Input voltage
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 pow-
er-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 ac-
cessible)
Transient

Transient resistance acc. to VDE 0160 / W2
(750 V / 1.3 ms), for all load conditions.

Efficiency, Reliability etc.*
Efficiency
typ. 86.5 % (230 VAC, 24 V / 2.5 A)
Losses
typ. 9.4 W (230 VAC, 24 V / 2.5 A)
MTBF
700,000 h acc. to Siemensnorm SN 29500
(24 V/2.5 A, 230 VAC, T_amb = +40 °C)
Life cycle (electrolytics) The unit exclusively uses longlife electrolytics,
specified for +105°C (cf. ’The SilverLine’, p.2).

Design advantages:
• Input and output pluggable by means of Combicon® plug connec-
tor.
• 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).
Order information
Rated output voltage 24 V DC
For balanced current sharing during parallel operation:
Soft characteristic (25.2 V DC ±2% at no-load, 24 V DC ±0.5% at nomi-
nal load, almost linear characteristic curve)
Output noise
suppression
Radiated EMI values below EN 61000-6-3, even
when using long, unscreened output cables.
