VRP2000-02 VRP3000-02 VRP5000-02 Automatic Voltage Regulators/Line Conditioners

Traditional tap-switching AVR used to be considered the more heavy duty of the two voltage regulation topologies for developing country applications. Over time, the newer electronic pulse width modulation (PWM) based VRp Series has proven itself as not only the more precise methodology, useable on any kind of load, but also is now preferred for use in countries with quite aberrant power as well as those with relatively stable power, such as the US, Europe, etc.

VRp stands for voltage regulation with precision. VRp provides output voltage within plus/minus 3% of nominal, for input voltage that may vary wildly, e.g. 172 to 276 Vac instead of a stable 230 Vac. There is no switching of taps or otherwise a break in the power path thanks to continuous PWM switching of a buck-boost transformer. The VRp voltage regulator is designed for applications that require absolutely stable, high-reliability power, without switching components in the power path. The low-weight, high efficiency VRp electronic voltage regulator is easy to install in any environment. The automatic bypass assures that connected equipment will not shut down, even if the VRp fails. And if there are high inrush currents such as with the startup of motors the VRp will temporarily go to bypass to provide the necessary current to the load. VRp is compatible with all loads as it does not switch any components in the power path. VRp’s ultra-low impedance assures stability even with the most demanding loads.

The VRp Series, in 2 to 30 kW output single-phase models, and 6 to 90 kW output three-phase models, provides cycle-by-cycle voltage regulation by using 15 KHz microprocessor-controlled IGBT switching technology with 96% or higher power conversion efficiency. The extremely fast input voltage detection and correction time of 20 ms (about 50 to 200 times faster than traditional servo-motor controlled AVR and about 20 to 50 times faster than relay/triac/scr based tap-changing AVR) ensures protection of even the most sensitive and mission-critical telecom, medical, instruments and production equipment. VRp Series units provide a significant portion of a good high availability power strategy, yet are only a small fraction of the size, weight and cost of an equally sized UPS system.
