Each output is rated for a continuous current, and for higher intermittent currents. The
maximum ‘on’ time for intermittent currents is enforced by the unit, and the output will be
switched off if the rating is exceeded. The display will then show the following message until
the green ‘OFF’ button is pressed to clear the trip condition:
The outputs are rated for a maximum of four times the rated continuous current for 1 minute
on / 15 minutes off. The complete curve for intermittent current ratings is shown in figure 1.3.

3PH mk2 maximum ‘on’ times
1.3.2 Output Phase Relationships
The phase relationship between the supply voltages and the output voltages are shown below.
The phase relationship between the output voltage and output current is determined by the
impedance of the load.
