System Solution to Solve Noise and Transients Beyond EN50155/EN50121-3-2
The challenge A regular customer of ours ran into problems during a locomotive retrofit. A battery chargers input circuit broke down repeatedly and the cause was identified as a combination of noise from the load and transients from pantograph bouncing. The noise and transient levels were way outside of the limits in EN50155 and EN50121-3-2, […]
Shipboard Lighting
The challenge The US Navy is moving to Solid State Lighting (SSL) with very long life LEDs. Among the reasons are to avoid drawbacks of traditional lighting, such as the relatively short life of Incandescent bulbs, the too long warm up for HSP lights, and the mercury content in fluorescent lights. For being able to […]
