| FUSION Single Phase | One | Phase Angle or Zero Cross | 24-600 Vac, 45-65 Hz (Auto-Ranging) |
50 - 1200 Amps | The FUSION single phase AC power controller is a phase angle or zero cross fired controller which linearly controls, with respect to the setpoint, the AC voltage, current, or true power applied to an electrical load. Control is achieved by means of a pair of inverse parallel SCR’s. |

| FUSION Three Phase | Phase Angle or Zero Cross | 24 - 600 Vac, 45 - 65 Hz (Auto-Ranging) |
50 - 1200 Amps | The FUSION three phase ac power controller is a phase angle or zero cross fired controller which linearly controls, with respect to the setpoint, the AC voltage, current, or true power applied to a three phase electrical load. The 3 phase controller can be ordered in either 2 or 3 leg control with 2 leg being limited to zero cross firing. Control is achieved for 3 leg by three pairs of inverse parallel SCR’s or in 2 leg by 2 pairs of inverse parallel SCR’s. | |
