Basic Line Modules (BLM) are compact line infeeds for two-quadrant operation, i.e. no
regenerative feedback.
Under full load, the DC-link voltage is higher than the rms value of the rated supply voltage
by a factor of 1.32, and under partial load by a factor of 1.35.
They are used in applications where energy does not have to be fed back into the line.
If regenerative conditions occur in the drive assembly, braking modules must be used
because they convert the excess energy in braking resistors into heat.
Basic Line Modules are suitable for connection to supply systems grounded at the neutral
point (TN, TT) and ungrounded supply systems (IT). The following voltages and power
ratings are available:
Line voltage
380 to 480 V 3 ph. AC
500 to 690 V 3 ph. AC
The power rating can be increased by connecting Basic Line Modules in parallel.
