Harmonics, Interharmonics Synthesis

Traditional type of AC source only allows users to composite integer orders of harmonic components into a periodic harmonics distortion waveform. IEC
61000-4-13 standard requires not only the harmonics waveform,
but also interharmonics simulation. This means the fundamental
frequency will incorporate with components frequencies between
harmonics frequencies. Chroma AC power source 61500 series
uses advanced DSP technology to synthesis the harmonics and
interharmonics waveforms. Therefore, it is capable of generating
a non-periodic harmonic distorted waveform to perform IEC
61000-4-13 compliance test with an easy-use software.

Arbitrary Power Amplifier

The external voltage programming input of Chroma AC power source 61500 series allows users to feed any AC+DC waveform from an arbitrary signal
generator. And amplify the signal accordingly. It can be used to simulate the real mains supply waveforms observed in the field.

Chroma 61500 AC Power Source

High Output Current Crest Factor and Turn On / Off Phase Angle Control

Chroma AC power source 61500 series is capable of providing high output current crest factor (Max. 6). It delivers sufficient transient power required for
testing most of the rectified input type power circuits. The programmable turn on (off) phase angle control makes the 61500 series AC source ideal for inrush
current test.

Voltage Dips and Variation Simulation

IEC 61000-4-11 voltage dips, short interruption and variation standard have become mandatory in EMC directives for the CE mark. Chroma AC power source
61500 series is capable of simulating all sorts of voltage dips, interruptions and variation waveforms for IEC 61000-4-11 pre-compliance tests with an easy-
use software.
