Large Power Full Automatic Compensated Voltage
DBW/SBW series large power voltage stabilizer is an energy-saving
new product developed by our company absorbing the advanced
technology of international same product,with the functions of
over/under-voltage protection,delay and error protection.It has
advantages of small volume,light weight,large capacity,high
efficiency,wide range,high precision,strong protection,without
wave-form distortion,reliable operation and easy
Widely used in the fields of post
office,store,elevator,hospital,school,publishing house and stock
exchange where normal voltage is in need,and also can be used in
the factories of large and middle-scale industrial and mining
corp.It is very much suitable for some important devices and
supporting single machine.
what's the payment term?
--We accept TT,30% deposit and 70% balance against copy of
how's the delivery time ?
--Usually it will take about 25 days for
tell me the standard of package?
--For the small capacity, it use carton, but for big capacity, we
should use strong wooden case for
what kind of material of transformer?
--We have two types, one 100% copper and the other is copper with
aluminum.It depends on your requirement. In fact,those two have no
difference if normal work well Only except the long life. Copper is
better and dearer than copper with
5.Could you offer Form A or C/O
--It totally not a problem. We can prepare relative documents to
forgin affairs office or other office to apply for this
6.Would you accept to use our logo ?
--If you have good quantity,it absolute no problem to do
7.We want to know month
--It depends on which model.For example for servo motor type small
capacity , month capacity can reach near 20000pcs and
big capacity near 3000pcs.
8.Where is your market?
A --Our products are popular in
Russia, Australia,Bangladesh, Indonesia, Pakistan, Africa countries
and so on.Some of them are our regular customers and some of them
are developing. We hope you can join us and make mutual profits
from our cooperation.
9.What is the featured products of your company
Single phase and three phase voltage stabilizers, voltage
regulator, distribution transformers, low-voltage switch gear
assembly,complete plant equipment etc.
what kind of certificate you have ?
Our company already achieve ISO, CCC, and for products, we have
Three phase four line system phase voltage:220±20%
line voltage:380V±20% or phase voltage:220±30%
line voltage:380V±30%(can be selected:Please specify when
Single phase:220V±20% or 220V±30% (can be selected:Please specify
Phase voltage:220V Single phase:220V Line voltage:380V
Output voltage accuracy
2-5%(can be adjusted)Frequency:50Hz/60Hz
≥98%(Power grade is over 50KVA)
The voltage for electrical strength and power frequency sinusoidal
is 2000V without breakdown and flash over when lasts 1 minute
It can last 1 minute at the rated current of two times
Wave form distortion
No additional waveform distortion
It offers the protections against over voltage,over current,phase
shortage and phase-sequence(the single-phase offers no protection
against the phase shortage and phase sequence)and mechanical
≤1.5S(in the condition that the ecternal voltage changes is
