Notes from page 1
1. 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&noiseismeasuredat20MHzusing300mmtwistedpairofloadwiresterminatedwith0.1μFlmcap&47μFelectrolyticcap
4. Constant current (CC) limit for >105% 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. For -30°C startup please contact your local sales contact or relevent FAE for DIN rail
