These diode stack are used for laser beauty machines . They mainly has 50W/bar and 100W/bar options, 50W/bar, with current 50A; while 100W/bar with 100A . Voltage: 1.8V/bar.
For 10 bars of 50W/bar, it is 5010=500W in total ; 10 bar of 100W/bar, it is 10100W=1000W. They are the main electrical features.
