[ 2 YEAR WARRANTY ]
The LX550 family offers 550 Watts of continuous output power in a low profile
industry standard footprint. Cover and fan assembly and over temperature
protection are fitted as standard. With two standard single output options, and a
flexible standard multiple output, the series can address most power
requirements as standard. The design is specifically tailored to allow full
flexibility, and modifications to meet customer applications can be implemented
with ease. The LX550 AC input series meet the safety requirements of EN60950,
VDE0805, UL1950 and CSA C22.2 No. 950. Input conducted noise levels meet
the requirements of EN55022 class B. LX550 series power supplies are ideal for
use in high power industrial applications and are particularly suitable for front
end power systems.
