The HPS SpartanĀ® Line of industrial control transformers is ideally suited for general purpose, industrial and light duty loads. Designed for applications where high inrush or machine tool duty are not necessary, the HPS Spartan industrial open-style control transformer offers an efficient and economical solution. These units are well suited for HVAC applications, signal and alarm systems, motor control circuits, lighting and circuit isolation. Vacuum impregnated with polyester resin and oven cured. Coil face termination over 3000 VA or 30 A. Bolt-on mounting brackets. All terminal blocks utilize a combination slot/Phillips No.6 screw with a SEMS washer (suitable for 18 AWG to 14 AWG for solid wire and 18 AWG to 12 AWG for stranded wire). Coil face terminations utilize a 1/4-20 UNC x 0.5 inch combination slot/Phillips screw and a spring lock washer. Copper wound coils with high dielectric strength insulation.
