Instantaneous Voltage regulation. No Transient and Spikes, Sinewave output. A perfect answer and remedy for every electronic equipment.

The AC mains, powers the input winding which is widely separated, physically, from the isolated output winding. The input winding normally runs at very moderate flux linkage levels. The output winding exhibits an intrinsic energy storage characteristic and this energy storage operates in conjunction with the mains capacitor to produce self-generated AC flux field which is indirectly excited from the input windings.

"VOLTAMP FERRORESONANT STABILIZERS" are available in a wide Range from 50 VA to 5000 VA with load test conducted at unity power factor for all ratings. For configurations other than those mentioned here, please contact our office.

• Input Voltage 1 phase : 180V-260V. (Other choices on request)
• Line Frequency : 50 Hz.
• Output Voltage : 220/230 ± 1%.
• Efficiency : 90% (approx) under full load conditions.
• Output Wave Form : Sinosoidal.
• Wave Form Distortion : 5% (Approx) under full load conditions.
• Load power Factor : 0.75% lag to 0.9% lead.
• Ambient Temperature : -5° C to 50° C.
• Effect of Frequency : 1.6% (approx) change in output voltage for every 1% change in line frequency.

• Keep magnetic storage & display devices like Diskettes, Spools, Monitors etc. away from the STABILIZER.
• Switch ON the STABILIZER before switching ON the attached peripherals & while switching OFF, switch OFF attached peripherals first and then the STABILIZER.
• Avoid using the STABILIZER for high inductive loads.
• Check frequency before using the STABILIZER with a generator. Recommended frequency: 50± 1Hz.
• Switch OFF the STABILIZER when not in use.

• Output regulation: etter than 2% for input voltage variations from no load to full load.
• Current limit capacity : Inherent and instantaneous. Output voltage drops when load current exceeds the nominal value and automatically returns to normal voltage when overload is removed. Maximum output current is automatically limited to twice the nominal value under output short circuit conditions and hence, input power is limited to less to less than 10% of the nominal power. C.V.T. protects itself from higher load currents and also protects loads by dropping output voltage.
• Spike suppression: Inherent and high. 2000 volts spike at input is suppressed to 1 volt at output.
• Isolation: Very high. More than 100 mega ohms between input and output.
• Voltage stabilization response time: 10 - 20 milliseconds.
• Noise rejection capacity : Very high. High isolation between input and output, removes high frequency components of the transverse mode noise. Neutral to ground bonding on the secondary side causes short circuit for common mode noise.
• Short interruptions and dips handling capacity :Very high. Output voltage remains continuously available even up to 3 milliseconds of non availability of input voltage.
• Full load efficiency : Better than 87% .
• Frequency variation effects: 1% change in frequency causes 1.6% change in output voltage.
• No load loss: 15 - 22% of rated VA capacity.
• Wave form distortion: Less than 5% .
• Recommended power factor: 0.8 to 1.
• Operating temperature range: 0 Degree Celsius to 50 Degree Celsius
• Front panel controls: Voltmeter with selector switch.
• Rear panel controls: 1. Terminal block connector for selection of output voltage. 2. Fuse for protection of C.V.T.  3. Mains cord for connection of input voltage.
• Mechanical details: Rust and corrosion proof powder coated CRCA enclosures.
