Servo Voltage Stabilizer:
UNITOP Servo Voltage Stablizer
essentially employs a solid state circuit which controls the Servo
Motor. The Motor is mechanically coupled to the arm of a continuously
variable auto transformer which feeds the primary of a series control
buck-boost transformer. The output voltage of the stabilizer is
compared with reference voltage and the resultant error signal controls
the Servo Motor providing the required output voltage-thereby providing
a true propotional control system rather than on/off circuit.
Features:
- Fully Solid State Control Circuit.
- No Wave-Form Distortion.
- Better accuracy-adjustable from .5 % to 5 % of set voltage.
- High Efficiency.
- Auto-Manual Operation facility.
- On-line serviceability through interchangeable plug-in control card.
- Stepless voltage correction of high speed without over shoot.
Optional Features:
- High and Low Voltage Protection.
- Overload protection.
- Extended input range-any voltage range between 90V - 280 V per phase.
- Single Phasing Protection for Three Phase Units.
- Spike Suppressor.
- Isolation Transformer.
- Digital Volt/Amp. Meter.
