CI-tronicTM Single-phase Soft Starters for commercial
compressor applications
Types TCI CH-C
The TCI CH-C single-phase soft starters
are designed for starting/stopping
of single-phase CSR motor compressors
for residential pumps, refrigeration
and A/C units.
The controller is optimised to create
softstart within 200 ms.

Start
During ramp-up the controller will gradually
increase the voltage to the motor. The soft cutin and cut-out of the start capacitor is possible
by means of SCR technology and is controlled
exactly to avoid current or voltage transients on
main supply. The soft cut-in and cut-out of the
start capacitor can also increase lifetime of it.
Capacitors
The run capacitor should be chosen according
to the motor specifications. The start capacitor
value should be chosen in relation to the winding
resistance and with respect to the start current
and/or torque, typical value is 2 – 6 times the run
capacitor. To discharge the start capacitor when
disconnected, power resistor has to be mounted
in parallel. Recommended value is 18 kΩ...270 kΩ,
500 V and 1 W minimum.
