The KL3448 is a three-phase power measurement terminal from the Beckhoff Bus Terminal series (KL series) for the traditional K-Bus I/O system, designed for direct measurement of electrical power in three-phase AC systems. Based on its designation, it combines the extended KL34xx power measurement feature set with 8 current input channels (for multi-circuit or multi-path current measurement). The exact channel configuration and functional scope must be confirmed against the current Beckhoff datasheet.

The KL3444 is a three-phase power measurement terminal from the Beckhoff Bus Terminal series (KL series) for the traditional K-Bus I/O system, designed for direct measurement of electrical power in three-phase AC systems. It measures voltage and current on all three phases and calculates RMS values, active/reactive/apparent power, power factor, frequency, and energy, delivering the results to the controller. It is an extended variant within the KL34xx power measurement family; the exact feature differences versus the KL3403, KL3404, and KL3408 should be confirmed in the current Beckhoff datasheet.

The KL3408 is a three-phase power measurement terminal from the Beckhoff Bus Terminal series (KL series) for the traditional K-Bus I/O system, designed for direct measurement of electrical power in three-phase AC systems. Based on its designation, it extends the KL340x family with 8 current input channels (for example, for measuring multiple circuits or phases with additional current channels). The exact channel configuration and functional scope must be confirmed against the current Beckhoff datasheet.

The KL3404 is a three-phase power measurement terminal from the Beckhoff Bus Terminal series (KL series) for the traditional K-Bus I/O system, designed for direct measurement of electrical power in three-phase AC systems.
