CI-ControlWave EFM Introduction / 1-13
The power supply operates from +4.5/+4.9 to +16Vdc or +9.6/10.3 to +16Vdc with the
nominal input supply configuration (+6V or +12V) user configured via on-board jumpers. A
supervisory circuit monitors the incoming power and the supply voltages. The isolated
supplies are shut down when the incoming voltage drops below +4.5V for a +6V system or
+9.6V, for a +12V system.
An external battery monitor is composed of an Analog to Digital Converter (ADC) and
interface circuitry.
