9.6 Very High Power
This section gives access to:
Naming of output
Set inrush current threshold
Set time interval for inrush current
Set the normal fused threshold
Set the number of retries once a fault is detected before switching off
Set the time interval for fault resetting
2 very high power outputs are available, supplying a maximum continuous current of 26..100 A
each channel.
Please observe that our default maximum current level for each channel is set in accordance with
Deutsch’s current limit for the size AWG16 contacts in the Autosport 20-16 connector.
Current draw can be measured on all outputs.
The driver stages can deliver significantly more current, but it is important to avoid overloading the
wiring and contacts in the connector.
Once an output is turned on, the current draw depends on the attached load.
- If this load is a resistive load, there will hardly be any inrush current.
- If the output drives a motor or a lamp, for example, there can be a substantial inrush for a
certain amount of time. The current draw will quickly decrease and reach a steady state
level.
Outputs are protected by three current
thresholds and three timers:
- OCH is the high current threshold of 300
A.
- OCL is the user defined continuous
current threshold, selectable as 2 x30
(60A) to 2 x 50 A (100A).
- OCS is the software selected current
threshold.
Switching an output ON, an inrush current
up to 300 A is allowed for a 20 usec time
interval.
After these 20 usec the current level must be
below OCH which is maximum 80..100 A.
