Single Phase SCR Power Controllers
|Model||Phases||Firing Mode||Output||Current Low||Current High||Highlights|
|1020||Single Phase||Zero Cross||AC||10||70||
Powered off of the 4/20mA loop, so no control transformer is required.
|1021A||Single Phase||Zero Cross||AC||10||70||
Accepts most commands.
|1021B||Single Phase||Zero Cross||AC||10||70||
Accepts most commands. Sync-guard smoothes out line current draw when multiple controllers are in use.
|1022||Single Phase||Phase Angle||AC||10||70||
Accepts Vdc and potentiometer commands.
|1025||Single Phase||Phase Angle||AC||10||70||
Accepts mA commands.
|1027A||Single Phase||Zero Cross||AC||50||160||
Accepts most commands. Features include: Sync-guard and Trans-guard.
|1029D||Single Phase||Phase Angle||AC||50||2000||
Higher current ratings than our solid state relay models. Features include: current limiting, shorted SCR detection, over-current trip, metering outputs, user selectable feedback modes.
|1032A||Single Phase||Phase Angle||AC||10||70||
Accepts most commands. Field adjustable current limiting.
Single or Three Phase
|Phase Angle or Zero Cross||AC||10||70||
Multi-zone. Accepts most commands. Allows mixing of line voltages and load currents for multiple zones in a small footprint.
|1802/1805||Single Phase||Phase Angle||DC||10||40||
60Hz halfwave DC output. 1802 accepts Vdc or potentiometer commands, 1805 accepts mA commands.
|1822||Single Phase||Phase Angle||DC||10||30||
Accepts Vdc or potentiometer commands. 120Hz fullwave DC output.
|1825||Single Phase||Phase Angle||DC||10||30||
Accepts mA commands. 120Hz fullwave DC output.
|2022||Single Phase||Phase Angle||AC||10||70||
Accepts most commands. Dual setpoints for fast transitions.
|Compact FUSION Single Phase||Single Phase||Phase Angle, Zero Cross, Burst||AC||10||160||
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 Single Phase AC||Single Phase||Phase Angle, Zero Cross, Burst||AC||50||1200||
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 SCRs.
|FUSION Single Phase DC||Single Phase||Phase Angle, Zero Cross, Burst||DC||45||1080||
The FUSION single 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 half controlled SCR bridge.
