Input voltage AC100-120/220-240 V (switchable), 47-63 Hz
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

Inrush current typ. < 25 A at 264 V AC and cold start
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 be
mixed up (input below, output above).

Data sheet
Start / Overload Behaviour
Start-up delay typ. 0.1 s
Rise time ca. 5-20 ms, depending on load
Overload Behaviour
• Special PULS Overload Design (see
right diagram)
– no disconnection, no hiccup if overloaded
– high overload current (up to 1.5 I
is gradually reduced with increasing cur-
Nom
), Vout
rent.
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
