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 out-
put voltage can still be adjusted.
• Missing jumper = 'parallel use', i.e. 'soft' characteristic
Power back immunity max. 30V
Housing dimensions and Weight

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 connec-
tion blocks are mounted in the cooler area on the underside of the
unit.
