In the developing countries, especially the remote areas, the mains power is extremely unstable. And the input voltage range (especially the minimum voltage) is very wide. For
example, the low input voltage can be down to 88V (the rated line to neutral voltage is 220V) that results in the electrical equipment cannot start and operate.The common voltage stabilizer cannot handle the extreme low and unbalance voltage. Even if those can reluctantly work, the output power is de-rated a lot due to low voltage and high current
situation. A special voltage stabilizer with a step-up transformer can some how solve the problem, but it has the disadvantages of high cost, low efficiency and more space
occupation.
 
Our special designed ZDBW,ZSBW series extreme wide range voltage stabilizer adopting patent voltage regulator used to cope with input voltage down to 88V, and output voltage regulated to rated 220V without de-rated input power a lot.Its high cost effective, reliability, high performance and long lifetime are all backed by a world class organization with decades of mains power experience. It is applied for any loads like telecom, medical, industrial, commercial and household applications.
Features
•Extremely wide voltage regulation
range: 88-264Vac (L-N), or can
