Indoor PWM Line Conditioners

Indoor PWM Line Conditioners

Our line conditioners are for applications where stable power is mandatory for electronically operated, microprocessor based CNC, automation & robotics machinery operations.

TSi Elecpower offers VRp Series, Indoor type, PWM Precision line Conditioners, designed specifically to ensure smooth, uninterrupted operation of your expensive modern power electronics / microcontroller based machines in industries as diverse as telecom, television, server-rooms, robotics, automation, process-control, textiles, packaging, printing, plastics, steel, scientific labs etc. It is available in both single-phase as well as three-phase versions.

VRp Series integrates a revolutionary AC-chopper technology. It uses a dynamic response, high efficiency converter engine, which superimposes a high speed PWM correction voltage waveform on the incoming waveform, through a specially designed buck-boost transformer. In addition, VRp line conditioner features surge and spike control along with EMI/RFI noise control.

In short, VRp Precision Line Conditioner provides complete line conditioning via-dynamic voltage regulation of surges, sags & brown-outs, elimination of spikes, electrical noises & real-time voltage regulation. Because there is no switching or break in the power path, hence it can handle all types of loads with equal ease.

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 TSi- VRp models can be factory preset to provide any desired output voltage between 215 to 240 Volts +1% P-N. Standard machinery protections include high & low voltage cut-off, overload & short-circuit protection. All standard machinery models are provided with a digital voltmeter with selector switch. For ease of replacement, the surge cards and control PCB assemblies are connectorized.

Generally output voltage regulation is +1%, excluding any voltmeter error. Since most of the CNC machines and other industrial loads have a functional range of up to +10% hence VRp will keep on operating your machines over a much wider input voltage range, well beyond its designed range.

The VRp series units are designed with heavy-duty electronics and magnetics to keep working even under extreme conditions at their outer design limits.

TSi- VRp has been highly standardized for performance reliability and fast delivery. The listed standard models are available as ex-stock or, maximum within 2 weeks’ time. Besides standard models, TSi Elecpower can also offer special, rack-mounted and bespoke VRp products as per the prerequisites of OEM’s. Kindly ask for an offer.
