Life cycle (electrolytics) The unit exclusively uses longlife electrolytics,

specified for +105°C (cf. ’The SilverLine’, p.2). High reliability, as

• only five aluminium electrolytics and

• no small aluminium electrolytics are used.

Parallel operation Yes, up to ten SL20

To achieve current sharing:

• Plug jumper into pos. 'Output parallel use'. This alters the output V/I characteristic to be 'softer' (25V at 0.4A, 24V at 20A). The output voltage can still be adjusted.

• Missing jumper = 'parallel use', i.e. 'soft' characteristic

Power back immunity max. 30V

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.

Start / Overload Behaviour

Startup delay typ. 0.55s

Rise time appr. 20-80ms, depending on load

Overload behaviour (see characteristic on the right)

• Power Boost: Short-term (<30s) 125% output power without voltage drop.

• Electronic current limiting, protects from overload and short-circuit.

• High overload/short-circuit behaviour (V

<14V) switchable between PULS Over-

out

load Design and hiccup mode. Switching by jumper on bottom of the unit; it is not necessary to open the unit for this purpose.

PULS Overload Design™ (continuous current):

• No disconnection/hiccup, thus overloading is possible also for a longer period of time (load start-up), ideal for parallel operation.

• High overload/short-circuit current due to straight characteristic; each bias point of the V/I characteristic extends 20A.

Advantage: Due to the high and continuously supplied overload current the unit starts reliably even with awkward loads (DC-DC converters, motors). No ’sticking’ such as can occur with fold-back characteristics, and secondary fuses trigger more reliably.

Hiccup mode:

• Unit switches off when high overload occurs (V with subsequent periodical switch-on attempts (hiccup mode):

< appr. 14V)

out

– Duration of switch-on attempts:

appr. 0.1s at short-chircuit or appr. 1s at overload

– Duration between switch-on attempts: appr. 1.5s

•V

> appr. 14V: The output current is continuous. The V/I charac-

out

teristic equals that of the PULS Overload Design™; each bias point of the V/I characteristic extends 20A.
