A Three Phase, Phase Angle SCR Controller (1800 Amp)

• 120 - 575 V
• Protection: Current Limit, Shorted SCR Detection, Missing Cycle Detection
• Power, Current, & Voltage Feedback
• Programmability for Custom Features

A system consisting of four independent single-phase drivers.

Each driver controls, with respect to dual 0/5 Vdc setpoints, the power applied to a load by phase-angle operation of a pair back-to-back SCRs.

The 1059 is available as a Custom OEM model only. Contact the factory for more information.

A single-phase SCR controller with phase angle, zero-cross, or burst control.

The 3629B has been superseded by the 3629C, and is only manufactured as a special order. Contact the factory about availability.

The model 3629B is a three phase, six SCR, phase-angle power controller. The controller linearly controls, with respect to a command signal, either the RMS value of the load voltage or the average value of the load voltage.

3227 is available as a Custom OEM model only. Contact the factory for more information.

The model 3227 SCR power controller, linearly controls, with respect to a command signal, the electrical power applied to three-phase resistive load. It does this by zero-cross operation of silicon controlled rectifiers (SCRs) which are connected in two of the three load leads.

3027M is available as a Custom OEM model only. Contact the factory for more information.

The model 3027M is a three-phase, zero cross power controller that controls two legs of the three phase supply. The average output voltage is proportional to the command signal. Sync-Guard and Trans-Guard features are built in.

3023 is available as a Custom OEM model only. Contact the factory for more information.

The model 3023 is a 2-leg zero-cross three-phase time propor- tioning SCR power controller.

The 3023 linearly controls the power applied to a three-phase electrical load proportional to a 4-20 mA command signal by operating an inverse pair of silicon controlled rectifiers (SCRs) in a zero-cross time proportioning manner.

The 1049 is available as a Custom OEM model only. Contact the factory for more information.

The model 1049 is a single-phase, phase-angle SCR controller which linearly controls the voltage or current to a single-phase electrical load.

The command signal terminals are isolated from the line and load, and all are isolated from the heat sink.

The 1047 is available as a Custom OEM model only. Contact the factory for more information.

The model 1047 linearly controls, with respect to a com- mand or control signal, the electrical power applied to a single- phase resistive load by distributive zero-cross operation of silicon controlled rectifiers (SCRs).

The 1035 is available as a Custom OEM model only. Contact the factory for more information.

The model 1035 is a single phase, phase-angle SCR firing circuit. It controls the "ON TIME" within each electrical half cycle of two SCR's such that, depending upon the specific model number either the RMS or the AVERAGE voltage applied to an electrical load is maintained constant with respect to a control or command signal.
