Clever Power CB scheme Data sheet 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 Inrush current 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). Harmonic current emissions (PFC) Transient handling Active transient filter incorporated, so transient resistance acc.to VDE 0160 / W2 (1300 V / 1.3 ms), for all load conditions.

Output voltage 24...28 V DC, adjustable by (covered) front panel potentiometer. Adj. range guaranteed Output noise suppression Radiated EMI values below EN 61000-6-3, even when using long, unscreened output cables.

Over-voltage protection At 32 V ± 10%: switch to hiccup mode 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) Power Back Immunity Efficiency, Reliability etc. * Efficiency 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.

Data sheet Start / Overload Behaviour Rise time Overload behaviour PULS Overload Design (see diagram at the right), thus neither switch-off nor hiccup at overload Advantages: • High short-circuit current, giving large ’start-up window’: unit starts reliably even with awkward loads (DC-DC converters, motors). No ’sticking’ as can occur with fold-back characteristics. • Even longer overload possible as unit does not switch off.
