Fuse
L+ / supply voltage
Pin 1
≤ 2 A
Required tripping characteristic of the fuses:
T
fuse
≤ 120 s at max. 6.25 A (fire protection)
Alternatively supply the unit via a limited energy circuit according to IEC 61010-1 or class 2 according
to UL1310.
Output reaction to overload or short circuit:
For self-protection of the output in case of excessive thermal load (due to short circuit or
overload), the output driver starts clocking. If a short circuit / overload continues for several
hours, the driver may be damaged!
u
Disconnect power.
