KONE Elevator Parts Original Power Rectifier Board Model S6121M3 with One Year Warranty for Emergency Power Supply

KONE Elevator Parts  Power Board Power Rectifier Board Original Parts S6121M3

The Kone S6121M3, an EBD (Electrical Device) driver power supply printed circuit board, primarily operates on power conversion and control to ensure emergency power supply. The following is a detailed description:

Normal Power Transmission and Management: During normal operation, the S6121M3 circuit board processes incoming power (such as mains electricity) through its internal circuitry. The copper conductors on the circuit board act like a transportation network, transmitting current to various electronic components, such as resistors, capacitors, and chips, providing the necessary power for proper operation, thereby ensuring the proper functioning of the elevator's control system, drive system, and other components.

Emergency Power Switching and Drive: When the normal power supply fails, the S6121M3 circuit board detects the abnormal power supply fluctuations. It then rapidly activates the connection and conversion mechanism for a backup power source (such as a battery). Through specialized circuitry, this backup power source's energy is converted to a voltage and current suitable for the elevator's drive system. For example, a switching power supply circuit may be used to convert the direct current from the battery into alternating current of the specific voltage and frequency required by the elevator drive motor to drive the elevator to a pre-set floor and ensure the safe evacuation of passengers.

Safety protection and signal feedback: Various protection circuits and sensors are integrated into the circuit board. These circuits can automatically cut off power or take other protective measures in the event of abnormal conditions such as overcurrent, overvoltage, or short circuits, preventing damage to the circuit board and elevator equipment. Sensors can also monitor the circuit board's operating status and power supply in real time, feeding back relevant signals to the elevator control system so that the control system can promptly understand the power supply status and make appropriate decisions.
