Application example for DC

Risk of electric shock and damage of device! Bring the bus terminal system into a safe, powered down state before starting installation, disassembly or wiring of the bus terminals! |
 | Switch off the DC filter for DC measurements Switch off the DC filters for the KL3403 (using the configuration software KS2000 or the register communication (register R32.4)) for measuring direct voltage and DC. |
Power measurement at a fieldbus station
The example illustrates power measurement at three circuits of the fieldbus station. The terminal measures the:
- Power consumption of the Bus Coupler and K-Bus supply
- Power consumption of the power contacts
- Power consumption of the AS-i power supply terminal (KL9528)
Notice | |
Note rated current! In the example, the special type KL3403-0010 is used with an extended current measuring range (5 A max.). The standard KL3403 type is not suitable for this application example because the current measuring range is too small (1A)! |
