RESPONSE
(Complied Or Not
Complied)
100% full copper coil single-phase AC voltage regulator, air cooling, input
145-255V AC output 220V ±4% AC
High Accuracy voltage stabilizer Power: 10kVA Input: 160-240V output:
220 -4%
High accuracy full-automatic AC voltage stabilizer;
Control system with linear integrated circuit, and drive the contact voltage
regulator to start regulating by controlling the servo motor,
Provided with delay, over-voltage, under-voltage, over-current and so on
protection function to ensure the safety of the power supply;
No waveform distortion, stable output voltage, less electric consumption
and can work continuously.
Excellent quality of output voltage, no transient electricity lost
phenomenon when the electricity supply is not interrupted, which ensure
the domestic computer and the electric appliance with memory function
can work safely and reliably.
Wide input voltage range, strong load adaptability, the 220V and 110V can
be regulated output at same time. With the over-current protection when
input, and the under-voltage, over-voltage protection when output, it can
work normally no matter attended or not.
With two indicators for input and output voltage.
Novel style, elegant appearance, hanging installed, convenient usage, with
two output choice of voltage regulating or direct output;
Nurturing Every Learner-s Potential
Users can set the voltage stabilizer in direct output state when it is in the
season of stable electric supply, the voltage stabilizer will not consume
electricity at this time, which is economic and convenient.
Suitable for families, factories, schools, industrial and mining enterprises,
research institutes, laboratories, etc.
