Static Voltage Stabilizers

Faith Products are recommended by leading Consultants and Contractors

The high frequency insulated gate bi-polar transistor (IGBT) driven converter takes the incoming ac power, measures against the nominal voltage and adds or subtracts voltage , 20,000 times per second, to achieve precisely regulated 230 vac output.

The automatic bypass will be activated when there is a fault condition. Green LEDs are used to indicate Normal (regulating mode) operation.

Designed with fully solid state components to govern regulation, no moving part or tapchanging mechanism (relay / static device).

Automatic Static Voltage Stabilizers, TSi Power

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.
