Overview
The Hammond Manufacturing 166M6 is a low voltage industrial power transformer designed for chassis mounting. It features a single primary winding rated at 115 VAC and a single secondary winding providing 6.3 VAC center-tapped output. The unit delivers an 18.9 VA power rating with a maximum secondary current of 3 A. Operating frequencies include 50 Hz and 60 Hz. Physical dimensions are 3.25 inches in length, 2.00 inches in width, and 2.00 inches in height. The device operates within a temperature range of 0°C to +130°C and utilizes wire leads for termination.
Feature Summary
- Chassis mount construction with wire lead terminations
- Single primary and single secondary winding configuration
- Low voltage step-down capability for industrial control applications
Applications
- Industrial control panels requiring isolated low voltage power
- Equipment needing 6.3V center-tapped supply for rectification
- General purpose AC to DC power conversion stages
Procurement Notes
Verify the specific ordering suffix against the manufacturer datasheet to ensure correct voltage and current ratings. Confirm that the chassis mounting style and wire lead termination match the system integration requirements. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure input voltage matches the 115 VAC specification before installation.
Selection Notes
Select this component when a compact, chassis-mounted transformer is required for low voltage applications. The 18.9 VA rating supports loads up to 3 A at 6.3 VAC. Consider the physical footprint of 3.25 x 2.00 x 2.00 inches for enclosure space planning. The wide operating temperature range allows use in varied industrial environments without derating concerns under normal conditions.
Part Context
