During parallel operation load current is shared evenly between modules. However because of production tolerance on the output voltage
calibration and passive current sharing between modules (droop sharing) there may be a deviation of load current - up to 6% difference
module to module is possible vs. the average value. The result of this deviation may cause some modules to deliver more current than
others.
In the Table above, in the centre column (Max. power 1), is the available power when none of the paralleled modules override their
nominal current of 25A. The right column specifies condition for n modules - n * 6 kVA. In the case of Max. Power 2, some of the modules
may be operating over their nominal power. Functioning above the maximum power is however acceptable since the overcurrent
protection only activates at an output current of ~27.5A, however this is only possible when operating at a lower coolant temperature
range, so that the over-temperature protection doesn’t trip off the overloaded module.
Modules connected in a 3 phase configuration, per the diagram below are able to produce a 3 x 400 VAC output. To achieve the
240VAC, each modules L1 is connected to L2.
The slaves function at 120° and 240° out of phase from the master by setting up the addressing per the table below.
Note: Each of the address pins are digital and have an internal pull up impedances, therefore a non-connected pin will result in a logic
