Servotech Power Systems Private Limited

With the advances in Calibuer Series Static Voltage Regulator, Power Electronics, Static Voltage Regular (SVR) has emerged as a new technology to provide ride through support for crucial facilities in the event of transient under voltage / over voltage conditions. The SVR through the use of its static tap changer regulates the voltage to its present level i.e. 220 volts+- 5%. Unlike conventional load tap changers, which are equipped to respond instantaneously by selecting the appropriate tap on a sub cycle basic, without the need to progress through a series of lower voltage tap.

The simplicity of this design results in the high efficiency & robustness if the SVR. With strategic combination of advanced power electronic and microprocessor, high performance and high correction speed of the SVR are guaranteed.

Additional Isolation Transformer & RFI/EMI filters constitute a high level spike suppression system which further protect your equipment by virtually eliminating any transients in the distribution network.
