Advanced PWM Technology
The Chroma 61500 series AC power source is able to provide the highest possible power density by utilizing its superior PWM mode design and incorporated power factor correction functions.
AC/DC Output Capability
Chroma 61500 series AC power sources provide output DC components for simulating AC voltage with DC offset conditions. It can test unbalanced input current for rectified loads. Users can also use an optional DC noise filter to get low noise and good stability DC voltage for testing.
The Chroma 61500 series AC power source has a built in 16-bit measurement circuit and firmware utilities to measure the steady and transient responses of true RMS voltage, current, true power, VA (apparent power), VAR (reactive power), power factor, current crest factor, peak repetitive current, and inrush current. Using advanced DSP technology, it can measure up to 40 orders of current harmonics. This makes the 61500 series not only a power source, but also a powerful analyzer.

Power Line Disturbance Simulation
In addition to the steady output voltage and frequency programming, the Chroma 61500 series AC power source provides powerful functions to simulate all kinds of power line disturbance conditions. The STEP and PULSE modes offer an easy and convenient method to execute either a single step or continuous output changes. The changes can be triggered by either an internal or external event. With this capability, it is easy to simulate power line disturbances such as cycle dropouts, transient spikes, brownouts, etc.
The LIST Mode extends this function for more complex waveform generator needs. With up to 100 sequences with different start-end conditions, the 61500 can perform almost any waveform possible by AC and DC components. It also allows users to synchronize external events as well as measurement devices with output changes.
Simulation of Power Line Disturbances (PLD) can easily be programmed from the 61500 Front Panel or via Remote Interface using these Key Features:
PULSE: Create varying voltage changes using Pulsed voltage setting with Duty Cycle, and Phase angle settings.
LIST: Program up to 100 Sequences with varying Times Phase angles, Amplitudes, and waveforms.
STEP: Ramp or Step up or down by setting a Start and End Voltage and the number of steps.
Programmable Output Impedance
The Chroma 61500 AC sources allow users to program output impedance. A current feedback control circuit makes the output voltage change with the load. This feature is suitable for IEC 61000-3-3 Flicker tests or other test conditions with specific output impedance requirements. It provides users a convenient and cost effective way to implement the reference impedance.
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.
High Output Current Crest Factor & Turn On / Off Phase Angle Control
Chroma 61500 series AC power sources are capable of providing high output current crest factor (Max. 6). It delivers sufficient transient power that is required for testing most rectified input type power circuits. The programmable on/off phase angle control makes the 61500 series AC sources ideal for inrush current test.
Voltage Dips & 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, -4-13, -4-14, and -4-28 precompliance tests with an easy-use software.
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.
61500 Series AC Source Applications
Simulate AC Power Distortion
More and more electronics manufactures have expanded their business to acquire worldwide product distribution. When a problem is identified, sometimes it is necessary to check if the products are susceptible to ac line disturbances. However, precious time would be wasted on gathering and transferring test equipment, man power and other resources to do a simple onsite test. The purpose of this application is to provide a solution using Chroma Power Analyzer 6630 to measure the voltage harmonics of the ac main on site. All recorded data can be sent to the lab. According to the data, users can use synthesis function of AC source 61500 series to re-build the original distorted waveform. It can help engineers quickly point out the problem and come up with a solution.
3-Phase Mode & Series Connecting For High Voltage Output
The 61500 series AC source provides a 3-PHASE mode to let users connect 3 units for 3-phase output application. Users can set a single unit as the Master, and set others to the phase angle (120/240 degrees) as the Slaves. The Master unit will keep in Fixed mode and send a signal for synchronizing Slaves.
In the current market, more and more UUTs need to test AC line transient with high voltages greater than 300V. An external boost transformer might raise the voltage, but the serious loading effect will create a voltage waveform with large distortions. Users can connect 2 of the 61500 units in series and set the phase angle to zero (see figure) in 3-PHASE mode. Using this method, users can program a 220V/0.5sec wave superimposed on 230V wave to get 450V transient voltage with ease.
