FAQs
Plan for the unit’s dimensions (5.5 in length, 5.875 in height, 5.25 in width) and mount within the panel using molded-in terminals. Use the factory-mounted two-pole primary fuse block for safety and reliable primary protection. Route primary leads to 200/220/440 V or 208/230/460 V supplies and connect the appropriate secondary windings (23/110, 24/115, 25/120) to the control circuit, ensuring proper clearance and cooling for 300 VA loads.
Primary voltage options are 200/220/440 V, 208/230/460 V, and 240/480 V. Secondary voltages are 23/110 V, 24/115 V, and 25/120 V. The transformer is rated at 300 VA, supporting typical control circuits in automation panels while maintaining voltage stability across duty cycles.
Yes. It operates at both 50 Hz and 60 Hz and is RoHS compliant with CSA, UL Listed, and cUL Certified, meeting common safety and environmental standards required in manufacturing and processing environments.
Its epoxy encapsulation, copper windings, molded-in terminals, and integrated primary fuse block simplify installation, reduce wiring errors, and improve reliability. The unit’s multiple voltage options and 300 VA rating accommodate a range of control circuits, making it versatile for retrofits and new builds alike.
The transformer carries a one-year warranty from installation or eighteen months from shipment, whichever occurs first. Routine inspection of connections, fuse block integrity, and cooling clearance helps maintain reliability and minimizes downtime in ongoing operations.
