=NOTES=
(*1) At 230VAC Nominal output voltage and maximum output current. Total output power 1248W (Ta=25˚C)
(*2) For cases where conformance to various safety specs are required, input voltage range will be 200 ~ 240VAC (50/60Hz).
(*3) Factory Programmed (Available for ×¢10% setting Range)
(*4) 100MHz B. W JEITA RC-9131 Method
(*5) When remote sense connected.
(*6) Constant Current Limit Auto recovery.
(*7) Output Shut Down Method Manual reset (Line recycle).
(*8) When resuming operation in less than 10 sec. after power failure at no load, soft start circuit will not limit the inrush current at turn - on.
Not applicable for the inrush current to Noise Filter less than 0.2 ms.
