Data sheet
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.
Features
y Control voltage 208 – 240 V AC
y SCR controlled soft cut-in and cut-out
of the start capacitor
y LED status indication
y Automatic adaptation to 50/60 Hz
y Easy and quick installation
y Built in varistor protection
y IP20 protection
y Compact modular design
y DIN rail mountable
y Ramp-up time < 200 ms (factory set-up)
y EN 60947-4-2
