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 Controllers 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.

Fusion-AC,Phase Angle-Zero Cross-Burst, Single Phase SCR Controllers FUSION Single Phase (AC) Power Controller Single 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 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 SCRs.

Compact Fusion - AC, Phase Angle - Zero Cross - Burst, Three Phase SCR Controll Compact FUSION Three Phase Power Controller Three phase Phase angle, Zero cross, Burst AC 10 - 160 Amps

24 - 600 Vac. A microprocessor-based SCR controller operating both analog and digital interfaces. Can be ordered in either 2 or 3 leg control with 2 leg being limited to zero cross firing. Output is controlled linearly with respect to command signal and can be set to the average or RMS value of the voltage or current, as well as true instantaneous power or external feedback.
