Participation reward: 2 Wealth. Reward for correct answer: 9 Wealth. Question: Why should the voltage of the DC bus not be too high or too low?
When the voltage is too high, it can easily cause overheating or damage to relays, indicator lights, and other components that remain powered on for extended periods； When the voltage is too low, it may result in unreliable operation of circuit breakers and protective devices. The acceptable range for bus voltage is generally ±10%.
When the voltage is too high, it can easily cause overheating or damage to relays, indicator lights, and other components that remain powered on for extended periods； When the voltage is too low, it may result in unreliable operation of circuit breakers and protective devices.
Excessively high voltage can cause relays, protection modules, indicator lights, etc., that remain powered on for long periods to overheat or get damaged. .
When the DC bus voltage is too high, relays and indicator lights that remain powered on for extended periods are prone to overheating or damage; when the voltage is too low, it may result in unreliable operation of circuit breakers and protective devices. The allowable range for the DC bus voltage is generally ±10%

Answer: When the voltage is too high, it can easily cause overheating or damage to relays, indicator lights, and other components that remain powered on for extended periods； When the voltage is too low, it may result in unreliable operation of circuit breakers and protective devices. The acceptable range for bus voltage is generally plus or minus 10%
