AHR500B420 数据手册
AC/DC Current transducer AHR-B420 The transducer for the electronic measurement of DC & distorted AC waveform currents, with galvanic isolation between the primary circuit (power) and the secondary circuit (measurement). True r.m.s. 4-20 mA current output. IPN = 500 .. 2000 A Electrical data Primary nominal DC & AC current I PN ( At rms) 500 800 1000 1500 2000 Primary AC current max. peak value 1) I P ( A) 2000 2500 2000 2500 3000 Output currentt I OUT ( mA DC) 4-20 4-20 4-20 4-20 4-20 AHR AHR AHR AHR AHR 500 B420 800 B420 1000 B420 1500 B420 2000 B420 Type Features • DC + distorted AC waveform currents measurement • True r.m.s. output • Busbar or panel mounting • Split core type • Insulated plastic case recognized according to UL94-V0. RL VC IC ISL ÎP Load resistance Supply voltage Current consumption Output current limitation Overload capability (Ampere Turns) < 300 Ω + 20 .. 50 V DC 30 mA + IOUT < 25 mA 30000 At Advantages • High isolation between primary and secondary circuits • Eliminates insertion loss • Easy installation.
