Rated values
The table below shows the rated input and output currents, as well as the specifications for sizing the cables (cross-
section, maximum length) and the fuses. The values refer to an operating temperature of 60°C, recommend air flow,
and a switching frequency of 8 kHz, unless otherwise specified.

Note:
(1)
Rated input current is referred to minimum and maximum input voltage.
(2)
Referred to following conditions:
• 230Vac/115Vac input voltage;
• 230Vac output voltage;
• rated output current;
• the power output of DCbus is included.
PS2**122***** models are sized to delivery up to 750 W to DCbus output.
PS2**061***** models are sized to delivery up to 440 W to DCbus output.

Note:
Air flow is referred to the heatsink section perpendicular to fins. A duct for conveying air flow is suggested.
If the air flow to heat sink is reduced, the product places itself under protection.
