The following modes are used to regulate the CGCM unit.
!62/PERATING-ODE
•
Accuracy: ±0.25% over the load range at rated power factor and constant
generator frequency.
•
Steady State Stability: ±0.1% at constant load and generator frequency.
•
Temperature Drift: The maximum error due to temperature drift will be
0.005% of full scale per degrees Celsius for voltage and current
measurements and 0.010% of full scale per degree Celsius for watt and
VAR measurements.
•
V/Hz Characteristic: Slope from 0 to 3PU is adjustable in 0.1PU
increments. Two knees and two slopes are available.
•
Response Time: < 1 cycle.
&#2/PERATING-ODE
•
Accuracy: ±1% of rated current.
6!2/PERATING-ODE
•
Accuracy: ±0.4% of the nominal VA rating at the rated frequency.
0OWER&ACTOR-ODE
•
Accuracy: ±0.02% of the PF setpoint for the real power between
10…100% at the rated frequency.
