373DX

Power Transformers Overview

The Hammond Manufacturing 373DX is a 101VA industrial power transformer with a laminated core and chassis mount design. It features dual multi-tap primary windings for 100V, 110V, 120V, 200V, 220V, and 240V inputs. Secondary outputs include a 700V center-tapped winding at 104mA, a 6.3VCT winding at 3A, and a 5VCT winding at 2A. The unit provides 2000Vrms isolation and measures 87.27mm x 79.38mm x 96.52mm.

Power Transformers Feature Summary

• Dual multi-tap primary windings support multiple input voltage configurations
• Triple secondary configuration includes high voltage, filament, and bias taps
• Laminated core construction ensures stable industrial performance
• Chassis mounting style with wire lead terminations

Power Transformers Applications

• Industrial automation control panels
• High voltage test equipment power supplies
• Vacuum tube amplifier circuits requiring filament and bias voltages
• Medical or laboratory instrumentation power systems

Power Transformers Procurement Notes

Verify the specific secondary tap requirements against your circuit design before ordering. Confirm that the 101VA rating meets the total load demand of all connected components. Ensure physical clearance accommodates the 96.52mm height and standard chassis mounting holes. Check for RoHS3 compliance if required by your manufacturing standards.

Power Transformers Selection Notes

Select this model when a single transformer must provide distinct high voltage, filament, and low voltage DC rectification inputs. Compare the 101VA capacity against peak load currents to prevent saturation. Consider the 2000Vrms isolation rating for safety in sensitive applications. Verify that the dual primary taps match the available facility power supply voltages.

Power Transformers Part Context

This component belongs to the Hammond 300 Series, which specializes in industrial power transformers. The series offers various VA ratings and winding configurations for general-purpose and specialized industrial applications. The 373DX specifically addresses needs for combined high voltage and filament power in a compact chassis-mount form factor.

Power Transformers Replacement Considerations

Direct substitutes within the same series include models with similar VA ratings and winding configurations. Verify that any replacement maintains the 700V CT secondary specification and compatible primary tap options. Physical dimensions and mounting hole patterns must match existing chassis cutouts to ensure proper installation without modification.
