LX550 SERIES

Flexible single and multiple outputs

[ 2 YEAR WARRANTY ]

• 550W continuous output power

• Industry standard footprint, low profile

• Conducted noise to meet EN55022 class B

• AC and DC input voltage options in same package

• Efficiency up to 88%

• Optional power sharing/VME signals

• Autoranging input

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.
