Pioneer in the industry, we are engaged in offering an impeccable range of Variable Voltage Regulator. Use for special purpose applications and testing, the offered voltage regulators are designed under the supervision of our competent professionals utilizing superior quality material and advance technology. These are the rolling contact type voltage regulator; we are giving these regulators with various sizes as per the requirements of customers.

Features:

• Long service life
• Reliable functionality
• Robust structure

Principle of Operations:

• The Variable Voltage Supply & Regulator consist of following basic components depending on the rating of the equipment
• Step up Transformer
• Buck boost transformer
• Rolling contact type voltage regulator
• Automatic control gear

Descriptions:

• Rolling contact regulator: This is essential a continuously tapped auto wound transformer having helical coils mounted on a conventional laminated transformer core
• However, the regulating winding is designed as a single layer type giving longer and slimmer version of the transformer coil but in principal it is the same
• The regulating winding is varnished and baked to improve rigidity and ensure that the construction is non-hygroscopic
• After proper treatment longitudinal/track is ground on the coil to form a bared copper surface with the winding wire-covering providing inter turn insulation
• Graphite rollers, assembled on carrier boards, traverse throughout the length of the coil track
• These rollers are connected electrically with the output terminals and as they are driven over the track, a variable voltage is obtained
• The Regulator may be of one sided or can be made double sided
• In case of double sided Regulator both side of regulating winding is bared and allows rollers to be driven in opposite direction on either side of the coil
• In such cases carrier boards are provided on both sided of the coils and the output terminals will be taken out though balancing transformer
• The contact carrier is driven by a hand wheel / T-handle or motor, which is coupled, to the chain drive
• Limit switches operated by the carrier board are fitted to prevent over run
• In case of your specific requirement, additional limit switches will be fitted for minimum position inter-locking along with the auxiliary circuit
• The power supply of the motor is derived from the Regulator unless otherwise specified
• The entire regulator assembly is housed inside a rigid M.S. tank filled with oil
