FPA2K Thick Film Power Resistor For variable speed drivers, power supplies, control devices, robotics, motor control and other power designs. The easy mounting fixture guarantees an autocalibarted pressure to the cooking plate of approx 300 N 2000 Watt operating power Non- Inductive Design High insulation and partial discharge performance Materials in accordance with UL94-V0 RoHS Compliant Characteristics Resistance values 1R to 6K Resistance tolerance J (5%) and K (10%) Temperature coefficient 150ppm/C - others available on request, measured +25C to +85C Maximum working voltage 5kVdc - others available on request not exceeding maximum power Short time overload 2400W at 70C for 10 sec R = 0.4% max Power rating 2000W at 125C bottom case temperature resp. 60C heat sink temp Maximum continous current 120 A Electric strength voltage 7kVrms/50Hz/500VA , test time 1 min between case and terminal Single shot voltage up to 12kV normwave (1.5/50 sec) Partial discharge 4kVrms < 10pC Insulation resistance 10G min at 1000V Creepage distance >42mm min Air distance >14mm min Inductance 80nH typical, measuring frequecy 10kHz Capacity/Mass 120pF typical, measuring frequecy 10kHz Capapcity/Parallel 40pF typical, measuring frequecy 10kHz Operating temperature -55C to +150C Max torque for contacts 1.8 Nm to 2Nm Max torque for mounting 1.6Nm to 1.8 Nm M4 screws Weight ~120 g Derating Curve Derating (thermal resist.)FPA2K: 66.6 W/K (0.015K/W) Power Rating:2000 W at 125C bottom case temperture. Best results can be reached by using a thermal conduction to the heatsink R -cs<0.025K/W, which can be reached by using th thermal transfer compound with a head conductivity of 1W/mK The flatness of the cooling plate must be better than 0.05mm overall. The roughness of the surface should not exceed 6.4m ARCOL UK Limited, The information contained herein does not form part of Threemilestone Ind.
