Description
The BLP55 Series economical and compact construction provides single or three-output ac-dc power conversion to
meet the requirements of networking and data communications systems, as well as commercial and industrial
configurations.
The BLP55 is rated for convection, as well as forced-air cooling. Full output power is available with external
forced-air cooling. Other features include main-output remote sense and an internal EMI filter.
