　　CA PFS - Measuring Inrush Current for Power Failure Simulators

　　The inrush current of a power failure simulator according to EN/IEC 61000-4-11 can be verified with the CA PFS circuit box. Annex A.3 of the EN/IEC 61000-4-11 standard makes specific requirements for its circuit. The built-in current provides a 10mV/A voltage signal at the corresponding BNC output terminal connected to the oscilloscope, and the inrush current is measured through the selected 1M ohm input resistance.
main feature:

　　Combined Calibration Kit

　　Conforms to EN/IEC 61000-4-11 standard

　　Built-in 10mV/A current probe

　　Built-in 3.3kohm resistor for energy storage capacitor discharge

　　The monitoring output is used to measure the residual capacitor voltage (voltage division ratio 100:1)

Standards compliant:

　　IN 61000-4-11

　　IN 61000-4-34

　　IEC 61000-4-11

　　IEC 61000-4-34

Application overview:

　　Based on the power fault generator specified in EN/IEC61000-4-11, the generator needs to withstand the surge current higher than 500A@220-240VAC and 1000A@250-600VAC.

　　EN/IEC 61000-4-34 stipulates the minimum surge current and rated equipment current of 500 A and above or even more than 1000A.

　　Power supplies are usually not capable of delivering such high inrush currents. The true current supply from the mains is limited by the supply system impedance and is expected to be around 100 A to 200 A. The following guidelines are recommended to be followed in order to properly verify the surge current generator for a mains fault:

　　A peak current capacitor of about 20 uF or more is installed in parallel with the mains. This capacitor will provide the peak inrush current generator into the CA PFS through a power failure. Due to the high inrush current and mains fuse test duration is limited to a few milliseconds. The maximum duration td depends on the current capacity of the overcurrent protective device installed in the mains. When testing, the power failure generator must be set to dU mode with only one PFS input (PF1 or PF2) connected to the power supply. Measure the inrush current with a digital memory connected to the BNC output.

　　Oscilloscope input impedance = 1 M ohm

　　500A=5V peak signal

　　The built-in storage capacitor (1700 uF capacitor) only needs to be discharged to a few volts before the next inrush current measurement. This residual voltage can be output with a voltmeter at the capacitor voltage (divider ratio 100:1).
