SolaHD Low Temperature Rise Ventilated Transformers transformers are used to change voltage, provide isolation and support industrial, automation or distribution loads with a transformer construction matched to the application.
SolaHD transformer families vary by VA/kVA, single- or three-phase configuration, primary and secondary voltage, enclosure style, winding material, temperature rise, K-factor or drive-isolation duty, and whether the unit is intended for control-panel, machine or facility distribution service.
For a correct selection, verify primary and secondary voltage, phase, frequency, VA/kVA, load type, enclosure/mounting and applicable code or efficiency requirements. For control transformers, also check inrush and fuse-clip or terminal requirements.
General-purpose and automation transformers are not interchangeable with K-factor, drive-isolation or low-temperature-rise designs simply because the voltage and kVA match. Those families are engineered around different load characteristics and thermal or harmonic demands.
Buck-boost transformers require the intended connection to be established from source voltage, desired load voltage, phase and load current. Control transformers should be sized for both sealed VA and the inrush of contactors, relays or solenoids.
When replacing an installed unit, match the nameplate electrical data and enclosure/footprint, then confirm any efficiency, temperature-rise, winding and installation requirements before changing series.
Provide primary voltage, secondary voltage, phase, frequency, VA/kVA, load type and mounting or enclosure requirements.
No. K-factor, drive-isolation, low-temperature-rise, control and general-purpose transformers are designed for different applications and must be selected accordingly.
