FAQ

Important Notice Regarding the Use of Our QNZ1-Q Series Energy-Saving Contactors with PWM Controllers?

With ongoing technological advancements, modern utility vehicles such as engineering machinery, electric sightseeing cars, golf carts, and patrol vehicles are increasingly adopting high-efficiency AC motors like permanent magnet synchronous motors and three-phase AC asynchronous motors. In these applications, the motor controller is typically connected to the vehicle battery via a DC contactor for power switching. While PWM (Pulse Width Modulation) modules within motor controllers contribute to energy-saving control, their potential for further efficiency improvement is limited.?

Notice to Customers

Dear Valued Customer,To ensure the normal operation and service life of the contactor, we would like to remind you: during installation, use, or testing, please ensure that the coil control wires are securely connected, strictly avoiding any loose connections.
