(Max 240V). The output voltage will be the SUM of twice of set volt- age of the Master. Set all the 1672, which would be connected in serial operation under serial tracking mode as described in serial tracking mode and adjusts to the same output. - Page 9 Section 6 Multiple units in parallel mode The power supply 1672 can be connected two or more units in parallel to obtain a higher current output (Max. 24A only). Set all the 1672 which will be connected in parallel operation under parallel tracking mode as described in parallel tracking mode and ad- just all units to the same output voltage.
