to the model number (ex: dcqa15 0 - 48s24r). 6. optional heatsinks available. see page 5 for ordering details. 7. m3 x 0.5 threaded - t hru inserts come standard. for ?.126 thru - hole inserts add the suffix ?th ? to the model number (ex: dcqa15 0 - 4 8s24th). models with thru - hole inserts cannot be equipped with a heatsink. 8 . base - plate grounding: emi can be reduced when you connect two screw bolts to shield plane. . caution: this power module is not internally fused. an input line fuse must always be used.
