Input over voltage protection: mains up to 350 Vac, for one hour maximum, will not destroy both the unit and the load;
shut down of load might occur in this condition.
Output short circuit / undervoltage protection: shut down of load happens if Uout is below 20V (typ. 18V); the unit automatically
tries to switch on the load again every 2-3 s for 0.1 s delivering the selected nominal current.
Output overload protection: the unit automatically reduces the output current to keep the output power below 54 W .
Output over voltage protection: shut down of load happens if Uout exceeds 54V (typ. 55 V); the unit automatically tries to switch
on the load again every 2-3 s for 0.1 s delivering the selected nominal current.
No load operation: the unit automatically tries to switch on the load every 2-3 s for 0.1 s delivering the selected nominal current;
despite this operation mode is safe for both unit and load, it is not recommended. Do not put a switch between load and unit.
Over temperature protection: the unit is protected against temporary overheating by automatic reduction of the output current
when 75°C < tc < 95°C typ., and by automatic power off if 95°C < tc < 100° typ. The protection is self restoring.
Touch current: lower than 0.7 mA, according to EN 60598-1 ann. G and EN 61347-1 ann. A
Switchover time: lower than 0.5 s, both AC and DC mains.
Output power hold time: > 4 ms, in case of mains dips.
Emergency lighting: this LED power supply is suitable for emergency lighting fixtures acc. to EN 60598-2-22;
EOFI = 1% - 100% according to EN61347-2-13 ann J. Continuous output power at ta = 80°C up to 30 W.
