SVC series high-accuracy full-automatic AC voltage regulators are our leading products, made up of contact voltage
regulator, servo motor and automatic control circuit. When the voltage of power network in not stable or when the
load changes, the automatic control circuit will sample, amplify and send signal to drive the servo motor to adjust
the position of carbon brush of contact voltage regulator, and enable the output voltage to the rated value, to get
voltage stabilization finally.
The equipment possesses visible advantages such as elegant appearance, compact design, light weight, high
efficiency, no distortion of output waveform, complete protection functions, long service, etc. For sake of the top
quality, the key electronic elements are all imported and performed quality inspection strictly.
The equipment is suitable for areas where power grid fluctuates frequently or changes greatly along the season,
widely applied to industry, scientific research, medical service, school, communication, household appliance, etc,
it can provide any loads with top power supply to ensure the power device can run normally.
The equipment complies with trade standard SB/T10266-1996 (SVC series single - phase 10kVA and below
products.

Wiring Connection
Operation instruction
1. before operating, please make sure the voltage of power network is within the range of input voltage permitted
by this equipment, then connect the wires according to the symbol on front and back panel carefully and do not
make mistake, make sure firm grounding. (Input wire of voltage regulator of single-phase 1.kVA and below is
power line, and socket is for output; please refer to diagram 6.
2. Turn on the power switch of the voltage regulator, the output voltmeter of single-phase voltage regulator shall
indicate to 230V check if there is phase failure; only when it is normal voltage regulating that
you can turn on the power switch of consumer.
3. When single - phase voltage regulator outputs 230V and 230V at the same time, the sum of load current can't
exceed the rated value.
4. When it is inductive load (such as air-conditioner and refrigerator), as the starting current of inductive load is
very heavy, please choose voltage regulator whose output capacity is 3-5 times of load power. for other
capacitive and impactive loads, please leave enough allowance for output capacity of voltage regulator.
5. When the mains voltage is rather normal, please use the commercial power, at this time, the voltage regulator
does not have power loss. Open the voltage regulation circuit breaker, and close commercial power circuit breaker.
6. When mains failure happens (include loss of phase) or the input voltage is too high, please turn off the voltage
regulator and the power switch of consumer in time.

Attentions
1, Please place the voltage regulator in a draughty environment where is no corrosive gas, explosive gas, conductive
dust or steam, and the children can't touch it, besides, it mustn't subject to the sunshine or rain.
2. The earth terminal must be firm and reliable to ensure safety.
3. The voltage regulator will produce little heat when it works normally, it is not allowed to cover with any things,
otherwise, it would be damaged for not sufficient heat emission.
4. The fluctuation of external voltage that leads the equipment regulates the voltage automatically, it is normal that
there is the friction sound trom gear.
5. Choose input and output leads with suitable sectional area according to the power of voltage regulator, try to
reduce power consumption in the circuit in general, 5A/mm' for copperwire, and reduce half for aluminum wire.
6. The earth wire and neutral wire shall not be connected inversely and the earth wire can't take the place of neutral
wire, otherwise, it wouid cause the equipment body produces electricity or it cant work normally
7. When the voltage regulator is energized, it is forbidden to open the case for adjusting randomly, in order to prevent
the electric shock.
8. In case that the frequency of generation power grid is unstable, but the electricity is needed urgently, user can use
the function of directly providing commercial power, to protect the equipment against damage for unstable
frequency.
9. When the equipment has been used for a long time, a professional clectric worker ahall be invited to clear away
the dust in the machine regularly to keep the clean between carbon brush and coil grinding surface and adjust the
contact pressure between them to get a fine contact against flashover, if thecarbon brush is worn seriously, please
change it in time, to prevent the equipment being damaged.
10. If the equipment works abnormally,user shall cut off the power immediately and send it to the designated place
for maintenance
11. 1f the safety parts for maintenance or change are not provided by us, we won t be responsible for any possible
safety quality problems.
