This family of 2-Phase Motor
Reversing Controller is de-
signed to control the directon
of 3-phase motors rated up to
5.5 kW. The built-in interlock-
ing circuitry prevents the relay
from switching both direc-
tions simultaneously and pro-
duce a short-circuit between
the 2 phases of the output. A
dual colour LED indicates di-
rection "forward" when green
and direction "reverse" when
red. The output is protected
from excessive voltage fluctu-
ations (transients) by built-in
varistors. Furthermore, opti-
mum reliability is achieved by
soldering the output thyristor
chips directly on to the
ceramic substrate (Direct
Copper Bonding).
The housing is designed to
incorporate a temperature
limit switch. It is recommend-
ed to install an appropriate
semiconductor fuse in series
with the relay.

* It is suggested that the input lines be installed together (such as a 3 core cable)
to enhance susceptibility.
** Surge immunity level with an external transient voltage suppressor (47V) meets
PC2 @ 1 kV between line to line and 2kV between line to ground.
Note: EMC tests were performed with representative motor loads of 1.1kW and
4.0kW. The above is just an indication of the EMC performance. The performance
of the controller would have to be evaluated with the device connected and fitted as
part of the complete system in the end application.
