FAQs
Begin by verifying the primary voltage setting matches your incoming supply (200/220/440 V, 208/230/460 V, or 240/480 V). Use the molded-in terminals for field connections and the factory-mounted two-pole primary fuse block for fuse protection. Mount the unit securely, observe clearance for heat dissipation, and tidy wiring to avoid interference with other components. Finally, confirm secondary wiring to the control circuits and perform a functional test.
The transformer accepts multiple primary voltages: 200/220/440 V, 208/230/460 V, and 240/480 V. It provides secondary voltages of 23/110 V, 24/115 V, or 25/120 V, with a total rating of 350 VA. It operates at 50/60 Hz and uses copper windings, making it suitable for diverse control and automation power needs in machines and panels.
