Programmable AC/DC Power Source ES series

Model Model Name Remarks ES4152 Reference Impedance Network Single phase, 20 A rms ES4153 Reference Impedance Network Three-/Single-phase, 20 A rms (for each phase) As-517A/ As-537 Voltage Dips Simulator Requires ES0406D

Reference Impedance Network

	For IEC 61000-3-3/JIS C 61000-3-2 Measuring Harmonic Current and Flicker This is a circuit network of resistance and inductance to make the output impedance of AC power source come near the impedance of actual commercial line. Use this in combination with Programmable AC Power Source ES series in harmonic current measurement or flicker test.
	The impedance value is guaranteed at the value given by the combination of ES series and this unit. The errors caused by impedance switching relays or current detecting resistor are corrected with feedback. Equipped with voltage/current monitoring terminal for connecting analyzer

Model Description ES4152 Single phase 2 wires ES4153 Single phase 2 wires /3 wires, Three phase 3 wires/ 4 wires

Voltage Dips Simulator

For IEC 61000-4-11 (2004) Voltage Dips, Short interruptions, and Voltage Variations
	When combining ES series with As-517A / As-537 Voltage Dips Simulator, ES0406D Immunity Software can be used to test phase currents up to 16 A according to the IEC 61000-4-11 (2004) standard single-phase or three-phase. As-517A / As-537 Voltage Dips Simulator is using high-speed semiconductor switches to achieve rapid voltage switching.
	For single-phase test, one As-517A, ES0406D software , and ES series AC power source system are required. For three-phase tests (phase voltage and line-to-line voltage tests), two As-517A, one As-537, ES0406D software, and ES series AC power source system are required.

Model Description As-517A Voltage Dips Simulator As-537 Voltage Dips Simulator for three-phase tests (phase voltage and line-to-line voltage tests)

*For IEC 61000-4-34 (for equipment with input current more than 16 A per phase), custom voltage dip simulators are required. Please contact us for further details.
