Input: AC 230V/115V, DC 240-375 V
Output: 24 V/10 A
High overload current, no switch-off
N+1 redundancy, RDY relay contact
Robust mechanics and EMC
Output
AC100-120/220-240 V (switchable), 47-63 Hz
(85-132 VAC / 176-264 VAC, 240-375 VDC)
Note: At DC input, always leave the switch in the 230V position.

< 6 A (switch in 115V position)
< 2.8 A (switch in 230V position)
DCin at open output
8 mA (preserves battery sources)
Inrush current
typ. < 30 A at 264 V AC and cold start
Unit is internally fused (fuse not accessible). External fuse not necessary,
but recommended (common 10A, B-type 'circuit-breaker' switch used
anyway to fuse the input lines).
Transient
handling
Transient resistance acc. to VDE 0160 / W2
(750 V / 1.3 ms), for all load conditions.
Hold-up time
> 25 ms at 196 VAC, 24 V / 10 A
(see diagram overleaf)
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 nominal
load, almost linear characteristic curve)
Output noise
suppression
Radiated EMI values below EN50081-1, even
when using long, unscreened output cables.

short-term also at 60 °C
Output is protected against short circuit, open circuit and overload
Derating

• opens
• Electrical isolation
• Contact rating

Life cycle (electrolytics) The unit exclusively uses longlife electrolytics
specified for +105°C (cf. ’The SilverLine’, p.2).
Start / Overload Behaviour
Start-up delay
typ. 0.1 s
Rise time
(at Tamb=+60°C...+70°C)
ca. 5-20 ms, depending on load
Overload Behaviour
• Special PULS Overload Design (see
diagram overleaf)
• 20% power boost
*
– no disconnection, no hiccup if overloaded
– high overload current (up to 1.6 INom), Vout
is gradually reduced with increasing current.
– 12A short-term, at 45°C or forced cooling
even continuous
For further information see data sheets „The SilverLine“, „SilverLine Family
Branches“ and mechanics data sheet
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
