2 Technical Details Electronically-controlled braking unit for three-phase asynchronous motors from.2 to 7.5 kw (with 4 V/3 AC). Features Brake for preset time and brake until standstill Automatic braking current control (effective value) Braking time and braking current can be set Safety times can be set Monitors the heat sink temperature Brake contactors switch load-free Approvals Electrical data Supply voltage AC: , , , , V Tolerance 9... % Power consumption Max. 4 VA Switching capability to EN , /9 AC: 25 V/ A/25 VA DC: 24 V/ A/2 W Contact material AgCdO Contact fuse protection 6 A quick or 4 A slow Fuse protection of main current circuit 25 A/68 A 2 s for 5 A version 5 A/7 A 2 s for 3 A version Features 5 A (to 45 V AC with internal braking contactor) 3 A Setting ranges of braking current A eff or A eff Safety times, adjustable t V = 24 ms ( 2 ms to 5. s ) t V2, t V3, t V4 = 4 ms ( ms to 5. s) Braking time (monitoring time) to 945 s, can also be set to infinity Remote control connection Potentiometer 47 kw for ext. braking current set value Potentiometer 47 kw for ext. braking time set value Manually controlled braking process Via start contact at terminals 6/7 Pulse duty cycle 5 A version: :7 with t Brake = s 3 A version: : with t Brake = s Environmental data Ambient temperature C Storage temperature C Mechanical data Max. cross-section of the ext. conductor 2 x.5 mm 2 or x 2.5 mm 2 Single-core or multi-core with crimp connector Dimensions (H x W x D) 87 x 9 x 45 mm Weight 9 g Description Control logic with microcontroller power semiconductor Integrated brake contactor in units up to 5 A/45 V AC Setting via keypad LCD display Remote control option for - Braking time - - Manually controlled braking Non-volatile parameter memory Option for evaluating motor temperature sensor (PTC resistor) 9 mm housing, DIN-rail mounting Pulse Duty Cycle The following are the decisive factors in selecting the PKB-M Nominal current of motor I N (I N x 2 = Max. braking current I B ) and Pulse duty cycle T V t B T V = (T B 25 C/ % I B ) t P The 3 A unit can be used to brake large motors to standstill. The ratio of the nominal motor current and braking current can no longer be set at : 2. The braking effect is therefore reduced. When setting braking time (t B ), ensure that the pulse duty cycle set for the unit is not exceeded.
