1. Operational Status Register:
The operational status register records signals that are part of the power supply’s normal operation. In
addition to the normal operation data, the register holds an alarm bit which indicates that one of the
alarm (fault) register bitsis set. The register is automatically updated and reading it does not change it’s
content. Clearing the register is done by DCL command. See table 5-5 for Operational Status Register
content.
Note:
*1 In case ofAC fail, the alarm status register ‘AC fail’bit will be set but will not set the alarm bit.
