所述DVR2000E在一个密封封装设计背后的面板安装供给。 该DVR2000E是到位螺纹成型螺钉旋入其塑料外壳举行。 前面板指示灯（LED）告示调节状态和系统的条件。 DVR2000E连接是通过四分之一英寸制成，快速连接端子的后面板上。 后面板上的9针DB-9型连接器提供了DVR2000E和IBM兼容PC机之间的通信。

当DVR2000E稳压器被安装在发电机在工厂的成型盖设置。

该盖允许系统遵守了UL 508作为带电端子和散热器可能会暴露在意外接触。 正如该盖必须安装每当电压调节器被激励。

特征

DVR2000E单位有以下特点和功能。

•四种控制方式：自动稳压（AVR），手动或？ 场电流调节（FCR），功率因数（PF）的规定，无功功率（VAR）的规定。

•可编程稳定设置。

•具有可调时间AVR控制模式设置软启动控制。

•过励磁（OEL）的AVR，VAR和PF控制模式限制。

•低频率（伏特/赫兹）的规定。

•撬棒电路保护的视场。

•过温保护。

•三相或单相发电机电压（RMS）感应/调节AVR模式。

•单相发电机电流检测计量和调控的目的。

•磁场电流和磁场电压检测。

•四个接触感应输入的系统接口。

•一个共同的输出继电器报警指示和跳闸功能。

•六个保护功能（过励磁关闭，发电机过压关断，DVR过热停机，发电机感应停机损失，过励磁限制和撬棍关机）。

•发电机并联同功下垂补偿和无功差补偿。

•前面板人机界面（HMI）指示系统和DVR2000E状态，并给出使前面板设置变化的能力。

•使用马拉松DVR2000E- COMS基于Windows的软件，可快速，用户界面​​友好，设置和控制个人电脑通讯背板的RS-232通讯口。

The DVR2000E is supplied in an encapsulated package designed for behind-the-panel mounting. The DVR2000E is held in place by thread-forming screws that thread into its plastic shell. Front panel indicators (LEDs) annunciate regulator status and system conditions. DVR2000E connections are made through quarter-inch, quick-connect terminals on the rear panel. A 9-pin DB-9 type connector on the rear panel provides communication between the DVR2000E and an IBM compatible PC.

When the DVR2000E Voltage regulator is mounted on the generator at the factory a molded cover is provided.

This cover allows the system to be in compliance with UL 508 as live terminals and heatsinks could be exposed to unintentional contact. As stated this cover must be installed whenever the voltage regulator is energized.

FEATURES

DVR2000E units have the following features and capabilities.

• Four control modes: automatic voltage regulation (AVR) , manual or ? eld current regulation (FCR) , power factor (PF) regulation, and reactive power (VAR) regulation.

• Programmable stability settings.

• Soft start control with an adjustable time setting in AVR control mode.

• Overexcitation (OEL) limiting in AVR, VAR, and PF control modes.

• Underfrequency (volts/ hertz) regulation.

• Crowbar circuitry protects the ?eld.

• Overtemperature protection.

• Three-phase or single-phase generator voltage (RMS) sensing/ regulation in AVR mode.

• Single-phase generator current sensing for metering and regulation purposes.

• Field current and field voltage sensing.

• Four contact sensing inputs for system interface.

• One common output relay for alarm indication and trip functions.

• Six protection functions (overexcitation shutdown, generator overvoltage shutdown, DVR overtemperature shutdown, loss of generator sensing shutdown, overexcitation limiting and crowbar shutdown) .

• Generator paralleling with reactive droop compensation and reactive differential compensation.

• Front-panel human-machine interface (HMI) indicates system and DVR2000E status and gives the ability to make setting changes at the front panel.

• Rear RS-232 communication port for personal computer communication using MARATHON-DVR2000E- COMS Windows based software for fast, user-friendly, setup and control.
