ECPC404 Meter Assembly (Complete) Both Low and High Voltage Cutoff Protection. Grandi notizie! My problem is the type of charge I am connecting, as it commands a motor and the voltage read at the Zener goes down when the motor is turning fast, so the relay cuts-off, but as the power is not any more feeding the motor, the voltage read at the Zener goes again up enough to re-activate the relay, so the motor continues turning while the relay is very fast switching between on and off. This adjustment is done by the 10k preset , and a multimeter connected with the output terminals that goes to battery .

This inline device connects with a cigarette lighter plug and socket, and automatically shuts off power to the connected device (such as a fridge or lighting) if the voltage drops below 11.6V! 12-volt batteries supply useful energy only through a limited range — from over 14 volts (when fully charged and unrested) down to 10.5 volts in use/under load (when lights dim, pumps groan and TV pictures get small). I was thinking if put resistor in series with relay coil i could lower current so relay would barely work on 12v but when it drops to 10v voltage after resistor would be so small that relay would disconnect, Best Answer The transistor needs a load use another 4.7K resistor in place of the relay coil...Then the when the voltage across the resistor drops to zero or the voltage of the transistor with respect to GND = ground goes to the supply voltage.. You can assume the transistor is turned OFF and any 12v relay coil (has_no_positive_terminal) will release the contacts to the No_Power position.. That is the position the relay has when taken out of the shipping container as determined with an ohmeter.. BTW, how are you reducing the voltage from 12.4v to 11v ? Some controllers with user-configurable LVCs will have overly cautious defaults, like 42v for a 48v battery. ... you connect the capacitor in series with the voltmeter and a 12 volt battery (capacitor + to battery +). Perfect for use as a low voltage disconnect for loads, it can also be used … AU $12.53. I'm trying to build this circuit, but my relay is ALQ324 and has only 4 pins.
