Accessories for Millenium 3 Millenium power supply With a switch mode power supply, regulated and protected against overloads and short-circuits, these new power supply units are easily integrated in switchboards and enclosures. The potentiometer can be used to set the output c voltage between 100 and 120% (24 V 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. a Broad range of supply voltage 85 V 264 V . 1 Part numbers Type Nominal output voltage Nominal power Nominal output current Code PS c 20 W 4 A 88950305 5 V (4.75 V 6.25 V) c 25 W 2.1 A 88950306 12 V (11.4 V 15 V) c 7.5 W 0.3 A 88950303 24 V (22.8 V 28.8 V) c 15 W 0.6 A 88950304 24 V (22.8 V 28.8 V) c 30 W 1.2 A 88950307 24 V (22.8 V 28.8 V) c 60 W 2.5 A 88950302 24 V (22.8 V 28.8 V) General characteristics Environmental characteristics Conformity to standards IEC/EN 60950-1 IEC/EN 61000-6-2 IEC/EN 61000-6-3 IEC/EN 61204-3 IEC/EN 55022 class B IEC/EN 60364-4-41 Certifications cULus 508 cCSAus (CSA22.2 n950-1) TUV EN 60950-1 CE Operating temperature -25 +55C Storage temperature -40 +70C Electrical characteristics Input voltage a 100 240 V single-phase Supply frequency range 50/60 Hz (+4% / -6%) or 47 53 Hz/57 63 Hz Output voltage Adjustable from 100 120% Regulation of line and load 3% Immunity from micro power cuts > 10 ms Technology Primary switch mode electronic power supplies Short-circuit protection Yes Overload protection Yes Primary protection Fuse gG 2 A or circuit breaker 2A curve D for 88950303, 88950304, 88950305, 88950306, 88950307 Fuse gG 3 A or circuit breaker 3A curve D for 88950302 Reset after overload Automatic Status indication LED at the output Mechanical characteristics Mounting On section, 35 x 7, 5 mm and 35 x 15 mm or on panel (2 x 4 mm) 2 Screw terminals connection capacity Input connection 2 x 0.14 < 2.5 mm (AWG26...AWG14) 2 Output connection 1 x 0.14 < 2.5 mm (AWG26...AWG14) To order, see page 8 1Dimensions (mm) PS 66,6 1 2 88950305 42 54 88950306 42 54 88950303 24 36 88950304 24 36 88950307 42 54 88950302 60 72 51,6 4 1 56,1 2 1 2 90 110 90 100
