Eddy Current Dynamometer
EC Series
-
Specifically designed for small displacement diesel engines, the Eddy Current (EC-Series) engine dynamometer features in-line eddy current absorption units in a robust, compact frame. The air-cooled eddy current absorbers eliminate the need for an expensive water recirculation system and most engines being tested can be cooled with a standard closed-circuit radiator system. This compact air-cooled design results in a minimal environmental impact and the ability to be easily relocated with no need for a permanent installation. When combined with PowerNet LT, our fully automated dynamometer control system, all of your testing needs can be performed at the touch of a button.

Current Mirrors
-
Analog Devices current mirrors are precision, high dynamic range, wide variable supply parts used for optical power monitoring, voltage biasing with current monitoring, and voltage-to-current conversion. Our current mirrors can monitor current down to as little as 3 nA and as much as 3 mA, with a linearity of 1% or better. The current dynamic range is 120 dB or 6 decades of current range, while the overcurrent protection feature in our devices forces the input pin to ground to avoid part damage. Over temperature (–40°C to +85°C) and process, the dynamic range only suffers 10 dB at the lower end of the range.
