Oil Cooled Stabilizers

Model

Model for outdoor installation

True RMS Voltage sensing for regulation
Micro controller based electronic circuit for precise correction and value added features
Measures voltage (output & input), output current & frequency
Records minimum & maximum voltage and maximum current (1 sec avg)
High performance —works for decades
Complete protection against over/under voltage, 1-phasing, overload, spikes, short circuit
High efficiency, low maintenance costs — lowest life cycle cost
