Current Sensor

Reliable PV Current Measurement Hall Sensor for Solar Applications

Principle CHK_LB5S2 series Hall Effect Open Loop Current Sensor is a current measurement device which develops on base of the hall effect principle, wherein a Hall-effect device (HED) produces an output voltage linearly related to the amplitude and phase of a magnetic field applied to it. * Open- loop * Supply voltage: DC +5.0V * Capable measurement of currents: DC, AC,pulse with galvanic isolation between primary circuit and secondary circuit. Applications * Inverter applications * AC/DC variable-speed drive * Uninterruptible Power Supplies (UPS) * Switched Mode Power Supplies (SMPS) * Frequency drive control home appliances Specification Electrical data:(Ta=25ºC,Vc=+5.0VDC,RL=2Kilohm) Parmeter Ref CHK50LB5S2 CHK100LB5S2 CHK200LB5S2 CHK300LB5S2 Rated input Ipn(A) 50 100 200 300 Measuring range Ip(A) 0~±50 0~±100 0~±200 0~±300 Output voltage Vo(V) 2.500±2.000*(IP/IPN) Output voltage Vo(V) @IP=0,T=25°C 2.500 Supply voltage VC(V) +5.0 ±5% Accuracy XG(%) @IPN,T=25°C < ±1.0 Offset voltage VOE(mV) @IP=0,T=25°C < ±30 Temperature variation of VOE VOT(mV/°C) @IP=0,-40 ~ +85°C < ±1.0 Linearity error εr(%FS) < 1.0 Di/dt accurately followed(A/µs) > 100 Response time tra(µs) @90% of IPN <3.0 Power consumption IC(mA) 15 Bandwidth Bw(KHZ) @-3dB, IPN DC-20 Insulation voltage Vd(KV) @50/60Hz, 1min,AC 2.5 General data: Parameter Value Operating temperature TA(°C) -40 ~ +85 Storage temperature TS(°C ) -55~ +125 Mass M(g ) 25 Plastic material PBT G30/G15, UL94- V0; Standards IEC60950-1:2001 EN50178:1998 SJ20790-2000 Dimensions(mm): Connection General tolerance General tolerance:< ±0.5mm Primary through-hole:D16.0±0.15 Connection of secondary : 5pin 0.635*0.635 Company Profile Packaging & Shipping Package All our sensors will be well packed with bubble & carton.
