Recitifiers
QUASAR 500 DC & DCR RECTIFIERS
QUASAR 500 is a line of switch-mode recti ers for surface treatment processes, electro-winning and water treatment. CRS recti ers use pulse width modulation (PWM) technique to control the current amplitude instead of the voltage. The result is a more accurate output current than other topologies.
