While alternating current (AC) is common in homes and industries, many electrical installations utilize a dc power supply in their control boxes. This video explains the requirements for a control circuit, including operation during power failure and voltage stability. We also discuss recommended dc voltage values according to IEC standards for proper power systems and electrical safety.
