Application

The PST range is a microprocessor based softstarter designed with the latest
technology for soft start and soft stop of motors. The PST Softstarter has several
advanced motor protection features as standard. The four button key pad and the
logic structure of the menu makes the installation, commissioning and operation
easy. It is possible to choose between 12 different languages.

The PST Softstarter can be used with or without a by-pass contactor. The larger
sizes, PSTB370 – PSTB1050, include a built-in by-pass contactor.

The PST Softstarter can be selected according to the rated motor power in
normal duty applications like pumps, compressors, elevators, escalators, short
conveyor belts and bow thrusters.

Digital key-pad

Digital display

Your business is going global. Shouldn't your motor control go global, too? The
PST display gives you information presented in plain words — in your language.
You can choose between almost a dozen languages including English, German,
Italian, Chinese, Finnish, Swedish, French, Spanish, Dutch, Russian, Turkish
and Portuguese. On the PST display, you get all the information you need to set
up, adjust and trouble-shoot. This makes the PST extremely easy to handle and
reduces the risk of misinterpretations.

At any time, you can read output current, output voltage, number of starts, total
run time and motor temperature on the display. If a fault should occur, this is also
indicated on the display. The fault messages are presented in clear text in the
selected language.
