IEC60950
Input: 3 AC 400...500V
Output: 24...28V / 960W (1080W)
No switch-off at overload
Ideal for parallel operation
Output for measurement and
logical signals (.301)
Input
Input voltage
3 AC 400...500 V, – 15 %, + 15 %
47-63 Hz, Suitable for IT power systems
340-575 V AC
300-620 V AC
Input current
3.0 A
Inrush current
< 30 A
Inrush current limiting done with a fixed 23R resistor (not a thermistor)
which is bridged after the unit is running, so losses are minimized. That
means no reset time even at a warm-start.
3 A2s
To be fused with a 3 x 10A, B-type 'circuit-breaker' switch based on the
usual thermomagnetic overload sensing principle (used anyway to fuse
the input lines; unit has no internal fuses).

robust screw terminals, connector size range:
• solid: 1.5...6 mm2 (Outp.: 0.5...16 mm2)
• flexible: 1.5...4 mm2 (Outp.: 0.5...10 mm2)
Output: Minus terminal with 2 connectors,
current handling per output: 40 A (max. acc.
to UL) resp. 56 A (max. acc. to VDE)
Design advantages:
• All connection blocks mounted on front panel for ease of access.
• PVC insulated cable can be used for all connections, as the connection
blocks are mounted in the cooler area on the underside of the unit.
• Power density: 230 W per litre housing volume.
Output voltage
24...28 V DC, adjustable by (covered) front
panel potentiometer. Adj. range guaranteed
Output noise

Radiated EMI values below EN 61000-6-3, even
when using long, unscreened output cables.

Front panel indicators: • Green LED on, when Vout > UT, where UT is
ca. 2 V below Vout adjusted (24V...28V)
• Red LED on, when Vout< UT
Parallel operation
SL40.300: yes, no active current sharing
SL40.301: yes, active current sharing, please refer to “Output Signaling” - “Current Balance”
Current sharing by balancing line (active sharing principle, SL40.301) or
’soft’ output characteristic (passive sharing principle, SL40.300; characteristic switch-over by jumper as in SL20/SL30 without opening the unit)

Life cycle (electrolytics)
The unit exclusively uses longlife electrolytics,
specified for +105°C (cf. ’The SilverLine’, p.2).
High reliability and lifetime, as
• only 6 aluminum electrolytics and
• no small aluminum electrolytics are used.
