Technical content

Features

♦ Highly reliable Hall Effect device ♦ Compact and light weight ♦ Fast response time ♦ Excellent linearity of the output voltage over a wide input range ♦ Excellent frequency response (> 50 kHz) ♦ Low power consumption (16 mA nominal) ♦ Capable of measuring both DC and AC, both pulsed and mixed ♦ High isolation voltage between the measuring circuit and the current-carrying conductor (AC2.5KV) ♦ Extended operating temperature range ♦ Flame-Retardant plastic case and silicone encapsulate, using UL classified materials, ensures protection against environmental contaminants and vibration over a wide temperature and humidity range

Applications

♦ UPS systems ♦ Process control devices ♦ AC and DC servo systems ♦ Motor speed controller ♦ Electrical vehicle controllers ♦ Inverter-controlled welding machines ♦ General and special purpose inverters ♦ Controller for traction equipment e.g. electric trains Specifications Parameter Symbol Unit TMQ 100A TMQ 200A TMQ 300A TMQ 400A TMQ 500A TMQ 600A TMQ 800A TMQ 1000A Nominal Input Current I fn A DC 100 200 300 400 500 600 800 1000 Linear Range I fs A DC ±300 ±600 ±900 ±1200 ±1500 ±1800 ±2400 ±3000 Nominal Output Voltage V hn V 4 V±1% at If=I fn ( RL=10kΩ) Offset Voltage V os mV Within ±15 mV @ I f=0, Ta=25°C Output Resistance R OUT Ω <10 Ω Hysteresis Error V oh mV Within ±10 mV @ I f=Ifn→0 Supply Voltage V CC/VEE V ±15V ±5% Linearity ρ % Within ±0.5% of I fn Consumption Current I CC mA ±16 mA nominal Response Time (90%Vhn) T r μsec 3 μsec max. @ d If /dt = Ifn / μsec Frequency bandwidth (-3dB) f BW Hz DC to 50kHz Thermal Drift of Output - %/°C Within ±0.05 %/°C @ I fn Thermal Drift of Zero Current Offset - mV/°C Within ±1 mV/°C @ I fn Dielectric Strength - V AC2.5KV X 60 sec Isolation Resistance @ 1000 VDC R IS M Ω >500 M Ω Operating Temperature T a °C -15°C to 80°C Storage Temperature T s °C -20°C to 85°C Mass W g 240 g
