Servo Voltage Regulators are RISC microprocessor controlled devices. The microprocessor controlled PWM technology prevents the unnecessary movements of servo motor and the variable transformer. Due to its mechanical architecture there are no tap changes providing perfect instant current reaction and output voltage sensitivity. This brings low risk of break downs, long lasting operation and low maintenance.
LOW OUTPUT VOLTAGE TOLERANCE
Servo Voltage Regulators operate mechanically at 100V/sec correction speed with low output voltage tolerance as low as ±1 %. Thus they are ideal solutions for protecting electronic loads. In general applications they are highly recommended for no critical loads such as lighting, and for stabilizing input voltage in buildings and factories.
ENERGY SAVING SOLUTION
The Servo Voltage Regulators are also ideal to be used in connection with generators where the network voltage is too low and fluctuation is high. Normally, a standalone generator starts operating below 200V, however a generator coupled with a Servo or Static Voltage Stabilizer kicks in below 165V since the Servo Voltage Regulator corrects the network voltage down to 165V level. Regulator’s correction capability within this margin would prevent unnecessary operation of generators and increase system’s efficiency.
