1. Add suffix ‘-I’ to DNR120LS model number for parallel function, (120AS, 240 & 480 W models have parallel function as standard). A maximum of 3 units can be
paralleled. Total power available is 90% of the rated current of each unit.
2. For PFC version of DNR120LS, replace ‘L’ in the model number with ‘P’ e.g. DNR120LS24 becomes DNR120PS24 (Typical power factor 0.7).
3. Add suffix ‘-D’ for detachable connector option.
4. For DC standby, remove ‘-I’ and add # to the end of the model number.
