DC Thyristor Controllers : SR [6 - 12A]
Function :
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.
Product characteristics :
-
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
-
short-circuit-proof
-
degree of protection IP 00
