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 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 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 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 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.
Compact FUSION - Single Phase Power Controller	Single phase	Phase angle, Zero cross, Burst	AC	10 - 160 Amps	24 - 600 Vac. A microprocessor-based SCR controller, operating with both analog and digital interfaces. 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.
