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.
