A wide input range PWM Line Conditioner with precise regulation, TSi Power’s VRp is intended for indoor installation. It is ideally suited to operate & protect your sensitive, computerized, microcontroller based machinery in industries as diverse as machine tools, robotics, automation, textiles, newspapers & printing, steel, plastics & process-control. VRp is available in both single- and three-phase versions.

 

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. VRp Precision Line Conditioner features complete line conditioning, viz: precision voltage regulation during machine operation as well as during regenerative cycling, surge & spike control, elimination of sudden brownouts due to operation of nearby switching loads.

VRp 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. A voltmeter with selector switch is also integral. The control PCB assembly is connectorized for easy replacement.

Typical output regulation is + 1%, excluding voltmeter error. Because most CNC machines 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.

VRp’s heavy-duty electronics and magnetics are designed to operate under worst-case conditions and incorporate industrial strength surge protection. VRp efficiency is between 95 to 98% depending on operating condition. VRp
is available in single- and three-phase models, as well as in a variety of sizes.

 

TSi VRp series indoor Precision PWM Line Conditioner’s standard listed models are highly standardized for performance consistency &  fast delivery. Consequently, standard listed models can generally be made available ex-stock or, at the latest, within 2 weeks.

 

TSi Power can also produce a variety of special, rack-mounted and bespoke VRp products for OEM’s, upon request.
