1.7. Protection
1.1.1 Shunt duty-cycle limit
The shunt regulator system within the Tambourine 100 power supply includes a duty cycle
limiter, which inhibits the shunt whenever the shunt "On- time" exceeds 1.5% of the
application's repetitive motion-cycle, or when a continuous braking duration of about 500msec
occurs.
1.1.2 Phase Missed Detector Circuit
Phase missed detector circuit which halts the operation of the rectifier bridge, either,
whenever any of the three Mains phases is not present, or when the three phase AC source is
significantly unbalanced. The detector attempts to revive the power supply with a cycle of
about 1 sec.
1.1.3 Levels of Temperature Management
Three levels of temperature management:
1 st Fan operation occurs at about 70°C.
2 nd Digital output – “temperature forewarn alert” occurs at around 75°C.
3 rd Bridge shutdown occurs at around 85°C.
Note :
The integrated Fan is triggered either by the Temperature-sensor located on the Heat sink, or
by the shunt duty-cycle limiter. Once triggered, the Fan will continuously rotate at interval-
lengths of about 5 minutes each, as long as one of the triggers exists.
