A range of switch-mode power supplies featuring integral microcontroller
and a choice of communications interfaces is now available from Bulgin
Power Source. Primarily aimed at battery-backed mission-critical
applications, Oracle provides a 28V main output for powering the load
together with a second output for charging an external standby battery.
In the event of a mains failure, the battery supplies power to the load
via an internal feed-forward diode. The unit can be specified with either
an RS232 port or I2C interface. These communications facilities allow
parameters such as under-voltage lockout and battery charging rate to be
programmed, or output voltage and current to remotely interrogated.
Oracle is available in 80W, 170W and 300W versions in Eurocard, chassis
mounting or DIN-rail mounting mechanical formats.
