This unit is a power conditioner (PCU) equipped with a DC / DC converter. The primary side of the DC / DC converter is equipped with a power supply switch, EMI filter, and overcurrent limiting function, and is electrically isolated from the secondary side. Four systems of + 30V, ± 15V, + 12V, and + 5V are generated as the secondary side generated voltage. The power supply switch on the primary side can be controlled by an external pulse signal. In addition, the overcurrent limit function installed on the primary side activates the current limit after the overcurrent is detected, and automatically shuts off the power supply when that state continues for a certain period of time (current limit value and cutoff time can be customized). ). By changing the installed DC / DC converter, it is possible to meet various power requirements.
