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.
VRP Single Phase 230 V
VRP single-phase units are available in following sizes: 2, 3, 5, 7.5, 10, 15 and 20 kVA and rated for 230 V at 50/60 Hz. They may also be ordered for 208, 220, and 240 V. The control PCB assembly is connectorized for easy replacement.
VRP Single Phase 120 V
VRP single-phase units are available in following sizes: 2, 3, 5, 7.5 and 10 kVA and rated for 120 V at 50 or 60 Hz. Units may also be configured for 100 V output for the Japanese market as well as 127 V for Mexico. The control PCB assembly is connectorized for easy replacement.
VRP Three Phase 230/400 V
VRP three-phase units are available in following standard sizes: 9, 15, 22.5, 30, 45, 60, 75, 90, and 105 kVA and rated for 230/400 V at 50/60 Hz. Units may also be configured for 220/380 and 240/415 V. Other sizes available on request. The control PCB assembly is connectorized for easy replacement.
VRP Three Phase 120/208 V
120/208 V three-phase VRP automatic voltage regulators are available in size from 6000 to 50000 watts. Output is 120/208 V at 50 or 60 Hz, and 100/173 V and 127/220 V are available as well. The control PCB assembly is connectorized for easy replacement. The unit is compact, lightweight, and offers mobility with lockable casters.
VRP Three Phase 480 V Wye
VRP three-phase 480V wye precision automatic voltage regulator line conditioners are available from from 9 to 100 kVA for 277/480V wye (four wires plus ground) operation (other sizes and voltage configurations available upon request). The control PCB assemblies are connectorized for easy replacement.
Rack/wall/floor mounting kits for Indoor VRPs
TSi Power’s Rack/Floor/Wall Mounting kits enable our Indoor XUPS, VRP, ATS and ARM series to be placed virtually anywhere that fits your space considerations, including on the desktop or on the floor. For rack mount configurations, the VRP is designed to accommodate most standard component rack enclosures. With a simple rack mount kit option, you can place your UPS, automatic voltage regulator or automatic transfer switch in a 19”, 23” and 24” rack to better facilitate the space requirements of your systems.
