1 / 6 page  8 | Softstarters Softstarters | 9 PSR – The compact range Description The PSR range is the most compact of all the ABB softstarter ranges, thereby making it possible to fit many devices into the same enclosure. The system concept with Manual Motor Starters provides a far more compact starting solution than for example a star delta starter. 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 set-up 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 softstarter design and reduce the installation time. Suitable for stopping pumps Even without using torque control, the PSR range is designed to reduce water hammering and will allow a superior stop com- pared to the direct stop resulting from a star delta starter or a DOL starter. See the special designed stop ramp with step down voltage below. System concept with manual motor starters All PSR softstarter sizes can easily be connected to the cor- responding manual motor starters from ABB, using the special designed connection kits. This will both make the mounting and the connection easier and will provide a very compact starting solution containing short circuit and thermal protection, isolation function and softstarter - 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 Product description • Wide rated operational voltage 208 – 600 V • Rated control supply voltage 24 V DC or 100 – 240 V AC • Rated operational current 3 – 105 A • Wide ambient temperature range, -25 to +60 ºC (-13 to 140 ºF) • Built-in by-pass on all sizes, saving energy and reduc- ing installation time • Potentiometer settings • Run signal relay on all devices • TOR signal relay on PSR25 … PSR105 • Optional fieldbus communication using Profibus, Modbus, Devicenet or CANopen • DIN rail mounting on PSR3 … PSR45 • Screw mounting on all sizes • Connection kits for easy connection with ABB manual motor starters • Sophisticated algorithm eliminating the DC-component and thereby providing excellent starting performance.
