TM39 Datasheet
The desk-top power and energy meter TM39 may be used for representation and recording of energy, power, voltage and current in 3- and 4wire 3phase systems. With full 4-quadrant measurement capability, all powers and energies are displayed with the correct sign. Using a 3 line LCD display, both total 3-phase and per phase values (current, voltage, power and power factor) can be displayed.

The current and voltage inputs are suitable for direct measurement in 230/400V low voltage systems. To comply with safety standards the current inputs are isolated from each other and from the measurement circuit. The standard current input is 5A, 1A and 25A input are available as an option. The voltage inputs may be connected to 230/400V.
