Transistor T1 is wired as a current sensor, where the resistor R1 forms the current to voltage converter. The battery voltage has to pass through R1 before reaching the load at the output and therefore the current passing through it is proportionately transformed into voltage. .
Low Battery Cut-off Threshold The low battery sensing is handled by R3 and P1 which forms a potential divider to set the base voltage of the relay driver transistor (T2). When the. .
In the above paragraphs I have explained a very simple concept of inverter overload cut-off using only transistors. However a cut off systemusing only transistors cannot be very accurate and sharp. In order to get a precision inverter. [pdf]
[FAQS about 12V inverter overvoltage protection]
Overvoltage This is caused by a high intermediate circuit DC voltage. This can arise from high inertia loads decelerating too quickly, the motor turns into a generator and. .
This is detected by an imbalance of the currents supplying the motor implying a leakage current to earth is present. This is usually caused by poor insulation resistance to earth. POSSIBLE FIXES: 1. Check insulation resistance of the motor and cabling. 2.. .
We hope you found the information in this article useful if you have a fault not listed and you need technical assistance contact our engineering team. .
This occurs when the motor is taking too much current with reference to the value in Group 99, motor data. POSSIBLE FIXES: 1. Check that motor’s load is not excessive. 2. Check acceleration time – too fast an acceleration of a high inertia load will cause too. [pdf]
