PROGRAMMABLE AC POWER SOURCE

MODEL 61500 SERIES

Chrom a AC power source 61500 series sets up

the new standard for high performance AC power

source. It equips with all powerful features such

as powe r line distu rban ce (PLD) si mula tio n,

programmable output impedance, comprehensive

mea surement functions, wave-sha pe synthesi s

and regulation test software. These features make

th e 61500 ser ies ideal for comm ercia l, po we r

electronics, avionics, military and regulation test

Line up from 500VA to 4000VA with one phase

output, the 61500 series give users the maximum

assurance, to production test.

Using the state-of-the art PWM technology, the

61500 series is capable of delivering up to 6 times

of peak current compared to its maximum rated

current that makes it ideal for inrush current test.

The AC+DC modes extend the applications not

only pure AC volt age but als o DC component

for testing DC offset in laboratory. Applying the

advanced DS P techn ology, the 61500 se ries is

able to provide precision and transient voltage

waveform as well as measurements such as RMS

voltage, RMS current, true power, power factor,

current crest factor and up to 40 orders of current

harmonic components.

The 61500 series allows users to compose different

harmonic components to synthesize their own

harmonic distorted wave-shapes. To simulate the

natural waveform, the 61500 series also provides

an external analog input to amplify the analog

signal from arbi trar y signal gene rator. T hu s, it

is capable of simu lating the un ique wavefor m

Advanced PWM Technology

Chroma AC power source 61500 series is able to provide the highest

power density by its superior PWM mode design and the incorporated

power factor correction function.

AC/ DC output Capability

Chroma AC power source 61500 series provide output DC component for simulating AC voltage with DC offset condition. It can test the unbalance input

current for rectified load. Users also can use an optional DC noise filter to get low noise and good stability DC voltage for testing.

Comprehensive Measurements

Chroma AC power source 61500 series has built in a 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 the advanced DSP technology, it can measure up to 40 orders of current harmonics. It makes 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, Chroma AC power source 61500 series 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 a single step or continuous output

changes. The changes may be triggered by an internal or external event. With this capability, it is easy to simulate power line disturbances such as cycle

dropout, transient spike, brown out and etc.

The LIST Mode extends this function for more complex waveform generator needs. Up to 100 sequences with different start-end conditions, that can

perform almost any waveform by AC and DC components. It also allows users to synchronize external events as well as measurement devices with output

changes

Programmable Output Impedance

Chroma AC source 61500 series allows users to program output impedance. A current feedback control circuit makes the output voltage changed with

the load. This feature is suitable for IEC 61000-3-3 Flicker tests or other test condition with particular output impedance requirement. It provides users a

convenient and cost effective way to implement the reference impedance.
