E100W

Overview

The SolaHD E100W is a 100 VA industrial control transformer from the SBE series, featuring an encapsulated copper-wound design. It supports dual primary voltages of 240 V and 480 V with a single secondary output of 120 V. The unit utilizes a laminated core and operates at 50/60 Hz frequencies. Physical dimensions are approximately 3.39 inches in width, 4.61 inches in depth, and 4.41 inches in height. It employs chassis mounting and includes pre-installed primary fusing blocks and built-in midget-type secondary fuses for circuit protection.

Feature Summary

• Epoxy-encapsulated construction for environmental protection
• Integrated primary fusing block and secondary fuse provisions
• Dual primary winding configuration for flexible voltage input
• Laminated core design optimized for industrial control applications

Applications

• Industrial control panel power distribution
• Machine tool auxiliary power supply
• Electrical enclosure isolation
• Control circuit voltage transformation

Procurement Notes

Verify that the specific order matches the E100W model designation rather than similar variants like E100WB or E100D, as physical dimensions and internal fuse configurations may differ. Confirm that the required primary voltage rating aligns with the available 240 V or 480 V options. Ensure that the application environment does not exceed the thermal limits defined in the official datasheet. Cross-reference the UL listing status if operating in regulated jurisdictions.

Selection Notes

Select this component when a robust, encapsulated transformer is required for standard 50/60 Hz industrial environments. The dual primary capability allows compatibility with both 240 V and 480 V supply lines without rewiring. The integrated fusing reduces bill of materials complexity compared to bare transformers. Consider the chassis mount style for secure installation within control cabinets where space constraints require compact, standardized form factors.

Part Context

The E100W belongs to the SBE series of industrial control transformers manufactured by SolaHD. This series is characterized by epoxy encapsulation and copper windings, designed for durability in harsh industrial settings. It serves as a fundamental component for stepping down line voltage to control levels, providing isolation and safety for downstream electronic controls and relays.
