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)

(750 V / 1.3 ms), for all load conditions.

Hold up time

> 20 ms at 196 VAC, 24 V / 2.5 A

(see diagram overleaf)

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

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).

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.

Ambient temperature

Operation: -10°C...+70°C (>60°C: Derating)

Storage: -25°C...+85°C

Output protected against short circuit, open circuit and overload

Derating
