Voltage Adjustment DECS-200 regulates the generator RMS voltage from internal no-load to full load by 0.25%. It does this by leveraging digital technology to develop signal processing and precision regulation algorithms, using years of experience to manufacture tens of thousands of digital regulators. The stable DECS-200 utilizes proportional (P), integral (I) and derivative (D) stability control. The DECS-200 has 20 pre-programmed stability (PID) setting exciters for field applications. This means that Standard a stability Settings are already available for most applications/machines. The stability range of the DECS-200 allows for custom stability Settings to be used to fine-tune the stability to provide optimal custom generator transient performance. The PID selector is included in the setup software to help determine the correct PID Settings.

The DECS-200 provides customized stability and transient performance with Min/ maximum excitation limiter and var/PF controllers for additional stability adjustment. Low frequency limiter or V/Hz ratio limiter DECS-200 Optional low frequency limiter or aV/Hz ratio limiter function. The slope of the low frequency limiter can be tuned in increments of 0.1Hz to 0 to 3 times p.u. Volts /Hz, the corner frequency roll down point can be set in a range of 45 to 65Hz, in 0.1Hz increments. This adjustability allows precise matching of the operating characteristics of the DECS-200 prime mover and the load applied to the generator. The voltage/Hertz ratio limiter clamps the regulation set point to prevent the slope specified above the V/Hz level decs-200.

This feature is also useful for other potential applications where the system is damaged, such as changes in the system voltage and reducing frequency cases that exceed the V/Hz ratio. Soft start voltage accumulation Generator voltage overregulation can cause damage to the generator if the insulation system is not controlled. The DECS-200 has a soft-start feature with user-adjustable Settings to control the rate allowing the generator voltage to gradually increase. This reduces the rated generator voltage overshoot when the generator system is started. Parallel compensation The DECS-200 provides for two or more generators in parallel using reactive sag or reactive differential compensation to add an external current transformer with a secondary current of 1 or 5ac. Rated input current less than 1VA. This low load means that existing metered ct can be used without the need for a specialized ct. Set point control The DECS-200 has a means of external set point adjustment to control the mode of operation. This eliminates the need for remote or multi-point control of additional devices such as motor operating potentiometer excitation systems. Set points for operating mode can be 4-20mA or ±10 V DC from up/down contact input or auxiliary input. Auxiliary input to adjust its operating mode predetermined adjustment range. The auxiliary input may be a system stabilizer provided by another control device such as a power supply. The operation of these devices is modified to meet the specific operating characteristics and requirements of the DECS-200, allowing the machine to operate under the control of the DECS-200.

Two setpoint control methods can be implemented via the RS-232 communication port, using Windows?PC software, or via the RS-485 port using the Modbus? protocol. No matter which set point method is used (contact input, auxiliary input? Or communication with PC or PLC), the traversal rate operation mode of all modes can be adjusted independently. This means that the operator can customize the speed and “feel” to suit his/her needs.

The pre-set input DECS-200 provides additional flexibility, allowing for pre-set operating points for each mode of operation. With the contact input to the DECS-200, the operating mode is driven to an operation or adjustment level specified for the operating mode operator or user. Preinput in one of two ways to operate mode, maintenance or release. Maintenance mode prevention

Adjust the set value and turn off as long as the preset contact. Release mode allows adjustment of setpoints even though prepositions are closed. This feature allows the DECS-200 to be configured for specific system and application needs. Magnetic field current regulation working mode

The DECS-200 provides a manually operated channel called Field Current Regulation, or FCR, mode. In this mode, the DECS-200 regulates the field current phase generated by the internal PWM power supply.
