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.

TSi Power’s VRX line incorporates unique AC chopper technology for very high efficiency. Its inverter imposes an ultra-fast PWM correction voltage on the primary winding of a buck-boost transformer. The VRX line of outdoor AVRs feature complete line conditioning with an input voltage range of 172 to 264 V, 50/60 Hz with output regulated to +-3%.

TSi Power's ILC Series conditioners reduce the need for a high quality ground and a dedicated line, while eliminating interference from adjacent sources of disturbances. ILC’s contribute to enhanced operation, improved repeatability, fewer reboots and system lock-ups and extended operating life.

This rugged line of isolation line conditioners is ideal for equipment located outdoors with limited or no shelter – or when the shelter is not climate controlled. They are designed for applications such as cellular base station sites, security, waste water treatment and end-of-line regulation for power utilities.

As a low-cost way to ensure maximum availability of AC power, TSi Power's automatic transfer switches enable power supply redundancy for critical loads with any combination of dual UPS, inverter backup generator or other AC power sources.

Outdoor automatic transfer switches enable power supply redundancy for critical loads with any combination of dual UPS, inverter backup generator, microgrid, or independent AC power sources.

TSi Power’s Outdoor XUPS series provides robust AC filtering, surge suppression and uninterrupted backup power for both North American and international mains power.

With an increasing trend toward DC-powered devices, DC backup is more economical than AC, because no power conversion is required in backup mode.
