[ 2 YEAR WARRANTY ]
The LX350 series offers 350 Watts of continuous output power in a low profile
industry standard footprint. With two standard single output options and a
flexible standard multiple output version, the series can address most
requirements as standard. The design is specifically tailored to allow full
flexibility and modifications to meet customer applications can be implemented
with relative ease. The LX350 AC input series meets the safety requirements of
EN60950, VDE0805, UL1950 and CSA 22.2 No. 950. Input conducted noise
levels meet the requirements of EN55022 class B. LX350 series power supplies
are ideal for use in applications such as point-of-sale equipment, central and
public telecom power systems and network equipment.
