Marathon DVR2000EC AVR Automatic Voltage Regulator for Brushless Generator

Product Specification

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.

*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.

In most situations, we accept T/T (telegraphic transfer or wire 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 be made in advance. For order value which is higher than 3000 USD, 30% deposit need to be made in advance and the balance should be transferred when cargo is ready for delivery.

Western union: western union could be accepted only when the cargo sent by express service and do not need clear the custom in China.

PayPal: only be accepted for easy buy customers who delivery the goods by express service and do not need clear the custom in China.
