E100E

Overview

The SolaHD E100E is a 100 VA industrial control transformer featuring dual primary windings rated for 120 V and 240 V, providing a single 24 V secondary output. It utilizes an interleaved copper winding design to minimize I2R losses and maximize efficiency. The unit employs epoxy encapsulation (SBE) to shield the core and coils from moisture, dirt, and contaminants. It supports 50/60 Hz operation and offers IP20 touch-proof terminations with molded terminal barriers to prevent arcing. The transformer is designed for chassis or panel mounting using screw-type connections.

Feature Summary

• Epoxy encapsulated construction protects internal components against environmental hazards
• Interleaved copper windings reduce electrical losses and enhance operational efficiency
• Dual primary winding configuration allows flexible voltage input selection
• Molded terminal barriers provide enhanced safety by preventing electrical arcing

Applications

• Industrial machinery control circuits
• Panel-mounted power distribution systems
• Equipment requiring isolated 24 VAC control power
• Harsh industrial environments demanding contaminant protection

Procurement Notes

Verify that the specific order matches the required primary voltage configuration, as the E100E supports multiple input ratings. Confirm that the mounting style aligns with the chassis or panel requirements of the target application. Ensure compliance with local safety standards regarding IP20 touch-proof terminations. Cross-reference the datasheet for exact dimensional constraints to guarantee physical fit within the enclosure. Validate that the frequency rating meets the system's operational specifications.

Selection Notes

Select the E100E when a robust, encapsulated transformer is needed for industrial control applications. Its dual primary capability simplifies inventory management across different voltage regions. The epoxy encapsulation makes it suitable for environments where dust or moisture exposure is likely. Consider this model over non-encapsulated variants if long-term reliability in harsh conditions is a priority. The standardized coil design ensures compatibility with various worldwide voltage combinations.

Part Context

The E100E belongs to the SolaHD SBE series of industrial control transformers. This series is characterized by rugged construction and comprehensive epoxy encapsulation. These units are engineered to withstand challenging industrial settings while maintaining electrical integrity. The SBE designation indicates specific protective features against environmental degradation. This component serves as a reliable step-down solution for converting higher line voltages to standard control levels.

Replacement Considerations

The E100EWB is a factory-wired variant of the E100E base unit, incorporating additional components like FBPC1 and FB2X. Verify if the pre-wired configuration is necessary for the application. Standard replacement requires matching the 100 VA rating and 24 V secondary output. Ensure the replacement maintains the same encapsulation type and mounting style.
