Overview
The Hammond Manufacturing 160H20-BULK is a low voltage power transformer designed for PCB mounting. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50 Hz or 60 Hz. The secondary output provides 20 VAC center-tapped configuration with a current rating of 1.2 A, delivering a total power capacity of 24 VA. The unit utilizes solder pin termination for through-hole installation. Physical dimensions are 2.25 inches in length, 1.63 inches in width, and 1.38 inches in height. It operates within a temperature range of 0°C to +130°C.
Feature Summary
- Dual primary winding capability supports flexible input voltage selection between 115 VAC and 230 VAC.
- Center-tapped secondary design enables versatile rectification and signal processing applications.
- Through-hole solder pin termination ensures secure mechanical attachment to printed circuit boards.
Applications
- Low voltage power supply circuits requiring isolated AC sources
- Industrial control panels utilizing standard line voltages
- Electronic equipment needing 20V center-tapped secondary outputs
Procurement Notes
Verify the specific suffix against manufacturer documentation to confirm bulk packaging status and terminal configuration. Ensure the ordered part matches the required electrical ratings and physical footprint for the target PCB layout. Cross-reference the datasheet for insulation class and thermal limits before integration into the final assembly design.
Selection Notes
Select this component when a compact, board-mount solution is required for 24 VA applications. The dual primary winding allows compatibility with both 115V and 230V mains without rewinding. Verify that the through-hole spacing and housing dimensions fit the available PCB area and enclosure constraints.
Part Context
This model belongs to the Hammond 160 series of low voltage transformers. These units are engineered for general-purpose industrial and commercial electronics. The series emphasizes reliability and compliance with standard safety regulations for enclosed equipment.
Replacement Considerations
Consult official substitution lists for equivalent transformers with matching VA ratings and pin configurations. Verify that any alternative part maintains the same center-tapped secondary voltage and current capabilities.
