Regulated Output Voltage at ±0.50 Percent of Full Voltage Range
The SD "Quick‑Step" series unit is a positioner and regulator. It is self‑contained and consists of a stepper motor driven, microprocessor controlled, full‑range variable transformer with a 0 to 100% adjustable output voltage range. The "Quick‑Step" is shipped fully assembled, factory wired and tested, ready to be installed. The full‑range correction rate is less than one second.
The output voltage can be controlled remotely with a 1K potentiometer or a 0 to 5 volt DC process control set point signal. A single output voltage can be maintained and controlled locally with a fixed resistor network wired across the controller set point terminals. The "Quick‑Step" Variable Transformer is available in ratings of 3 to 25 amperes with output voltage ranges of either 0 to 120 volts or 0 to 140 volts. Full range output regulation is better than ± 0.50 percent. Limited output voltage range "Quick‑Step" units are available with an output regulation of better than ± 0.25 percent.
