AC power supply PCR-LE series

Setting the Output Impedance

The PCR-LE Series’ output impedance (output resistance) is approximately 0 Ω. Commercial power supplies have an impedance (resistance) of several milliohms to several ohms. You can set the PCR-LE Series’ output impedance. This enables you to simulate the same environment as that which is provided by commercial power supplies.

The impedance that is required for IEC standard tests has a prescribed inductance component, but the output impedance of the PCR-LE Series consists entirely of resistance. You can use the PCR-LESeries to perform rough harmonic current analyses. If you require accurate data, use the Line Impedance Network (LIN Series).

Press OTHERS (SHIFT+MEMORY) and then OUT IMP (F3) to set the output impedance.
