JLM 1U Meter

Post by chrisp »

For those with spanking new JLM meters, for cutout see http://www.nissei.com.cn/productVM-22.html

Joe, do you recommend any particular resistor in series with the led/lamp? I'm running just +48V and 0V at the moment and don't want to introduce a new power level if I can avoid it. I'd normally be thinking something between 2K and 5K.

Thanks

The JLM meter has a white LED which needs to be run about 5mA to 10mA. So on 48v a 4k7 to 10k resistor will work.

About 3mm as I recall.
