HPI-17

Overview

The Signal Transformer HPI-17 is a laminated core power transformer with a maximum power rating of 1750VA. It features dual primary windings supporting 115V and 230V inputs, and dual secondary windings configured for parallel 115V or series 230V outputs. Maximum output currents are 15.2A in parallel mode and 7.6A in series mode. The unit provides 4000Vrms isolation voltage and utilizes chassis mounting with terminal block connections. Physical dimensions are 179.30mm length, 149.70mm width, and 154.90mm height.

Feature Summary

• Dual primary winding configuration allows flexible input voltage selection between 115V and 230V.
• Dual secondary windings enable versatile output configurations for parallel or series operation.
• High isolation voltage capability ensures safety compliance in industrial applications.
• Robust laminated core construction supports high power handling requirements.

Applications

• Industrial power supply systems requiring high capacity
• Equipment needing isolated power distribution
• Chassis-mounted power conversion units

Procurement Notes

Verify the specific voltage configuration required for your application, as the HPI-17 supports multiple primary and secondary setups. Confirm that the chassis mounting style and terminal block connections align with your enclosure design. Ensure the physical footprint and weight capacity of your installation site can accommodate the transformer's dimensions and mass. Check for any regional shipping restrictions due to size or weight limitations before ordering.

Selection Notes

Select the HPI-17 when a high-power, isolated transformer is needed for industrial environments. Consider the dual winding flexibility if your system requires adaptable voltage inputs or outputs. Evaluate the chassis mount requirement against available space. Compare the 1750VA rating against peak load demands to ensure adequate headroom. Verify insulation class and temperature ratings match operational conditions.

Part Context

The HPI-17 belongs to the HPI series of high-power international transformers from Signal Transformer. This series is designed for demanding industrial applications where reliability and high power density are critical. The laminated core technology distinguishes it from switch-mode alternatives, offering robust performance at standard line frequencies.

Replacement Considerations

Direct replacements must match the 1750VA rating, 115V/230V primary options, and corresponding secondary configurations. Verify dimensional compatibility for chassis mounting. Ensure equivalent isolation voltage and terminal block interface. Consult manufacturer cross-reference lists for approved equivalents.
