About AC to AC Voltage Transformers

For single-phase equipment, use this formula to find power output: VA = Volts × Amps

For three-phase equipment, use this formula to find power output: VA = Volts × Amps × 1.73

NEMA 1-15 Plug

Power devices that require less than 120 volts AC. They can also be used to charge backup batteries.

Solenoid Valve Cords

Use these cords with hydraulic and air-powered valves, motors, pumps, and pressure switches. They have a solenoid valve socket on one end and an M12 threaded plug on the other. The ground connection is not included in the number of poles. A power-indicating light on the socket illuminates when the cord has power. All are IP-rated for protection from washdowns and temporary submersion.
