Tips: How do I protect my circuits from overvoltage when using a variable DC power supply?

To protect circuits from overvoltage when using a variable DC power supply, employ a voltage regulator or a crowbar circuit. A voltage regulator maintains a stable output voltage, preventing it from exceeding a predetermined level. Adjustable voltage regulators like LM317 allow you to set the desired output. Alternatively, a crowbar circuit involves a zener diode and a thyristor. The zener diode monitors voltage; when it exceeds a threshold, it triggers the thyristor to short the circuit, blowing a fuse or triggering a circuit breaker. Properly sized fuses and transient voltage suppressors can offer additional protection. Regularly check and calibrate your equipment, and consider using an overvoltage protection module. These measures safeguard your circuits against potential damage due to fluctuations in the variable DC power supply.
