Indoor Automatic Voltage Regulators

TSi Power’s VRP line of Automatic Voltage Regulators protects sensitive equipment.

TSi Power Indoor Automatic Voltage Regulators

TSi Power’s VRP line of automatic voltage regulators has a wide-input range and precise regulation. This indoor AVR is ideally suited to protecting sensitive equipment such as laboratory analyzers, medical imaging systems, broadcast transmitters, security scanners and CNC machine tools. The VRP is available in both single- and three-phase versions.

The VRP incorporates unique AC-chopper technology for very high efficiency and feature complete line conditioning. Its inverter imposes an ultra-fast PWM correction voltage on the primary winding of a buck-boost transformer. VRP automatic voltage regulators feature complete line conditioning. The VRP has an input voltage range of 184 to 287 V for a nominal 230 V, 50/60 Hz with output regulated to +-3%. The extended input voltage range is 160 to 330 V with reduced regulation; 120 V versions are available.

Its heavy-duty electronics and magnetics are designed to operate under worst-case conditions and incorporates industrial strength surge protection. The VRP’s efficiency is between 96 to 98% depending on operating condition. The VRP is available in single- and three-phase models, as well as in a variety of sizes.

TSi Power also produces a variety of special and custom VRP products upon request.
