SCR Voltage Rating:
50-750 Amp Frames: Peak forward and reverse voltage rating 1600V.
1000 Amp Frame:
Peak forward and reverse voltage rating 1800V.
SCR DV/DT Rating:
200 volts/usec minimum.
Loads:
Resistive, Variable resistance, Inductive, Capacitive, Transformer or Lamps.
Slew Rate:
200 milli-seconds. (Slew rate is the time required for the load voltage to change 63%
of the value represented by the command signal. The current limit action will change
the slew rate if the load current is greater than the current rating of the SCRs.
Frame Size:
The "(Amps)A" term within the model number specifies the maximum continuous
RMS current rating at the maximum operating ambient temperature of 55°C.
