Fusion - DC, Phase Angle - Zero Cross - Burst, Three Phase SCR Controller FUSION Three Phase (DC) Power Controller Three phase Phase angle DC 60 - 1400 Amps

24 - 600 Vac. A microprocessor-based DC SCR controller operating both analog and digital interfaces. A phase angle-fired controller which linearly controls, with respect to the setpoint, the DC voltage, current, or true power applied to an electrical load. Control is achieved by means of a six SCR bridge with freewheeling diode.

Fusion - AC, Phase Angle - Zero Cross - Burst, Three Phase SCR Controller FUSION Three Phase (AC) Power Controller Three phase Phase angle, Zero cross, Burst AC 50 - 1200 Amps

24 - 600 Vac. A microprocessor-based SCR controller operating both analog and digital interfaces. A phase angle or zero cross fired SCR 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 SCRs or in 2 leg by 2 pairs of inverse parallel SCRs.

Fusion - DC, Phase Angle - Zero Cross - Burst, Single Phase SCR Controller FUSION Single Phase (DC) Power Controller Single phase Phase angle DC 45 - 1080 Amps

24 - 600 Vac. A microprocessor-based DC SCR controller operating both analog and digital interfaces. A phase angle fired controller which linearly controls, with respect to the setpoint, the DC voltage, current, or true power applied to an electrical load. Control is achieved by means of a half controlled SCR bridge.
