Type R Power Supply may require 14 Vdc to begin operation. Once oper-
ating, the voltage may be reduced to 12 Vdc.
Pickup Accuracy
Single Phase
PF = 1
±2 percent of front panel setting or 0.05 watts (whichever is greater).
.5<PF<1
±5 percent of front panel setting or 0.05 watts (whichever is greater).
Three Phase
PF =1
±2 percent of front panel setting or 0.15 watts (whichever is greater).
.
5<PF<1
±5 percent of front panel setting or 0.15 watts (whichever is greater).
Pickup Dropout Accuracy
95 percent of actual pickup.
Timing Adjustment Range
Instantaneous
Overpower
The overpower instantaneous response time is less than 80 ms, 60 Hz or less
than 100 ms, 50 Hz for real power magnitude of 2 times the setting and greater.
The response time is characterized by the graph in Figure 1-12.
Underpower
The underpower instantaneous response time is less than 50 ms, 60 Hz or less
than 65 ms, 50 Hz for real power magnitude of .8 times the setting and less.
The response time is characterized by the graph in Figure 1-13.
