E300

Overview

The SolaHD E300 is a 300 VA encapsulated industrial control transformer from the SBE series. It features an epoxy-encapsulated design with interleaved copper windings to reduce I2R losses and maximize efficiency. The unit is configured for a primary voltage of 240 VAC or 480 VAC and provides a secondary output of 120 VAC at 50/60 Hz. It operates within a temperature range of 0°C to +105°C and utilizes a 55°C rise with 105°C insulation class. The transformer employs a laminated core and chassis mount configuration, offering IP20 touch-proof terminations.

Feature Summary

• Epoxy encapsulation seals windings against moisture and dirt
• Interleaved copper windings minimize resistive losses
• IP20 touch-proof termination design ensures operator safety

Applications

• Industrial control panel auxiliary power
• Voltage step-down for control circuits
• General industrial machinery isolation

Procurement Notes

Verify the specific datasheet version for the E300 model to confirm exact terminal configurations and mounting hole dimensions. Ensure the input voltage matches the available supply (240V or 480V) as specified in the official documentation. Confirm that the ambient operating temperature remains within the 0°C to +105°C range defined by the manufacturer. Cross-reference the part number with current product availability lists to ensure active status.

Selection Notes

Select this component when a 300 VA capacity is required for isolating control circuits from main power lines. The epoxy encapsulation makes it suitable for environments where protection against dust and moisture is necessary. Verify that the chassis mount style fits the enclosure constraints. The 55°C rise rating should be considered for thermal management planning within closed control panels.

Part Context

The E300 belongs to the SolaHD SBE series of encapsulated industrial control transformers. This series is characterized by its robust construction using epoxy resin to protect internal components. The brand SolaHD, now part of Emerson, specializes in power quality solutions including transformers and surge protection devices. The E300 represents a standard capacity option within their broader portfolio of industrial-grade power conversion equipment.

Replacement Considerations

Consult official substitution guides for equivalent 300 VA encapsulated transformers. Verify compatibility regarding primary/secondary voltage ratios and physical mounting dimensions before replacing existing units.
