The power supply voltage can work normally between the specified ranges. The driver is
prefer ably powered by naun regulated DC power supply,or a transformer buck+bridge rectifier
+ capacitor filter. Note, however, that the peak voltage ripple after rectification should
not exceed its specified maximum voltage. It is recommended that the user supply power with
a DC voltage lower than the maximum voltage to prevent the grid from fluctuating beyond the
operating range of the driver voltage.
If using a regulated switching power supply, be aware that the output current range of the
switching power supply must be set to maximum.
Please note:
When wiring,pay attention to the positive and negative poles of the power supply,do not
reverse connection;
It is better to use an unstable power supply;
The output capacity of the power supply current should be greater than 60% of the set current
of the driver when an unstable power supply is used;
When a regulated switching power supply is adopted, the output current of the power supply
shall be greater than or equal to the working current of the driver;
To reduce costs, two or three drives can share a power supply, but the power supply should
be large enough.
