If you use CPS-5HP model: 90 to 95% efficiency
Question / Answer
1. Only 2 phases come out from the DPS's output voltage.
3 phase voltages are output only when the motor is running. When the motor is not
running, it is normal for only single phase output to come out.
2. DPS output voltage and current are irregular.
Initially, there may be voltage and current imbalances. but when the load take
more than 50%, the voltage and current will soon balance. This phenomenon
occurs in the process of making3 phases from single phase.
3. The motor runs well at first, then suddenly the breaker was tripped.
Check the capacity of the breaker. You need to select twice the capacity of the
motor rated current. e.g.Motor 15A: Breaker 30A.
4. The power of the DPS is checked,but the motor is not running.
Check the DPS and motor connections (check whether the magnetic control lines
are connected to U and W of DPS's output).
5. Connected the DPS to the motor and running the motor, but the voltages
and current value are too high.
Check the capacity of the DPS and motor. If the DPS capacity is too large for the
motor capacity. that happens. Or. please check whether two motors are installed in
the machine. It should be used only for one DPS per one motor.
6. Is DPS available when the machine has 2-3 motors?
Originally, you should use one DPS for only one motor. However, if the start and
stop times of the motor are the same, you could use one DPS for multiple motors.
7. The DPS LED power does not come on in spite of entering power.
Please contact the head office after checking the input power.
8. The motor runs well by connecting the DPS, but suddenly it doesn't
work well.
Check the magnet switch connection, overload capacity, and breaker capacity
(twice the motor rated current) And check for the overload.
9. And check for the overload.
Check if the input voltage and power volume are normal and check the motor
