The VRP is a highly sophisticated automatic precision AC voltage regulator that ensures maintenance free operation of electronic equipment over a very wide input voltage range. TSI Power's VRP series is designed to provide high precision power with industry leading response time of one-half line cycle (10 ms or less).
How the VRP works
The high frequency Insulated Gate Bi-polar Transistor (IGBT) driven converter takes the incoming AC power, measures it against the nominal voltage reference and adds or subtracts voltage to achieve a precisely regulated output. The automatic bypass will be activated when there is a fault condition. Green LED is used to indicate Normal (regulating mode) operation.
