Outdoor Automatic Voltage Regulators

Outdoor Static Voltage Regulators

TSi Elecpower offers outdoor type, VRp series Static Voltage Regulators, designed specifically to ensure smooth, uninterrupted operation of your expensive outdoor installations such as railway signalling yards& telecommunication cell sites. The outdoor AVR’s are available in three phase version as well as tailored models.

The outdoor AVRis a static device which 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, the outdoor static voltage regulator features surge and spike control along with EMI/RFI noise control.

In short, VRp series Static Voltage Regulator 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.

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

The efficiency of outdoor VRp series is 96 to 98% depending upon the usage. They are assembled in all-weather proof steel cabinets and available in 3 diverse variation ranges as given 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 series Static Voltage Regulator can be factory preset to provide any desired output voltage between 215 to 240 Volts + 1% P-N. LED display is provided for status annunciation. 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 outdoor VRp series Static Voltage Regulator is designed with heavy-duty electronics and magnetic which integrates industrial surge protection and works under the worst scenario. The product is tailor made to customer needs & the development cycle is usually within 4-6 weeks.
