DS820 Stand-Alone Eddy Current Power Amplifier
Latest version. For older versions, see the Literature/Information page.

DS820 Universal Pau (highlighted) is a simple and cost-effective dyno control option.
Dynamometer Control Options
Dyne Systems offers two main options for dynamometer control:
- Closed Loop
- Single-loop, utilizing the Dyn-Loc IV dynamometer controller
- Multi-loop, utilizing the Inter-Loc V dynamometer & throttle controller
- Open Loop
- About half the cost, utilizing a stand-alone Eddy Current Power Amplifier Unit.
Dyne Systems PAUs are designed to operate as stand-alone units or will interface with most available controllers. Compatible with the popular National Instruments LabVIEW™ software.
The Intelligent PAU Solution

A few examples of DS820 error and information readouts
The DS820 uses single-phase regenerative control with additional field forcing functionality, to provide ultra-fast response. Its main advances over the DS507 (see below) are LCD readout of diagnostics, faults and other information; 30 Amp capability in the rack-mounted model; and its ability to interface with all existing Dyne Systems dynamometer controllers as well as most competitors' controllers.

- NI LabVIEW™ compatible
- Stand-alone operation supported
- LCD diagnostic readouts display field current, input command, and PAU status and faults
- 0 to +10 VDC control input
- Dry contact and PCL-Level I/O
- Rack-mount units up to 30A and 277 VAC
- Wall-mount units up to 100A and 480 VAC
