Automatic Voltage Controller
A high-precision servo voltage controller that maintains a stable output voltage even under wide input fluctuation, extending the life of motors, drives, transformers and electronic loads.
Engineering highlights
- Servo motor with high-grade carbon brush assembly
- CRGO laminated buck/boost transformer
- Microcontroller-based AVR card
- Bypass and overload protection built in
Typical applications
- Textile mills with motor-heavy loads
- CNC machining and engineering shops
- Pharma and food-processing plants
- Commercial buildings with sensitive electronics
Plant-level benefits
- Reduces equipment failures from voltage fluctuation
- Lowers running cost by stabilising output to optimum voltage
- Extends motor and transformer life significantly
Guarantee covers
- Manufacturing defects in the CRGO buck/boost transformer, core and windings
- Servo motor, gear assembly, and first set of carbon brushes
- Microcontroller-based AVR control card and sensing electronics
- Internal wiring, bus links, and factory-fitted protection devices
- Free labour on all in-works repairs during the 5-year term
Exclusions & how to claim
- • Damage from lightning strikes, surges, or grid transients beyond rated withstand
- • Operation outside nameplate voltage window, phase sequence, or overload rating
- • Unauthorised repairs, modifications, or tampering with factory seals
- • Physical, water, fire, rodent, or chemical-ingress damage at site
- • Routine consumables (carbon brushes) beyond the first free replacement
- • Freight to and from works for on-site failures caused by site conditions
WhatsApp the unit serial number, purchase invoice, and a short fault description with photos to +91 9422929510 or +91 9423777810 (or email activepowercontrol9@gmail.com). An engineer responds within 24 hours; once the claim is validated we arrange in-works or on-site repair with covered parts and labour at no cost.
