DBW5B/SBW5B series Non-contact Compensatory voltage stabilizer is our patent product developed since 1997. Acknowledged by the Academia Chinese information center, this product’s many technologies are unique in the industry. Its overall technology had achieved the international similar products’ advanced level. It fills the gap of the domestic non-contact regulator. SBW5B series non-contact Non-contact Compensatory voltage stabilizer adopts the electric power electronic technology, is a new generation product of traditional DBW/SBW Non-contact Compensatory voltage stabilizer. Compared with the similar product, the technological is advanced, the function is complete. Its capacity is able to achieve 2000KVA the compensation range may reach ±50%, the efficiency is above 99% adopting our patent technology. It has no pollution to the electrical network. It has well Compatibility, can be used in each kind of bad electrical network and in the complex load situation with continuously steady work, which exempts maintenance for more than 10,000 hours without malfunction.
The Non-contact Compensatory voltage stabilizeris being on sale in our company at present is already the fifth dynasties promotion product. Its main characteristic are:
1.The voltage adjustment is quick, adjust the voltage in 40ms 2.No audible noise when running, the efficiency may achieve above 99% 3.No distort harmonic wave, no instantaneous power failure 4.Separate three-phase adjustment. When worked in low voltage, it can be equipped with full load 5.High precision, it may reach ±2~3％ 6.The remote monitor, JOSLYN brand surge protector and power source filter, voltage input selection mechanism, automatically by-pass mechanism and multiple output switch could be equipped to meet need. 7.The cabinet could be designed according to customer.

Main function:
Power on way
The stabilizer is equipped with automatically or by manual two ways to power on for the user’s choice. It is in automatic way when left from factory.
Time delay output
The stabilizer will put out energy in 3~5 seconds (short time delay) or 3~5 minutes (long time delay) when powered on, to protect the electric appliance from the shocking damage
Over-voltage, low-voltage protection
When the input phase voltage surpasses ±10% of the compensation range, the stabilizer sends out the acousto-optics to report, and shuts off the output power source
Breakdown protection
When the stabilizer is damaged and can’t work normally, it will automatically turnoff output power source.
Short circuit protection
When the output happens to short circuit situation, the air-switch will automatically turn off input power source.
Lack phase protection
When the three-phase input happens to phase-lacked, the stabilizer will shut off output power source automatically
Automatic, manual bypass
When the stabilizer happens to breakdown, it can be turned to bypass automatically or by manual
Thunder and lightning surge protection
The stabilizer is equipped with 20KA surge protection device when left from factory. The world first brand JONSLY is optional
Alarm or silencing function
The stabilizer is equipped with alarm or silencing choice button
Phase order protection(optional)
When the input phase order is abnormal, the stabilizer will shut off output power source
The main circuit filter function (optional)
May install the PD series model filter in the main circuit according to the user
Type solution guide:
·According to the electricity net, choose the input scope of stabilizer. ·According to the load admitted input voltage, choose the precision of stabilizer. ·According to the load capacity, load power fact and load nature, choose the capacity of stabilizer ·For the ordinal AC equipment, the power factor suppose to be computed according to 0.7, for sensitive load (elevator, electric welding machine and so on) must consider the starting current. ·The non-linear equipment (frequency conversion equipment, UPS and so on), the electric current suppose to be computed according to 2~2.5 times. ·According to the local thunderstorm day index, may install the thunder and lightning surge protector and the filter in the cabinet; If users’ request is not included in the instruction, it can be treated as special order to design and produce.
