5 / 7 page 8 Softstarters | 1SFC132005C0201, rev. M 1SFC132005C0201, rev. M | Softstarters 9 PSR – The compact range Description The PSR range is the most compact of all ABB’s softstarter ranges. The compact PSR range makes it possible to fit many devices into the same enclosure. A PSR together with a MMS (manual motor starter) makes up a far more compact starting solution than a Star-Delta starter, for instance. Flexible mounting PSR softstarters from 3 to 45 A are possible to mount on a DIN-rail, ensuring quick and easy mounting. Naturally, all sizes can be screw mounted. Few settings The setup of the PSR is easily done and confirmed using the three clearly marked potentiometers on the front. Built-in by-pass for energy saving The built-in by-pass on all sizes does not only save energy; it will also ensure the most compact ABB’s softstarter design and reduce the installation time. Thanks to the reduced heat generation, the softstarter can be mounted inside high IP class enclosures. Suitable for stopping pumps Even without using torque control, the PSR range is designed to reduce water hammering. Compared to the direct stops of a Star-Delta starter or a DOL starter the PSR is superior. See the stop ramp with step-down voltage below. System concept with manual motor starters All PSR softstarter sizes can easily be connected to the corresponding manual motor starters from ABB by using the special designed connection kits. This makes both the mounting and the connection easier and will provide a very compact starting solution containing short circuit and thermal protection, isolation function and soft starter - everything that you need. Start = 1 ... 20 sec Stop = 0 ... 20 sec - including the step down voltage. Step down = 2% reduction for each second increased stop ramp Stop ramp 10 sec -> step down 80% (20% reduction) U ini = 40 ... 70% results in end voltage = 30 ... 60% 3 2 1 3 1 2 Uini Uend Start Stop Step down 3 1 2 2 3 PSR – The compact range Overview PSR3 ...
