Features:
- For North America
- Standby operation minimizes interaction with existing loads or power distribution systems while being compatible with most loads
- A wide input range (±20%) and precise output regulation (±3%) provide superior performance.
- Various AC input/output connector-type wiring terminals facilitate specific applications.
- Internal surge protection and noise filtering assure trouble-free operation.
- AC input circuit breakers and load over-current protection prevent costly equipment damage.
- Customizable for unique and challenging applications.
The VRP is a highly sophisticated automatic precision AC voltage regulator that ensures the 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 an 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 rated output voltage. The automatic bypass will be activated when there is a fault condition. Green LEDs are used to indicate Normal (regulating mode) operation.
