閉合端子52J和52K之間的觸點將禁用var/功率因數(shù)控制。開路觸點使DECS-100能夠在var或功率因數(shù)模式下控制發(fā)電機無功功率。
當軟件中未啟用此功能時，觸點無效。有關(guān)更多信息，請參閱并聯(lián)發(fā)電機補償（52L/M）和電壓匹配控制選項。并聯(lián)發(fā)電機補償（52L/M）閉合端子52L和52M之間的觸點禁用并聯(lián)操作。開路觸點使并聯(lián)運行，DECS-100在無功下垂補償模式下運行。如果無功功率/功率因數(shù)控制選項存在并在軟件中啟用，則52J/K輸入具有優(yōu)先事項因此，如果52J/K和52L/M輸入均打開，則系統(tǒng)在var/power中運行因子模式。有關(guān)詳細信息，請參見電壓匹配控制選項。電壓匹配控制選項如果在軟件中啟用了電壓匹配選項，則關(guān)閉端子VM和VMC之間的觸點使DECS-100在電壓匹配模式下工作。開路觸點禁用電壓匹配。當52J/K或52L/M輸入打開時，電壓匹配也被禁用。

功率放大級
功率放大器從功率輸入級接收功率，并提供控制量的通過端子F+和F-向勵磁機磁場供電。提供給勵磁機磁場的功率為：基于從微處理器接收的選通脈沖。功率放大器使用固態(tài)功率
開關(guān)，為勵磁機磁場提供所需電源。功率放大器輸出至現(xiàn)場的額定值為：在7ADC下持續(xù)63VDC，在15ADC下保持135VDC，持續(xù)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.
