Beckhoff Automation kl3403

The KL3403 Bus Terminal enables the measurement of all relevant electrical data of the supply network. The voltage is measured via the direct connection of L1, L2, L3 and N. The current of the three phases L1, L2 and L3 is fed via simple current transformers. All measured currents and voltages are available as root-mean-square values. In the KL3403 version, the effective power and the energy consumption for each phase are calculated. Through the relationship of the root-mean-square values of voltage U * current I and the effective power P, all other information such as the apparent power S or the phase shift angle cos φ can be derived. For each fieldbus, KL3403 provides a comprehensive network analysis and an energy management option.   The KL3403 Bus Terminal can be ordered to suit further current and voltage ranges, such as 5 A, 20 mA or 333 mV. An overview of the different versions can be found under ordering information.
