Some locations are in remote or under-developed areas, where the power is less than adequate, when available. In these areas, our customers and clients need a machine that can protect their equipment when the power is available, regardless of the power quality. Power Systems & Controls’ Series GSR is an Extended Range Automatic Voltage Regulator. The Series GSR is an extended range input AVR, protects your system against electrical brownouts, sags, surges, transients, and other electrical disturbances. This automatic voltage regulator utilizes (phase independent) solid-state microprocessor based regulation to monitor and adjust voltage as needed.

In addition to being a high speed tap change, the GSR is armed with a multi-shield computer grade isolation transformer and filter network, to remove transients and noise. The combined effect is dynamic voltage regulation with communication grade isolation, which solves 99% of electrical disturbance problems. As the use of power increases in cities/villages around the world, utility power can be compromised, which results in poor quality of power supplied to sensitive electronic equipment. The effect of unreliable power can cause irrevocable damage to expensive manufacturing equipment, resulting in lost production time and/or products.
