Undervoltage is defined as a condition where the applied voltage drops to 90% of rated voltage, or less, for at least 1 minute. Low-voltage conditions occur when a facility asks for more power than ...

I have a universal PSU with a variety of tips and voltage that can be dialed in from 3V to 24V. The knob is not super easy to dial in though to get a precise value. However, once I set a value, the ...

This circuit provides undervoltage and overvoltage protection for dc input supply voltages (see the figure). Its undervoltage cutoff is 6 V, and its overvoltage cutoff is 11.5 V. D3 is included for ...
