Modular power supplies PS Part number 88950302
Switch mode power supply regulated and protected against overloads and short-circuits, easy to integrate into switchboards and
enclosures
The potentiometer can be used to set the output voltage between 100 and 120 % (24 VDC versions) to compensate for any voltage
drops on the line
The LED continuously signals the presence of voltage at the output and, when flashing, triggering of the self-protection
Broad range of supply voltage
Double insulation

Derating
The ambient operating temperature of the Millenium power supplies is 55 °C. Above this, a derating is needed upto a maximum operating temperature of 70 °C. The chart below shows the power
(compared to the nominal power) that can be permanently supplied by the power supply, depending on the operating temperature.
