That means no reset time even at a warm-start. Fuse loading < 2 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) acc. EN 61000-3-2 Transient handling Active transient filter incorporated, so transient resistance acc.to VDE 0160 / W2 (1300 V / 1.3 ms), for all load conditions. Hold up time > 11 ms at 24 V/20 A, Vinnom 24...28 V DC, adjustable by (covered) front panel potentiometer; preset: 24 V ±0.5% Adjusting range guaranteed Output noise suppression Radiated EMI values below EN50081-1, even Silent Switcher ™ when using long, unscreened output cables.

This is done by repositioning a bridge connection (without opening the unit). Reverse power immunity > 30 V Efficiency, Reliability etc.* Efficiency typ. 92 % (24 V/20 A, Vinnom) Losses typ. 42 W (24 V/20 A, Vinnom) MTBF 310.000 h acc. to Siemensnorm SN 29500 (24 V/20 A, Vinnom, Tamb = +40 °C) Life cycle (electrolytics) The unit exclusively uses longlife electrolytics, specified for +105°C (cf. ’The SilverLine’, p.2). High reliability, as • only four aluminium electrolytics and • no small aluminium electrolytics are used. * For further information see data sheets „The SilverLine“, „SilverLine Family Branches“ and mechanics data sheet Order information Order number Description SL20.300 SL20.301 SLZ02 400 V input 480 V input Screw mounting set, two needed per unit sl20e300 / 031001 1/2 Data sheet Output V/I characteristic (typ.) Construction / Mechanics * 32 • WxHxD • Free space for ventilation • Weight 220 mm x 124 mm x 102 mm (+ DIN rail) above/below 70 mm recommended left/right 25 mm recommended 1.8 kg Design advantages: • All connection blocks are easy to reach as mounted at the front panel. • 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.

The V/I characteristic of the supply is straight. Advantages of the switch-on/overload behaviour: • Safer switch-on into highly non-linear loads with large starting currents • Short-term overloads result in current limiting and not in an immediate shut-down. • Parallel operation of several units possible. Proper switch-on performance is obtained.
