ACS 503

ACS 503 is a three-phase AC source, specifically designed for harmonics and flicker testing. It meets the corresponding specifications as per EN/IEC 61000-3-2, EN/IEC 61000-3-3 and JIS C 61000-3-2 as well as per EN/IEC 61000-3-11 and EN/IEC 61000-3-12 for measuring DUTs having a nominal current of more than 16A per phase.
ACS 503 provides the perfect sinusoidal and stable voltage signal specified to perform fully compliant harmonics and flicker analysis despite of the mains supply frequency and steadyness of the voltage.

As per standard requirements a pure AC voltage is needed for measurements of harmonics and flicker. The output voltage of the ACS 503 is guaranteed to be sinusoidal with a very low distortion (THD) of less than 0.1% regardless of the load. Furthermore the voltage is kept stable within 0.1% independent of the load, even if the load is variable.
No matter what the condition of the mains supply might be ACS 503 fulfills the high standard for purety and stability of both the sinuoidal voltage signal and the frequency. With its power of 20,000VA it allows to measure DUTs with a nominal current of up to 16A as per EN/IEC 61000-3-2, EN/IEC 61000-3-3 and JIS C 61000-3-2. Additionally, ACS 503 allows measurements up to 32A as per EN/IEC 61000-3-11 and EN/IEC 61000-3-12 (for DUTs with a nominal current in the range of 16A up to 75A). The ACS 503 AC voltage source is electronically protected against overtemperature, overcurrent, overvoltage and undervoltage.

Used with EM TEST DPA 503 harmonics and flicker analyzers ACS 503 is fully remote controlled by dpa.control software via RS232 interface.
