Quasi-Wide-Range Input: With the switch in the 230V position the power supply unit operates at low and moderate loads (until 3 A) at any input voltage between 95 and 264 V AC.
Note: At DC input, always leave the switch in the 230V position.

To be fused with a 10A, B-type 'circuit-breaker' switch based on the usual 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).

Start / Overload Behaviour

Output characteristic (min.)28

typ. 0.1 s

Rise timeca. 5-20 ms, depending on load

Overload Behaviour• Special PULS Overload Design (seeright diagram)• 20% power boost– no disconnection, no hiccup if overloaded– high overload current (up to 1.9 INom), Voutis gradually reduced with increasing current.
– 6A short-term, at 45°C or forced coolingeven continuous

Advantages:• High short-circuit current, giving large ’start-up window’: unit starts
reliably even with awkward loads (DC-DC converters, motors).
• No ’sticking’ such as can occur with fold-back characteristics• Secondary fuses operate reliably
