    The G3PW Power Controller is a thyristor-type single-phase power controller that enables precise temperature control. It accepts a continuous proportional output of 4 to 20 mA or 1 to 5 V from a temperature controller to execute phase control or optimum cycle control.

    100% or from 100% to 0% to 0.0 to 99.9 s. Duty Setting The duty setting is used to set the rate of change from 0% to 100% of the out- put value in relation to the input value. Base-up Function The base-up function increases the output value so that the output value does not go to 0% even when the input value is 0%.

  • Page 68: Base-Up Function

    The base-up function increases the output value so that it does not become 0% even when the input value is 0%. Because the output value is held even when the input value is 0%, the heater can be preheated. This is effective for shortening the heating time when using a load for which the temperature increases slowly.

  • Page 69: Output Limits

    Output Limits Output Limits The output limit function can be used to set upper and lower limits for the out- put value. The output value is found with the following formula: Output value = Duty setting × Input value + Base-up value The output limit is set in the Output Upper Limit (OLU) and Output Lower Limit (OLL) parameters in the adjustment level, from 0.0% to 100% in each case.
