Overview
The Hammond Manufacturing 166FB24 is a low voltage filament power transformer designed for chassis mounting. It features a dual primary winding configuration supporting 115 VAC and 230 VAC inputs at 50 Hz or 60 Hz frequencies. The unit delivers a 9.6 VA power rating with a secondary output of 24 VAC center-tapped, providing up to 0.4 A current. Constructed with wire leads for termination, the transformer operates within a temperature range of 0°C to +130°C. Its physical dimensions are 71.62 mm in length, 42.92 mm in width, and 42.92 mm in height, weighing approximately 362.87 g.
Feature Summary
- Dual primary winding capability allows flexible connection to either 115 VAC or 230 VAC supply lines.
- Center-tapped secondary design facilitates rectifier applications requiring balanced voltage distribution.
- Chassis mount style with horizontal channel bracket options ensures secure installation in industrial enclosures.
Applications
- Industrial control systems requiring low voltage isolation
- Filament heating circuits for vacuum tubes or specialized lighting
- Rectifier power supplies for electronic instrumentation
Procurement Notes
Verify that the input supply voltage matches the specific primary winding configuration required for your application, as the unit supports both 115 VAC and 230 VAC. Confirm that the chassis mounting space accommodates the specified length and width dimensions. Ensure that the wire lead lengths are sufficient for your internal wiring layout before finalizing the procurement order.
Selection Notes
Select this model when a compact, economical solution is needed for low voltage applications requiring dual primary flexibility. Consider the 9.6 VA power limit to ensure it meets the load requirements without overheating. The center-tapped secondary is ideal if subsequent circuitry requires a split voltage source for full-wave rectification or bipolar signaling.
Part Context
This component belongs to the Hammond 166 series of industrial control transformers. The series is characterized by laminated core construction and robust chassis mounting capabilities. It serves as a standard interface between mains power and low voltage control circuits in various industrial environments.
