A wide input range Precision PWM Line Conditioner with precise regulation, TSi Power’s outdoor VRp is ideally suited for outdoor placements, where situations so demand due to space limitations or machinery locations. It can be used to operate computerized, microcontroller based machinery as well as any other loads in any industry. Outdoor VRp is available in three-phase versions as well as bespoke models.
TSi outdoor VRp 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. TSi VRp features complete line conditioning, viz: precise real-time voltage regulation, surge & spike control, elimination of sudden brownouts caused by voltage sags due to heavy inrush current.
Conventional AVR technologies do not have this ability of real time regulation under all conditions of fluctuation including brownouts.
TSi Outdoor VRp is designed & assembled in an all weather-proof steel cabinet & is available in 3 different fluctuation ranges as below :
+ 13% range is sufficient for most industries located in industrial zones
+ 20% range is sufficient for small industries located outside industrial zones, having poor power supply
+ 26% range is for those rare locations which suffer from severe power quality issues
All models can be factory preset for any output voltage from 215 to 240V P-N. standard machinery protections include high- low voltage cut-off, overload & short-circuit protection. LED indications are provided for status annunciation. A voltmeter with selector switch is also integral. The control PCB assembly is housed in a separately ventilated compartment & connectorized with buck-boost transformer for easy replacement.
Typical output regulation is + 1%, excluding voltmeter error. Because most CNC machines as well as other industrial loads have an operating range of up to + 10% hence your VRp will continue to operate & protect your machines over an extended input voltage range, well beyond its stated range.
Outdoor VRp’s heavy-duty electronics and magnetics are designed to operate under worst-case conditions and incorporate industrial strength surge protection. Outdoor VRp efficiency is between 95 to 98% depending on operating condition. Outdoor VRp is available as a customized product, usually in three-phase configuration. However, TSi Power can also produce a variety of special, bespoke outdoor VRp products for regular OEM’s, upon request.
Outdoor VRp’s are manufactured to customer orders, hence these can generally be made available within 6 to 8 weeks.
