Product Details

JWintelligent purifying AC regulated power supply/three ACregulated power 300KVA

It combines purification, voltage regulator, automatic protection and anti-jamming multi-function at an organic whole, fast response speed and good output waveform, working voltage and frequency stability, high precision, strong anti-interference, resistance to impact load capacity and reliable, etc. No mechanical transmission device and no mechanical contact, thus has the advantages of long service life, low noise, no maintenance. It used in the areas of power grid voltage fluctuation is frequent, and the requirements for power supply electrical equipment of high quality

Does the product characteristics

Voltage regulator performance contrast
echnicalparameters	Precision purification stabilizer (SJC)	Dry type stabilizer (SBW) (SVC)
The working principle of	Controlled by single chip microprocessor chip and high power field effect tube or IGBT element control, depending on the bidirectional thyristor conduction Angle and form the equivalent inductance of different, make the output to the input changes to compensate for voltage stability principle	Rely on the motor drive carbon brush on the regulating transformer mobile, change the compensation voltage transformer secondary winding maintain the stability of output voltage.
features	Free maintenance, anti-jamming, high precision of voltage regulation, voltage regulation speed, can effectively inhibit the grid peak and all kinds of noise and interference, no carbon brush wear, motor drive, no spark of arc.	Regular maintenance, slow speed of voltage regulation, voltage regulation accuracy is poor, carbon brush wear and tear, motor often stuck down, easy to produce sparks coil of arc.
Pressure holding time	Fast, stable 40 milliseconds to rated voltage value, can inhibit the instantaneous surge voltage, instant effective protection precision equipment.	Slow, steady 3 ~ 5 seconds to the rated voltage value.
Voltage regulation accuracy	Peak absorption + / - 0.5 ~ 1% (dynamic)	Plus or minus 3% ~ 5% (dynamic)
Purifying function	Can filter out grid disturbance to the load, and can filter out load disturbance to the grid	No
anti-interference	Can absorb external high-energy pulse interference, inhibiting surge, clutter, spikes, etc	No
The peak absorption	Enter 3000 v / 75 us peak output 30 v or less	No
The service life of the	The average trouble-free work 100000 hours or more	The average life expectancy for 8760 hours
maintenance	Free maintenance	Regular maintenance
The noise sound	≤40dB Applicable to offices, laboratories and medical facilities	≤60dB The noise is big
The service life of the	5 to 15 years	1 year to 3 years
