JD-4D, SBW Series Power Voltage Regulator

Product Description

According to international like products and based on the situation of our country, SBW series（its model of Ministry of Information Industry is DZY series） automatic compensation type three phase power voltage regulator（hereafter referred to voltage regulator as simply）is the new generation of energy-saving type voltage regulator developed by our company.  With its ingenious design，the voltage regulator has large capacity, high efficiency, wide voltage-stabilizing scope, high precision, powerful protection function, little wave distortion, small size, light in weight, reliable operation, convenient application and maintenance and so on.  All of these are not comparable for other model voltage regulators at all. 
In contrast to like products both here and abroad， the voltage regulator produced  by our company has technical characters beyond national ministerial standards to simplify customer use as follows:  
㈠ if the voltage exceeds allowable voltage range or there is overvoltage or undertension in the output voltage of voltage regulator caused by other reasons，the products of our company provides customer-selective functions as follows:  
    a.  As for overvoltage or undertension, power cut-off and audible and visual alarm is available. after normal voltage recovery，normal power supply will recovers automatically and cancel alarm without manual operation.  
b. As for overvoltage and undertension，audible and visual alarm is sent out immediately without power cut-off to wait treatment by electricians on duty.  
    ㈡The " return middle " function in the Jingda control circuit is unique.  For example we can set the output voltage precision as 3% , and the voltage regulation is available with **8 ~ **2V. if it exceeds this scope，the voltage regulator will regulates itself. voltage regulators produced by other manufacturers will stop after this scope is realized, but as for Jingda voltage regulator, either it won't adjust or the will be adjusted to the midpoint **0V. so the movement time of electric brush will decreases much and the voltage regulator reliability is improved.  The series of voltage regulator has been adopted by electronic computer, master tool, CT, precision instrument, test set, elevator, imported equipment and process line in the fields of industrial and mining establishment, post and tele, oil field, railway, construction site, school, hospital, hotel, national defence, scientific research and so on.  Meanwhile it also is true of any locations requiring voltage stabilization as end users of low-volatile distribution with low supply voltage and large fluctuation margin and utilization equipments with large load fluctuation( such as elevator, crane, agitator) and so on.
