DECS 100 Digital AVR Automatic Voltage Regulator DECS-100
The DECS-100 is a microprocessor-based regulation system designed to control the output of a brushless excited synchronous generator. The DECS-100 is perfect for paralleling applications where generator to generator and/or generator to utility paralleling occurs with VAR/PF control and Over- and Underexcitation Limiting. The DECS-100 offers high functionality, communications, and performance at an extremely affordable price. The DECS-100 is very rugged and offers an extremely robust mechanical design that is cURus recognized, CE compliant, and DNV certified.

±1Vdc creates a ±10% adjustment (respectively) for AVR, FCR and VAR set point.
±1Vdc creates a ±0.1PF adjustment (respectively) in the PF mode set point. (adjusts only the active regulation mode)
OUTPUTS DC Output Continuous voltage: 63Vdc Continuous current: 7.0Adc 10 second Forcing Voltage: 135Vdc (with nominal input applied) 10 second Forcing Current: 15.0Adc Minimum Field Resistance: 9 Ohms
Alarm Contact Output Dry Contact Rated: 120/240Vac - make 30A for 0.2S, carry 7A continuously, break 0.1A inductive
REGULATION ACCURACY Regulation accuracy: ±0.25% no load to full load Temperature drift: ±0.5% for a 40°C change in one hour Response time: <1 cycle to the limit of the A/D converter THD: ±0.25% for 20% THD and ±0.5% for 40% THD (distortion as seen with a 6 SCR load)
