闭合端子52J和52K之间的触点将禁用var/功率因数控制。开路触点使DECS-100能够在var或功率因数模式下控制发电机无功功率。
当软件中未启用此功能时，触点无效。有关更多信息，请参阅并联发电机补偿（52L/M）和电压匹配控制选项。并联发电机补偿（52L/M）闭合端子52L和52M之间的触点禁用并联操作。开路触点使并联运行，DECS-100在无功下垂补偿模式下运行。如果无功功率/功率因数控制选项存在并在软件中启用，则52J/K输入具有优先事项因此，如果52J/K和52L/M输入均打开，则系统在var/power中运行因子模式。有关详细信息，请参见电压匹配控制选项。电压匹配控制选项如果在软件中启用了电压匹配选项，则关闭端子VM和VMC之间的触点使DECS-100在电压匹配模式下工作。开路触点禁用电压匹配。当52J/K或52L/M输入打开时，电压匹配也被禁用。

开关，为励磁机磁场提供所需电源。功率放大器输出至现场的额定值为：在7ADC下持续63VDC，在15ADC下保持135VDC，持续10秒。If the Var/Power Factor Control option is present and is enabled in the software, the 52J/K input has priority. Therefore, if the 52J/K and the 52L/M inputs are both open, the system operates in var/power factor mode. For more information, see Voltage Matching Control Option. Voltage Matching Control Option If the Voltage Matching option is enabled in the software, closing a contact across terminals VM and VMC causes the DECS-100 to operate in the voltage matching mode. An open contact disables voltage matching. Voltage matching is also disabled when either the 52J/K or 52L/M inputs are open. RS-232 Communication Port The communication port provides the interface for user programming (setup) of the DECS-100. Connection is made to the female RS-232 (DB-9) connector with a user-supplied, standard 9-pin cable. The communication port is optically isolated and is powered from a transformer-isolated supply. Microprocessor The microprocessor is the heart of the DECS-100 and performs measurement, computation, control, and communication functions by the use of its embedded programming and the nonvolatile settings stored in its memory. Power Input Stage Input power applied to terminals 3, 4, and 5 is rectified and filtered before being applied to the power amplifier and the power supply. Input power may be single-phase or three-phase in the range of 88 to 250 Vac at a frequency of 50 to 400 hertz. The input power source should be properly fused for the application. Power Supply The internal switch-mode power supply receives power from the power input stage and supplies power at the required dc voltage levels to the internal circuitry of the DECS-100. Power Amplifier Stage The power amplifier receives power from the power input stage and supplies a controlled amount of power to the exciter field via terminals F+ and F–. The amount of power supplied to the exciter field is based on gating pulses received from the microprocessor. The power amplifier uses a solid state power switch to provide the required power to the exciter field. Power amplifier output to the field is rated up to 63 Vdc at 7 Adc continuous and 135 Vdc at 15 Adc for 10 seconds.
