Detailed Description
Main Features and Technical Parameters □ 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. □With adopting high-power MOSFEF high-frequency design, it enables noise-free operation and the consumption reduction of motor and battery. □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. □ With fully-sealed pressed aluminum shell and anodizing treatment, it enables good performance in heat sinking and improved performance in moisture resistance. □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) □under-voltage protection can extend the service life of battery. □ Over-current protection can effectively protect DC motor. □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. Technical Parameter: Applicable Voltage Range: ±20% of operating voltage Output voltage: zero to set value Ambient temperature: -20~+55℃ Maximum allowable temperature: 75℃ Speed regulation signal type: -01 is potentiometer 10K /2W, -03 is Hall handle, -04 is pedal accelerator, -02 is signal isolator(0~5V、0~10V、4~20mA) speed regulation ratio: 1:60 Ambient humidity: non-condensing
