6kW AC-DC supply addresses new test applications

February 07, 2017 // By Nick Flaherty
Pacific Power Source is launching a lower power 6kVA member of its AFX AC-DC family that at 4U high can fit into legacy racks for applications such as avionics test.

The new 360AFX model will be launched in March and pushes available output power down to 6kVA/6kW in AC mode and 4.2kW in DC mode, compared to other AFX models that range from 9kVA to 60kVA.

All the models are based on a proprietary, all-digital, power conversion technology platform that supports a set of formerly unavailable features and capabilities used in programmable power sources. These include a direct-coupled output that allows for AC output, DC output or AC+DC combined output modes.

The 360AFX features active power corrected AC inputs with a wide input voltage range that can be deployed anywhere in the world. Voltage, waveform, current, power, phase and frequency are all programmable with 99 non-volatile setups that can be stored for quick recall as part of a test protocol to reduce remote control overhead.

Other features and capabilities include a 15Hz to 1200Hz frequency range, single 300V RMS constant power mode voltage range, programmable RMS or DC and peak current limit functions, and compatibility with the Pacific Power PPSC Manager Windows control software. These capabilities are easily controlled by the user through an intuitive front panel with a large, full-colour, LCD display or external touchscreen monitor.

The new all-digital design makes a small and light form factor possible, with 6kVA occupying no more than 4U of rack space. The 360AFX is well suited for upgrading legacy power test cabinets where additional power is required without consuming the additional space demanded by conventional AC power sources.

“This new model, offering both AC and DC power modes, expands the AFX Series into applications with lower power requirements. In particular, three-phase avionics ATE test systems that require upgrading can benefit from the compact and cost-effective 360AFX,” said Eric Lord, National Sales Manager for Pacific Power Source. “Its compact 4U rack height will fit in existing spaces when upgrading older, lower power AC or DC sources.
