automation systems
Procurement Notes
Verify the specific part number 166G14 against official Hammond Manufacturing datasheets to confirm electrical ratings and physical dimensions. Ensure compatibility with existing chassis mounting holes and wire lead connections. Confirm that the 115V primary input matches your system's supply voltage. Check for required safety certifications such as UL or CSA depending on regional regulations.
Selection Notes
Select this model when a 7 VA capacity is sufficient for the load requirements. The 14V center-tapped secondary is suitable for applications requiring dual polarity voltages. Consider the chassis mount style and wire lead termination method during integration. Verify that the operating temperature range meets the environmental conditions of the installation site.
Part Context
This component belongs to the Hammond 166 series of industrial control transformers. The series offers various power ratings and voltage configurations while maintaining consistent chassis mounting dimensions and construction quality.
