Input over voltage protection: mains up to 350 Vac, for two hours 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 V_out is out of operating range
Output overload protection: the unit automatically reduces the output current to keep the output power below 60W.
Output over voltage protection: shut down of load happens if V_out exceeds 240V
No load operation: the unit automatically switches off.
Over temperature protection: the unit is protected against temporary overheating by automatic reduction of the output current
when tc > 75°C
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;
according to IEC 61347-2-13 Annex J.
Emergency Escape Lighting: this LED power supply is suitable for emergency escape lighting systems acc. to EN 50172
