3.10.5 External charging resistor
The following external charging resistors are available from Control
Techniques and can be used with a regen system consisting of multiple
regen, multiple motoring or single regen, multiple motoring drives. For
correct sizing of the charging resistor required, refer to section
11.2 Resistor sizing for multiple drive systems on page 204. Also, see
section 10.4.2 Softstart resistor - type TG series on page 197 for further
technical data and thermal protection information on the following
resistors.
