| AC Current transducer APR-B10 Split core transducer for the electronic measurement distorted AC waveforms current, with galvanic isolation between the primary (High power) and the secondary circuits (Electronic circuit). Switch selectable ranges and True RMS 0-5V and 0-10V switch selectable voltage output. IPN = 10 .. 400 A Preliminary Electrical data Primary Nominal Current IPN (A.t.RMS) 10,25,50 50,75,100 100,150,200 200,300,400 RL VC Vd Analogue Output Signal VOUT (V) 0-5V or 0-10V 0-5V or 0-10V 0-5V or 0-10V 0-5V or 0-10V Type Features * VFD and SCR waveforms current measurement * True RMS output * Split core type * 5V & 10V switch selectable voltage output. * DIN mounting & Panel mounting * Eliminates insertion loss * Switch selectable ranges APR 50 B10 APR 100 B10 APR 200 B10 APR 400 B10 10 k +24 5% V DC 5 kV 18 V Load resistance Supply voltage R.m.s. voltage for AC isolation test, 50/60Hz, 1 mn Limitation of voltage output Advantages * Large aperture for cable up to O18mm Accuracy-Dynamic performance data * High isolation between primary and secondary circuits < 1 % of IPN < 0.5 % of IPN < 0.5 % of IPN 1 mV/K 0.1 %/K < 1000 ms 10 .. 6000 Hz * Easy to mount X L VOE VOT TC G tr f Accuracy @ IPN, TA = 25C (without offset) Linearity (0 .. IPN) Electrical offset voltage, TA = 25C Thermal drift of VOE Thermal drift of the gain (% of reading) Response time @ 90% of IP Frequency bandwidth (-3 dB) Applications * VFD Controlled Loads: VFD output indicates how the motor and attached load are operating. * SCR Controlled Loads: Acurate measurement of phase angle fired or burst fired (time proportioned) SCRs. Current measurement gives General data TA TS m Ambient operating temperature Ambient storage temperature Mass Protection type Reliable isolation according to EN50178, EN61010 Creepage distance EMC in accordance with EN50082-2 Plastic according to UL94V0, CTI 1 -20 .. +60 C -20 .. +85 C 90 g IP20 300 V AC > 5.5 mm faster response than temperature measurement. * Switching Power Supplies and Electronic Ballasts: True RMS sensing is the most accurate way to measure power supply or ballast input power. Notes : Installation and maintenance should be done with power supply disconnected. 030708/0 LEM Components www.lem.com Dimensions AP(R)-B10 (unit : mm, 1mm = 0.0394 inch) Mechanical characteristics * General tolerance * Primary aperture * Panel mounting 1 mm 18.5 mm 2 holes 4.0 mm * Distance between holes 40.0 mm For panel mounting, replace M4 screws by new one (not supplied) with appropriate length to panels thickness.
