Advanced PWM Technology

The Chroma 61500/61600 series AC power sources are able to provide the highest power density possible through their advanced high speed PWM mode designs. The modularized power stage design offers outstanding performance and high reliability, and allows service personnel to identify trouble spots more efficiently and minimize downtime. With no transformer at the output stage, it not only reduces the output impedance, but also allows the 61500/61600 series to be able to program DC components for simulating AC voltage with DC offset conditions. This function allows users to simulate the test condition of unbalanced input current for rectified loads.

Single-Phase & Three-Phase Output

Chroma 61512 PanelModel 61511/61512/61611/61612 AC sources are capable of delivering single or three-phase output depending on the user’s application. Users can select these output modes easily either through the front panel or via remote control. Model 61511/61512/61611/61612 AC sources are able to provide full power output without derating even with the output configured as single phase.

Slew Rate Setting For Voltage & Frequency

Model 61511/61512/61611/61612 AC sources let users set the slew rate for voltage and frequency. The source will follow the slew rate to reach the final setting when the output voltage or frequency is changed. This function can help users verify the operation range of input power. For example, users can implement this feature to sweep the voltage gradually from 90V to 264V instead of only checking several points like 90V, 115V, 230V and 264V. Another application; in order to reduce the inrush current during motor startup or power on multiple UUT, the user can decrease the slew rate setting to achieve the objective.

Comprehensive Measurements

Chroma AC power source 61500/61600 series has a built in 16-bit measurement circuit and firmware utilities to measure the 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, the 61500 series can measure THD and up to 40 orders of current harmonics. This makes the 61500 series not only a sophisticated power source but also a powerful analyzer.

AC Source (Master-Slave) Parallel Operation

The 61511/61512/61611/61612 AC source models provide (Master-Slave) parallel operation functions, which enable users to extend the AC source power output ability by connecting AC sources in parallel. The maximum allowable number of AC source implemented for the parallel operation is 5 units. Through this feature, users can achieve a maximum power output up to 90KVA by combining 5 units of assorted AC sources of 18KVA in (Master-Slave) parallel operation mode. Users could also use the A615103 Power Stage accessory as an alternative cost effective solution for parallel operation by implementing it as slave unit. Please refer to the following figures for AC source models 61511/61512/61611/61612 in order to setup for parallel operation configurations.

To save time when arranging the input and output wiring of multiple AC sources connected in parallel operation, users can select and Implement the Chroma input/output terminal fixture (A615104/A615105) designed specifically to solve wiring issues.
