TSI-VRP assures seamless operation of electronic machines by providing purest power through continuous pulse width modulation (PWM) switching of a buck-boost transformer using a convertor engine .

• The high frequency Insulated gate bi-polar transistor (IGBT) driven converter engine takes the incoming ac power, measures against the nominal voltage and adds or subtracts voltage. 20,000 times per second, to achieve real-time compensation of voltage disturbances, sag or swell. All this is achieved within 20 milliseconds through seamless PWM compensation of voltage so that all voltage disturbances are corrected within ITIC curve for flawless operation of electronics. 

Key VRP Technology Features And Consumer Benefits :

• Since the VRP technology controls any sag or swell cycle within 20 milliseconds ,it is the ideal voltage conditioner for your sensitive electronic devices.
• Since the VRP has in-built spike and noise controtit eliminates the need of additional spike & nose filters.
• Since the VRP does not switch components in the power path , it is compatible with most loads including regenerative loads.
• AC input circuit breakers prevent costly equipment damage due to load side faults.
• Automatic bypass circuitry assures fail safe operation .
• Light weight and compact size makes for ease of installation.
• Static technology results in quiet operation, high product up-time & low maintenance.

NPS VRP is a cost-effective three phase automatic precision AC voltage regulator that ensures maintenance-free operation of electronic equipment over a wide range of input voltage range without having the need of an input neutral for carrying out its operation. TSi-NPS VRP series is designed to provide high precision power with a typical compensation time of 20 milliseconds to comply with the requirements of the ITIC curve for power supply to electronics.

How the NPS VRP works:

The high frequency Insulated Gate Bipolar Transistor (IGBT) driven converter takes the incoming AC power, measures it against the nominal voltage reference and then adds or subtracts a compensating voltage to achieve a precisely regulated 400 V output.

Key Features and Benefits:

·      NPS VRP doesn't need input neutral.

·      Ability to provide healthy output even if there is a break/failure of incoming neutral.

·      Provides the output voltage within +/-1% of the nominal voltage with real-time optimum voltage compensation, as well as spike & noise control.

·      Output load can be single phase as well as three phase.

·      No change in wiring is required. Input will be three phase 4 wire and output will be three phase 5 wire.

·      Static technology results in quiet operation, high product up-time & low maintenance.

·      Internal surge voltage protection assures trouble-free operation.

·      AC input circuit breakers and load over current protection prevents costly equipment damage.

·      Tight control over electronic card failures, data corruption and machine breakdowns result in higher productivity, lower operating costs, and greater consumer comfort.

·      Lightweight and compact size makes for ease of installation.
