The SolaHD E500 is a 500 VA SBE Series epoxy-encapsulated, copper-wound industrial control transformer configured for 220-480 VAC primary to 110-120 VAC secondary. Standard model with included FB2X secondary fuse holder for a midget-type cartridge fuse; fuse not included.
Selecting the correct control transformer requires more than matching the primary and secondary voltage. Industrial control devices such as contactors, relays, solenoids, and motor starters may draw several times their normal operating current when first energized. The transformer must provide enough continuous capacity for the steady-state load while maintaining sufficient secondary voltage during maximum inrush conditions.
Before selecting a SolaHD control transformer, identify the available supply voltage, required control voltage, total sealed VA, total inrush VA, operating frequency, environmental conditions, mounting requirements, and any required domestic or international certifications. The transformer continuous VA rating must exceed the total sealed load, and its inrush performance must be sufficient for all control devices that may energize simultaneously.
| Series | Best For |
|---|---|
| SBE Encapsulated | Standard industrial control panels requiring copper windings, low temperature rise, and protection from moisture, dirt, and contaminants |
| SBE Open Style | Higher-capacity control circuits with large electromagnetic loads and strong voltage-regulation requirements |
| SMT Open Style | Economical higher-capacity applications using compact aluminum-wound open-style construction |
| SBE International | International machinery and export equipment requiring multiple voltage taps and IEC-oriented configurations from 50 to 750 VA |
| ICE International | Higher-capacity international equipment requiring copper windings, encapsulated construction, and IP20 touch-safe terminations |
| HSZ Enclosed | Outdoor, washdown, dusty, corrosive, or high-temperature applications where the transformer must be mounted outside the control panel |
If you're unsure which SolaHD control transformer is best for your application, our team can help identify the correct series and catalog number based on your primary voltage, secondary voltage, sealed VA, inrush VA, winding preference, mounting requirements, and operating environment.
