Output
AC100-120/220-240 V (switchable), 47-63 Hz
(85-132 VAC / 176-264 VAC, 160-375 VDC, see
also „Output: Continuous Loading“)
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)
DC input current
at open output
typ. 5.3 mA at 110 VDC, 3.9 mA at 300 VDC
(preserves battery sources)
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).
