Contactless Voltage Stabilizer 3 Phase 50 Kva Avr Auto Voltage
Regulator
1. Product Profile
This kind of product is called contactless stabilizer, or
non-contact stabilizer. It could be three phase or single phase.
This product here is three phase one, of which the input voltage is
304V to 456V while the output voltage is 380V. Both the input
voltage and output voltage can be tailored based on your needs. The
product respond very quickly to stabilize the voltage, which only
needs less than 30ms to help voltage stabilization. Its main parts
include isolation transformers, circuit boards, silicon-controlled
modules, LCD display and other essential parts. Its output accuracy
can be customized from 1% to 3%.

About Protection Functions| Over-voltage | When output voltage is 10% more than rated one, stabilizer powers
off automatically |
| Under-voltage | When output voltage is 15% less than rated one, stabilizer powers
off automatically |
| Over Load | When output current is over the rated current, stabilizer powers
off automatically |
| Phase Dislocation | When three phase dislocates, stabilizer gives an alarm and powers
off subsequently |
| Phase Lack | When three phase voltage lacks one pahse, stabilizer gives an alarm
and powers off subsequently |
| Short Circuit | When the loading equipment is in a short circuit, stabilizer powers
off automatically |

3. Main Components and the Functions
First, isolation transformers: a three phase contactlesss
stabilizer has at least nine isolation transformers, which play an
important role in compensating the voltage for the whole circuits.
Second, circuit borads: they are advanced integrated circuits,
which features in fast speed of transmission and sound performance.
Third, Silicon-controlled modules: it helps to regulate the voltage
with no noise.
Fourth, AC Contactor: it respond quickly if it's over-voltage or
over load.
Fifth, Iron enclosure: it protects the whole parts of stabilizer,
which facilitates a longer life of stabilizer.
Lastly, there are also many small parts, which plays an significant
role in helping the stabilizer to work normally for a long time.
4. Applications
① CNC equipment
② Laser-cutting appliance
③ SMT equipment
④ Medical device
⑤ Railway stations
⑥ Subway Stations
⑦ and other places needing no-noise stabilizer.
5. Correct Operation
① Power off the stabilizer and the electrical equipment firstly.
② Connect wires according to the indications on the wiring board.
③ Turn on the power of stabilizer and the stabilizer enters into a
condition of self-checking.
④ Turn on your equipment after the input voltage is in the range of
rated input voltage.
⑤ Turn on your houshold appliance or industrial equipment in
succession.
⑥ Turn off the power if you do not use the stabilizer.
6. Detail Show
This is the LCD Display. You could see in this picture that there
are different functions of those buttons and also the input and
output voltage could be showed on the screen.
This is the switch on the back of the iron enclosure of the
stabilizer.
