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.
Startup delay typ. 0.2 s
Rise time ca. 20-80 ms, depending on load
Duration of switch-on attempts at
• Initial application
on mains
• Subsequent
attempts
ca. 1.4 s
ca. 0.5 s
Hiccup operation at V
out
< ca. 14 V
Duration between
switch-on attempts
ca. 4 s
Electronic current limiting, protects against overload and short circuit:
•V
out
< ca. 14 V: Periodical switch-on attempts (hiccup-mode).
•V
out
> ca. 14 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.
