General Description
The Allen-Bradley Bulletin 1606-XLE power supplies are cost optimized
without compromising quality, reliability and performance. Cat. No.
1606-XLE480EP offers high efficiency, electronic inrush current
limitation, active PFC, and a wide operational temperature range.
The small size is achieved by a synchronous rectification and further
technological design details.
The Bulletin 1606-XLE line of power supplies includes all the essential
basic functions. The devices have a power reserve of 20% included,
which may even be used continuously at temperatures up to +45°C.
Additionally, Cat. No. 1606-XLE480EP can deliver approximately 4
times the nominal output current for 15ms which helps to trip fuses on
faulty output branches.
High immunity to transients and power surges as well as low
electromagnetic emission, a DC-OK relay contact and a large
international approval package for a variety of applications makes this
unit suitable for nearly every situation.
