Three Phase SCR Controllers
|Model||Phases||Firing Mode||Output||Current Low||Current High||Highlights|
Powered off of the 4/20mA loop, so no control transformer is required.
|3021A||Three Phase||Zero Cross||AC||10||70||
Accepts most commands.
|3021B||Three Phase||Zero Cross||AC||10||70||
Accepts most commands. Sync-guard smoothes out line current draw when multiple controllers are in use.
|3027||Three Phase||Zero Cross||AC||85||750|
|3037||Three Phase||Zero Cross||AC||85||750|
|3337||Three Phase||Zero Cross||AC||200||750|
|3629C||Three Phase||Phase Angle||AC||50||1000|
|3869||Three Phase||Phase Angle||DC||300||400||
Accepts most commands. High current, three phase DC output.
|Compact FUSION Three Phase||Three Phase||Phase Angle, Zero Cross, Burst||AC||10||160||
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.
|FUSION Three Phase AC||Three Phase||Phase Angle, Zero Cross, Burst||AC||50||1200||
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 SCRs or in 2 leg by 2 pairs of inverse parallel SCRs.
|FUSION Three Phase DC||Three Phase||Phase Angle, Zero Cross, Burst||DC||60||1400||
The FUSION three phase DC power controller is 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.
