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 90 W . 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.
