means no reset time even at a warm-start.

Life cycle (electrolytics)
The unit exclusively uses longlife electrolytics,
specified for +105°C (cf. ’The SilverLine’, p.2).
High reliability and lifetime, as
• only four aluminium electrolytics and
• no small aluminium electrolytics are used.

usual thermomagnetic overload sensing principle (used anyway to fuse
the input lines; unit has no internal fuses).

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 10 V < Vout< UT
• Red LED flashes, when 0 V < Vout < 10 V
Parallel operation
Yes, up to ten SL30 units
To achieve current sharing the output V/I characteristic can be altered
to be 'softer' (25V at 0.4A, 24V at 30A). This is done by repositioning a
bridge connection (without opening the unit).

Electronic current limiting, protects against overload and short circuit:
• Vout < ca. 10 V: Periodical switch-on attempts (hiccup-mode).
• Vout > ca. 10 V: The output current is continuous.
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.

Design advantages:
• All connection blocks are easy to reach as mounted at the front panel.
Input and output are strictly apart from each other and so cannot be
mixed up
• PVC insulated cable can be used for all connections, no thermal
protection is needed
Mounting
on DIN-Rail (TS35/7.5 or TS35/15, 1...1.5 mm thick)
therefore
• Simple snap-on system
• Sits safely and firmly on the DIN-Rail
• No tools required to remove
or backplane-mounted
(two optional screw mounting sets SLZ01 required)
