Psr Compact Starter

PSR Compact Starter Type PSR, covers motor currents form 3 to 45 A. It is the latest addition to the soft starter family and has an attractive, compact design. Further, the system concept includes MMS and the soft starters are available for remote control connection using the FieldBusPlug as an accessory. All sizes include a Run signal relay, while from sizes 25 A the PSR Soft starters are also provided with an output signal for TOR (Top Of Ramp), i.e. full voltage). With standard performance the PSR Softstarters handle ten starts per hours. When auxiliary cooling fan is added, the starting capacity is increased to 20 starts per hour. Current ratings 3.9 - 45 A (1.5 - 22 kW), at 400 VMotor voltage 208 - 600 VSupply voltage 24 V DC or 100 - 240 V ACEasy to install and adjustDIN rail or screw mountingIntegrated by-pass contacts With their compact design, the PSR Softstarters are ideal for installation in places where space in limited and where there is a demand for easy installation.Technical Data Rated insulation voltage, Ui 600 V Rated operational voltage, Ue 200...600 V + 10%/-15%, 50/60 Hz +- 5% Rated supply voltage Us 100...240 V AC or 24 V DC + 10%/-15%, 50/60 Hz +- 5% Power consumption, at 100-240 V AC at 24 V DC PSR3 12 VA 5 W PSR6 12 VA 5W PSR9 12 Va 5 W PSR12 12 VA 5 W PSR16 12 VA 5 W PSR25 12 VA 5 W PSR30 12 VA 5 W PSR37 10 VA 5 W PSR45 10 VA 5 W Rated operational current, lr PSR3 3.9 A PSR6 6.8 A PSR9 9 A PSR12 12 A PSR16 16 A PSR25 25 A PSR30 30 A PSR37 37 A PSR45 45 A Starting capacity at lr 4 x lr for 6 sec.
