Universal Eddy Current Power Amplifier Unit (PAU) Introduced by Dyne Systems

Share Article

For eddy current dynamometer users, the DS820 is a third generation, intelligent Power Amplifier Unit that will prove indispensible in its flexibility. Whether upgrading existing test cells or for implementing new test installations, the DS820 interfaces with all of Dyne Systems' existing controllers, as well as any PC/PLC based dyno controller running third party software, such as National Instruments LabVIEW.

For dynamometer users, Dyne Systems introduces the DS820, a third generation intelligent, universal eddy current Power Amplifier Unit (PAU). Its totally new digital design offers a greater flexibility for upgrading existing dyno test cells, or for implementing new test installations. Applications range from simple manual, stand-alone control to fully integrated, closed loop implementation. The DS820 interfaces with all of Dyne Systems' existing dynamometer controllers, as well as other industrial PC/PLC based controllers running third party software.

The DS820 provides a unique set of features. The front panel diagnostic LCD display eliminates guesswork by displaying real-time field current, input command, status, and fault messages. Error messages can also be reported via PLC level I/O to external controls. An analog 0 to 10 VDC input enables the unit to be used as a standalone, open loop eddy current power amplifier for simpler applications; or it can be integrated into existing test cells with fully integrated closed-loop control units by OEMs, independent testing houses and universities.

Setup is simple and straightforward, and modular construction of the PAU allows the DS820 to be interfaced with a variety of different dynamometer control components. With significant increased current capabilities, this unit is now available in a space-saving and reduced wiring rack-mount version. Wall mount units include a standard 15 amp, 30 amp, 50 amp, and 100 amp ratings at up to 480 VAC. Higher nonstandard amp ratings can easily be custom engineered.

For customers who prefer to get leading-edge performance and test cell system integration from a single provider, Dyne Systems' new DS820 fully integrates into a sophisticated family of dynamometer and control equipment that can be configured to meet high level, automated test program execution. Dyne Systems solutions include the multi-loop Inter-Loc V, Operator Control Station, single-loop dynamometer and throttle controls, Companion III Data Acquisition systems, Cell Interface Assistant hardware, and Cell Assistant automated test program software.
