Typy PSR, PSS, PSE, PST a PSTB ... Nejnovějším členem řady softstartérů ABB je optimální softstartér PSE. Tento Softstartér disponuje všemi potřebnými funkcemi pro ochranu motoru i softstartéru. Softstartéry PSE osazeny jazykově neutrálním podsvíceným displejem a 4mi tlačítky. Funkce jsou zobrazovány pomocí ikon, hodnoty a kódy zpráv pomocí 7mi segmentového displeje. V neposlední řadě jsou softstartéry PSE vybaveny zabudovaným by-pass kontaktem.
The keypad can also used
to copy parameters between different softstarters. V,
0 mA, mA
The PST(B) softstarter the most advanced softstarter the
ABB product portfolio and equipped with almost all imagi
nable features.
By-pass for energy saving
By-passing the softstarter after reaching full voltage, will save
energy and reduce the heat generaton.

. This makes the PST(B) ideal for almost every
application. offer more flexibility, all protections can be
tailored your specific needs.
Display and keypad
The PST(B) softstarter equipped with full text display show
ing all information clear text your own language.
Advanced protections
The PST(B) softstarters are equipped with almost all protec
tions imaginable for protecting the motor, the softstarter and
the application.
External keypad
As option, the PST(B) softstarter can equipped with an
external keypad for easy set-up and monitoring the unit ith
out opening the enclosure door.
Flexible analog output
The analog output terminals can connected analog
current meter show the current during operation and thereby
eliminating the need for additional current transformer.
Torque Control
The ABB torque control function developed together with
pump manufacturers ensure the best possible pump stop,
eliminating problems with water hammering and pressure surg
