Main Features and Technical Parameters
1.Monitoring on operating voltage:
By measuring the effective value of battery voltage, it enables the alarming indication when battery voltage
is lower than the 20% of rated voltage, which prompts the operator to timely charge the battery.
In this way, it can effectively protect battery from undercharge damage and extend its service life.
2.With adopting high-power MOSFEF high-frequency design, it enables noise-free operation and the consumption reduction of motor and battery.
3.With adopting pure copper and tinning for connection wire of heavy current and self-locking plug-in on control terminal, the connection becomes more reliable.
4.With fully-sealed pressed aluminum shell and anodizing treatment,
it enables good performance in heat sinking and improved performance in moisture resistance.
5.With over-temperature protection (75) circuit,
it enables the controller to effectively protect itself when overloading
(Note: output stops on overheating and it will automatically restore in 10 minutes)
6.Under-voltage protection can extend the service life of battery.
7.Over-current protection can effectively protect DC motor.
8.With over-voltage protection,
it can effectively protect the DC motor and controller from damaging due to over-voltage when voltage is higher than the 20% of rated voltage.
