1029D Single Phase Power Controller

The model 1029D is a single phase, phase-angle SCR power controller. The controller linearly controls, with respect to a command signal, either the RMS value of the load voltage, the average value of the load voltage, the RMS load current or load power. The controller can be configured to accept all standard industrial command signals as well as many non-standard commands.

The model 1029D is available with current ratings from 50 to 750A, and nominal voltage ratings from 120 to 575 VAC. The controller will operate without adjustment or modification on 50 or 60 Hz. 1000 and 2000A units, although not UL listed, are available, consult factory. The model 1029D is intended for controlling transformer coupled loads, fast responding loads, and non-linear loads such as tungsten, silicon carbide, and molybdenum disilicide.

Note that 1029D has superseded 1029C.

Some features include:

• Line voltage compensation holds load voltage constant with changes in line voltage
• Soft-start for transformer loads.
• Missing cycle detection.
• Can be used with all load types.
• Thermostatically protected.
• Metering outputs representing both load current and load voltage.
• Compact and economical
• 2500 Vac RMS isolation between input/output and line voltage/heatsink.
• Natural convection and forced air cooled.
