POM SV SERIES
Range: 1 kVA to 25 kVA SINGLE PHASE. 3KVA TO 2500KVA THREE PHASE
SERVO CONTROLLED VOLTAGE STABILIZERS AIR AND OIL COOLED
The POM SV Series Servo Controlled Voltage Stabilizers are designed to
maintain stable voltage levels in various environments by addressing
issues such as load fluctuations, line failures, voltage drops, and
lightning interference. Manufactured according to IS:9815 standards, the
POM SV Series ranges from 1 kVA to 25 kVA (Single-phase) and 3 kVA to 2500
kVA (Three-phase), available in Air-cooled and Oil-cooled models. Air-cooled
stabilizers are suitable for moderate heat conditions, while oil-cooled
units are ideal for high fluctuations and heavy loads in industrial settings.
The stabilizers use a solid-state circuit and servo motor to adjust voltage
accurately, preventing overvoltage and ensuring the safe operation of
sensitive equipment. The POM SV Series SCVS is a 100% customised product
tailored to specific input and output phase and voltage requirements.
FEATURES
- Featuring fast, efficient toroidal autotransformers
for the entire capacity range. - Output accuracy better than 1%, with adjustable
precision. - Independent regulation per phase in three-phase
units, unaffected by imbalances. - The input Voltage range is customisable, with rapid
regulation speed. - Ensures stable output, unaffected by line voltage
harmonics. - Best Suits with Medical, Laser and CNC applications
