PWR-TRAFO KIT This is a 25VA rated toroidal transformer. Toroidal transformers are commonly used in noise sensitive equipment or high end audio products. They are specially designed to work on all standard 115V or 230V at 50Hz or 60Hz. These transformers use heavier gauge wires than the normal requirement to avoid the copper losses during the full power output. The dielectric test is more than 3500V in between primary and secondary coils. This transformer comes with 2 rubber pads and all mounting hardware. How to mount the transformer: 1. Drill a 1/4” hole. Insert bolt. 2. Insert rubber pad/insulator. 3. Mount toroid transformer. 4. Mount 2 5. Install metal cap, washer and nut. Tighten but do not overtighten. Mains Line Wiring Guide: For 115V operation, wire the primaries in parallel (RED to RED, BLACK to BLACK). For 220V operation, wire the primaries in series, i.e. connect BLACK and RED wire together. nd rubber pad/insulator on top. Secondary Wiring Guide: - For use with the PSU-1848 PSU kit (and the PSU-2448 kit), connect the inner BLUE and GREEN wires together. Solder them to the CT pad on the PSU PCB. Also solder the GREEN and BLUE wires to AC1 and AC2 on the PSU PCB. - For use with the PSU-4448 kit, wire the inner BLUE and GREEN wires together. Insulate securely with tape or heatshrink tubing. Wire the GREEN and BLUE wire to the PSU-4448 PCB. OBSERVE HIGH VOLTAGE SAFETY AT ALL TIMES. HIGH VOLTAGE CAN KILL.
