DVR2000E, MARATHON, AVR, Electric Voltage Regulators
True RMS Sensing ± One or Three Phase:
Connect the sensing mode you prefer. Senses 95 to 600 volts ±10% at 50/60 hertz. Patented circuitry senses true RMS voltage rather than average for superior load regulation.
Soft-Start Ramp on Initial Start-Up:
Controlled increase to rated voltage. Limits the overshoot of voltage during voltage build-up.
Engine Unloading:
Monitors the rate of frequency change during transient conditions. It provides additional voltage dip during speed drop to allow the engine to recover faster.
Overvoltage Shutdown:
Provides generator protection during sustained overvoltage. The overvoltage point is preset at 20% over normal generator operating voltage, with a preset timeout of 0.75 seconds.
VAR/PF Controller:
Model DVR 2000EC (optional) provides control when paralleled to utility power. VAR or PF control can be selected or changed by regulator adjustment.
Encapsulated Design:
Maximum protection against moisture or abrasive contamination, which can lead to early regulator failure.
Tested to MIL-STD-705, Method 711.1C. Salt fog tested to MIL-STD-810E.
Auto/Manual Mode:
Exciter field current can be controlled by the regulator or manually set at a fixed value.
