Operating period at peak output current is 4 sec, max duty cycle<35% &< rated output power 2. At 115/230VAC, Ta = 25°C, nominal output voltage, rated output power 3. Ripple & noise is measured at 20MHz using 300mm twisted pair of load wires terminated with 0.1µF film cap & 47µF electrolytic cap 4. Constant current (CC) limit for >101% of peak output current. CC limit with auto recovery within 4 sec, unit will shutdown at >4sec 5. Output will shutdown, manual reset by mains cycle off/on or CNT on/off 6. Refer to instruction manual 7. Select /HL model for ATEX, IEC Ex and GL (Germanischer Lloyd) approvals (see optional models table) *Signal connectors are found on the topside of the unit. See product outline drawings for locations Signal Connector Pin Assignment PIN Function Detail 1 CB For parallel operation cut the link between pins 1 & 2 for droop mode current share
