Input over voltage protection: mains up to 280 Vac, for 2 hours maximum, will not destroy both the unit and the load;
shut down of load might occur in this condition.
Output short circuit / under voltage protection: shut down of load happens if Urated is below 7.5V (typ. 6.5V); the unit
automatically tries to switch on the load again every 4-5 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 18W .
Output over voltage protection: the unit tries to stabilizes the voltage by reducing the current as necessary down to 50%, if Urated
still exceeds 54V (typ. 56V) a shutdown will occur; the unit tries automatically to switch on the load again every 4-5 s for 0.1 s
delivering the selected nominal current.
No load operation: the unit automatically tries to switch on the load every 4-5 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 (up
to a complete power off) when tc > 75 °C (typ. 85°C). The protection is self-restoring.
Touch current: lower than 0.7 mA, according to EN 60598-1 ann. G and EN 61347-a 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
