Efficiency

typ. 90%

(AC 230V, 24V/20A)

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

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.

Efficiency, Reliability etc.*

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.
