Servo Voltage Stabilizer is designed to give substantially constant voltage with +/- 1% regulation without causing harmonic distortion.

It essentially employs a Solid state circuit which controls the Servo Motor. The Motor is coupled to the arm of a continously variable transformer which feeds to the primary of a series control Buck- Boost transformer.

Voltages Stabilizers are manufactured under stringent quality control and careful supervision using best raw material in various types for varied applications.

The main transformer in them has computer aided Design to give high efficiency and minimum iron loss resulting in low heat generation and saving in electricity.

Digital Voltage Corrector is Fully Micro-Processer Controlled with computer aided Low Energy Loss Torroidal Transformer having all necessary protections and is tailor made to suit the requirements of ACs. It has a built-in TIMER to give Delay Start to AC's compressor.

Constant Voltage Transformer works on Ferroresonance principle to give you constant voltage, over a wide range of input supply voltage. Because of high isolation between input and output CVT provides protection against spikes, transients and harmonics.

CVT'S offer very high system reliability, a prerequisite for high cost applications.

CREST UPS is designed with advance mosfets and latest power switching technology employing excellant line filter. Every unit is manufactured under careful supervision and stringent quality control to ensure extra uptime for your computer system.

Power Inverter provides instantaneous standby power in the event of mains supply failure and is extremely useful for domestic and office requirements. Carefully designed with latest built in features using best available components CREST inverter gives reliable and trouble free service over a long time.

Customised Servo is specially developed for photocopier machines. It has two transformers but no servo motor therefore no wear & tear.

It however provides complete protection to machines against low or high voltage.

Isolation Transformer are effective for isolating sensitive equipment from voltage transient, spikes, noises and DC leakage ect. They are specially designed for sensitive equipment and preventive such disturbance generated by the noisy equipment, load from being injected into the power line. The multiple shielding technique employed in isolation transformers reduces the inter winding capacitance to a level below 0.005 picofarad and increases DC isolation to over 1000 M ohms. Isolation Transformer provides electrostatic shielding, attenuate common mode noises and minimize transverse mode noises. Three single phase isolation transformer, may be connected in star configuration to get three phase isolation transformers. Isolation transformer can also be used for voltage conversions of 230 to 230 Volts, 110 to 115 Volts, 230 to 115 Volts or 115 to 230 Volts AC

Every electrical apparaus or machine is provided with insulation between live part and earth or between two or between two different sections of live parts. This insulation is required to be tested at high voltage values recommended by applicable relevant standards.              The standard specification for various electrical apparatus specifies power frequency voltage withstand test at different levels depending upon working voltage of electrical apparatus. It is observed from the various standards for electrical equipments that the minimum power frequency voltage withstand test levelfor electrical insulation is 2 KV for one minute.
