CSMshunt

Shunt-based current measurements under harsh environmental conditions

The CSMshunt device family extends the application range of CAN- and EtherCAT®-based AD MiniModules from CSM.

In conjunction with AD MiniModules, CSMshunts provide precise and safe current measurements from on-board power supply systems and electrical consumers in general. CSMshunts are directly looped into the current path that is to be measured. With additional voltage tap-offs, combined voltage and current measurements are possible.

Variants:

CSMshunt with separate measurement amplifier
CSMshunt passive for the connection to ADMM pro HS and other measurement devices with high-accuracy 50 mV inputs
CSMshunt fuse for use in a vehicle's fuse box. The safety provided by the original vehicle fuse is maintained!
CSMshunt open with separate measurement amplifier, without housing

Characteristics:

Operating temperature range: -40 °C to +125 °C
Robust housing
High accuracy over the entire temperature range

Measurement ranges	2,5 A	25 A	125 A	250 A	500 A

CSMshunt 2,5 Ampere and 25 Ampere — CSMshunt 2,5 A / 25 A with measurement amplifier

Fields of application:

Acquisition and monitoring of currents in operating and stand-by phases
Detection of "power guzzlers" in order to avoid battery problems in standard vehicles
Monitoring of the sleep and wake-up behaviors of ECUs
Measurement of discharge/charge currents of the battery (charge balance)
Monitoring and logging of the battery state, in the case of vehicle transports
Fault analysis in the service workshop, in the case of a "break down" and other vehicles with electrical / electronic problems
Long-term monitoring of currents in the vehicle continuous operation
For safe and precise measurements in HV components, the shunts of the HV BM Split Modules are suitable.
