Output short circuit / undervoltage protection: shut down of load happens if Uout is below 15 V (typ. 12 V); the unit automatically tries to switch on the load again every 1 s for 0.5 s delivering the selected nominal current. Output overload protection: the unit automatically reduces the output current to keep the output power below 35W . Output over voltage protection: shut down of load happens if Uout exceeds 54V (typ. 55V); the unit automatically tries to switch on the load again every 1 s for 0.5 s delivering the selected nominal current. No load operation: the unit automatically tries to switch on the load 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. The protection is self restoring. Touch current: lower than 0.7 mA, according to EN 60598-1 annex G and EN 61347-2-13 annex A. Max. 2 ECG per luminiare, each ECG supplying separately its load (two or more units cannot be connected together on secondary side). Switchover time: typical 0.6s, both AC and DC mains. Output power hold time: ≤ 2 ms, in case of mains dips. Emergency lighting: this LED power supply is suitable for emergency lighting fixtures acc. to EN 60598-2-22, with emergency output factor EOFI = 0,15 ( default value, can be programmed up to EOFI = 1) and related duration time of 10 h at least. Function in emergency is ensured up to ta = 80°C and tc = 92°C. HOT Plug: connection of LED on secondary is allowed without damage of LED. LED turns on automatically Standards Ordering information EN 61347-1 Product name Type EAN10 EAN40 NAED EN 61347-2-13 OTi DALI 35/220-240/1A0 LT2 AA62433 4052899919440 4052899919518 n/a EN 55015 OT Cable Clamp B-style 4052899077898 Pieces / box 20 20 EN 61547 EN 61000-3-2 EN 62384 EN 62386 Disclaimer (Engineering Samples) This product is a demonstration model from our development laboratories made available for your information only.
