single-quadrant DC drive / motor
6 - 12 A | SR Series
The transistor switching controllers of the SR 24/48... series are short-circuit-proof one-quadrant controllers that are used for the armature supply of low voltage d.c.- drives with permanent fields.
They work as clocked controllers with a switching frequency of 16kHz.
for motors with external and permanent excitation
armature-current form factor =< 1.02 due to high clock frequency
no additional reactor required
reduced motor noise and brush wear
mounting on Euro-card with plug connector DIN 41612 or terminal connection
high regulating dynamics
degree of protection IP 00
