SAFETY INSTRUCTIONS TECHNICAL CHARACTERISTICS

1. Please place the voltage regulator in a dry 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
from 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/mm2 for copper wire, 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 would cause
the equipment body produces electricity or it can't 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
electric worker shall 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 the carbon brush is worn seriously, please
change it in time, to prevent the equipment being damaged.(Please
repair the voltage regulator and change the parts in the case that the
power is cut off.)
10. If the equipment works abnormally, user shall cut off the power
immediately and send it to the designated place for maintenance, if the
safety parts for maintenance or change are not provided by authorized
personnel, we won't be responsible for any possible safety quality
problems.
1. Output Capability - when the main voltage is lower than 198V, the
output capacity of this equipment reduces accordingly; when the output
voltage is 110V, its output capacity can’t exceed 50% of rated capacity.
The relationship between output capability and input voltage can be
seen on Diagram 1 and Diagram 2.
2. Output Capacity - when the input voltage of this equipment changes
from 140V to 260V (500VA-10kVA), its overload capability is shown on
diagram 1 and diagram 2 under emergency service. (P=Output Capability;
Pc=Rated Output Capability; U=Input Voltage)
3. Synchronously Output 220V and 110V - can output 110V and 220V at
the same time.
4. Overload or Short-circuit Protection –use circuit breaker to protect
against overload or short-circuit.
5. Fan Heat Dispersion Function –the fan is controlled by the temperature
control device, when the equipment’s inner sampling temperature
reaches 50°C-55°C or above, the fan will automatically turn on to
disperse the heat. If it doesn’t reach this temperature, the fan will turn
off.

TECHNICAL CHARACTERISTICS TECHNICAL CHARACTERISTICS
6. Over-voltage Protection –if the input voltage range exceeds its standard
range, the regulator cannot keep output voltage steady. When output
voltage exceeds 246±4V, the other voltage light will turn on, the delay
light on after 5±2 s, relay of PCB board disconnect, there is no output
voltage; the over-voltage light out when the voltage back to normal, then
delay light out, the relay of PCB board pull in, the stabilizer back to
normal output voltage.
NOTE: If users find that the Over-Voltage indicator keeps turning on even
when the input voltage range is normal, please stop using the equipment and
bring it to the nearest authorized service center to have it checked.
7. Under-voltage indicator –if the input voltage range exceed its standard
range, the regulator cannot keep output voltage steady. When the
output voltage is lower than 184±4V, the under-voltage light will turn on
which shows that the regulator is in under-voltage. Users should turn off
the regulator until the input voltage range is back to normal.
Note: If users find that the under-voltage indicator keeps turning on even
when the input voltage range is normal, please stop using the equipment and
bring it to the nearest authorized service center to have it checked.
8. Long-time Delay –turn off the “Delay Time Selector” switch, the
stabilizer is under long-time delay. The normal work light on when it is
power on, the delay light out after 5± 2min, then the stabilizer starts to
output. When in the state of Over-voltage protection and Under-voltage
indication, it also takes 5 ± 2 min for the delay light out in long-time
delay mode, then the stabilizer back to normal output voltage.
Note: If the stabilizer load is followed by refrigerators, air conditioners and
other appliances, the internal air compressor cannot be continuous power
on, otherwise it will cause damage to such compressor, it is suggested to
choose long-time delay mode.
54
9. Short-time Delay –turn on the “Delay Time Selector” button switch, the
stabilizer is under short-time delay. The Normal work light on when it is
power on, the delay light out after 5±2 s, then the stabilizer starts to
output. When in the state of Over-voltage protection and Under-voltage
indication, it also takes 5 ±2 s for the delay light out in short-time delay
mode, then the stabilizer back to normal output voltage .
10. Applicable Working Conditions

OPERATION INSTRUCTION TECHNICAL SPECIFICATION
76
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 - 500VA ~5KVA is power line)
2. Turn on the power switch of the voltage regulator, the output voltage
indication of single -phase voltage regulator shall be 220V.
3. When single - phase voltage regulator outputs 220V and 110V at the
same time, the sum of load current can't exceed the rated value.
4. If the mains voltage is lower than198V (see diagram1 and diagram 2):
please use it through reducing the power referring to curve of output
capacity.
5. 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 loads, please leave enough allowance for output
capacity of voltage regulator.
6. After the voltage regulator is not used, please turn off the power switch
of consumer first, then the power switch of voltage regulator.
7. 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.
