  • A1P--A1Z-Family

    A1Z Series Single Phase 1-Leg SCR Power Controllers

    (24)

    The A1Z (single Phase 1-leg), A3Z (3-phase, 2-leg) and A6Z (3-phase 3-leg) are proportional, zero voltage switched, single phase power controller capable of delivering 0-99% of the applied line voltage to directly connected electric heaters. 100% power factor. Almost zero harmonics. Can control every half cycle of power to heaters. 50/60 Hz. There are four field replaceable items:

    • Printed circuit board
    • Fuses
    • SCR packages
    • MOV's (Metal Oxide Varistors)
