Our voltage regulators are for applications where stable power is a requirement.
TSi AVR 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. TSi AVR features complete line conditioning, viz: precise real-time voltage regulation, surge & spike control, elimination of sudden brownouts caused by voltage sags due to heavy inrush current.
Conventional AVR technologies do not have this ability of real time regulation under all conditions of fluctuation including brownouts
TSi AVR is available in standard fluctuation range of + 20%. All models can be factory preset for any output voltage from 215 to 240V P-N. standard protections include overload & short-circuit protection. LED indications are provided for status annunciation. The control PCB assembly is connectorized for easy replacement.
Typical output regulation is + 1%, excluding voltmeter error, which makes it the ideal choice for precision electronic machines. Because many residential & office applications work satisfactorily within a wide voltage range of 200-250 Volts, for such applications our AVR continues to provide clean, usable power over a widely relaxed input fluctuation of 160-300 Volts.
VRp series AVR’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- & three-phase models, indoor & outdoor configurations.
TSi VRp series indoor AVR’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.
