Specifications of Marathon DVR2000EC AVR Automatic Voltage Regulator for Brushless
Generator
1. Directly Manufacturer
2. Over 15 years experience in generator field
3. OEM Service
Marathon DVR2000EC has the same features as the DVR2000E, however
the 2000EC has the functionality to maintain control when
paralleled with the mains utility.
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 overshoot of voltage during voltage build-up.
Engine Unloading
Monitors the rate of frequency change during transient conditions.
Provides additional voltage dip during speed drop to allow 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.
Depending on various circumstances, three different delivery
methods have been taken: by sea, by air cargo and by express

*By sea. This is the most economical way of delivery. Suit for big quantity
order, the delivery cost dramatically low and assist you in
achieving maximum profit. It normally would take about one month
for cargoes to reach their destination port.
*By air cargo. The advantage of air cargo is it costs much less time than
delivery by sea. Generally it would take about one to two weeks for
cargo reaching its destination.
*By express service. It is the most expensive way of delivery, but it is really quick
and convenient. Normally this door to door service can deliver the
goods to your company only in 3-5days. Fortunately, we have signed
big discount contract with most express companies, such as TNT, DHL
and UPS, to help our customers cut their delivery expenditure.

transfer) as the main payment method for normal orders. There are
other different payment methods which are listed below:
T/T(telegraphic transfer): For order value which is lower than 3000 USD, 100% payment need to
