Quasi-Wide-Range Input: With the switch in the 230V position the power-supply unit operates at low and moderate loads at any input voltage
between 95 and 264 V AC (see ’Output’ at the right side).
Note: At DC input, always leave the switch in the 230V position
Input current< 1.3 A (switch in 115V position)< 0.7 A (switch in 230V position)

To be fused with a 10A, B-type 'circuit-breaker' switch based on theusual thermomagn. overload sensing principle (used anyway to fuse
the input lines). In addition, the unit contains an internal fuse (not accessible)

Design advantages:• Input and output pluggable by means of Combicon® plug connector.
• Ensure strain relief of the plug connectors
when installing the unit.
• Input and output are strictly apart from each other and so cannot bemixed up (input below, output above).

Output characteristic (min.)Advantages:• High short-circuit current, giving large ’start-up window’: unit starts
reliably even with awkward loads (DC-DC converters, motors).
