SPECIFICATIONS

Inventory of new large-flow 12V brushless impeller water pump, the water pump should be used for automobile heat dissipation circulation, large-scale pump workmanship quality is very good, built-in drive circuit, measured water flow is very large, the measured power is about 250W, the working current is about 18A, the current size is specific to the voltage level, the high voltage current will be smaller, the car water pump is resistant to high temperature, generally 100 degrees of water circulation is no problem, the current flow is not tested, the flow rate is too large, there is no way to actually test.
See the introduction definition of the water pump power interface, and send a 15CM long wiring plug terminal wire.
When the pump is powered on, be sure to pay attention to the positive and negative electrodes. The measured maximum voltage can work from 8-20V. Connect the positive and negative electrodes of the power supply, and then the pwm signal line will start when connected to the positive electrode water pump. It will start after about 2 seconds. If the speed control signal voltage is required, a 100hz PWM signal of 12V is required. The impeller pump cannot self-priming. It needs to fill the water inlet to the inside of the impeller to prevent backwater. You can add a one-way check valve to the water outlet to prevent backwater.
The stock of the water pump is new, and the basic quality is very good. Some may be slightly oxidized when the bottom of the back cover touches the cardboard. The functions are all tested and shipped.
