E250

Overview

The SolaHD E250 is a 250 VA industrial control transformer from the SBE series. It features dual primary windings rated for 120 V and 240 V, providing a single secondary output of 24 V at 60 Hz. The unit utilizes interleaved copper windings to minimize I2R losses and employs epoxy encapsulation for environmental protection. Physical dimensions are 5.36 inches in length, 4.5 inches in width, and 5.21 inches in height. It supports bracket mounting and weighs approximately 5 kg.

Feature Summary

• Epoxy encapsulation protects internal components against moisture, dirt, and contaminants
• Interleaved copper windings reduce electrical losses and maximize operational efficiency
• Dual primary winding configuration allows flexibility for different input voltage standards

Applications

• Industrial control panel power distribution
• Machine tool auxiliary circuit isolation
• General factory automation equipment power supply

Procurement Notes

Verify the specific ordering suffix required for your application, as variants such as E250EW indicate prewired configurations without covers. Confirm that the selected model matches the necessary lead wire or terminal style. Ensure the enclosure type meets the IP rating requirements of the installation environment before finalizing the purchase order.

Selection Notes

Select this component based on the 250 VA power requirement and the specific need for a 24 V secondary output. The dual primary capability makes it suitable for facilities with varying standard voltages. Consider the physical footprint and bracket mounting style when designing the control panel layout to ensure adequate clearance and secure installation.

Part Context

This transformer belongs to the SolaHD SBE series, which consists of encapsulated industrial control transformers. The brand has provided power conversion solutions since 1915, focusing on reliability and durability. This specific model represents a standard encapsulated design intended for robust performance in demanding industrial environments.

Replacement Considerations

Direct replacements must match the 250 VA rating, 24 V secondary output, and dual primary input capabilities. Verify that any substitute part maintains the same physical dimensions and mounting style to fit existing panel cutouts. Check for equivalent encapsulation standards to ensure comparable environmental protection levels.
