DESCRIPTION
The PD40BJ is a high power, 28 Vdc
Solid State Power Controller (SSPC) with
one square inch package, short circuit
and overload protection, temperature
compensated trip level and very low On
resistance.
These state of the art SSPCs are
designed for use in Power Controller
applications. These SSPCs utilize the
latest technology to provide low On-
resistance output with complete short
circuit and overload current protection.
SSPCs are electronic replacements for
the conventional electromechanical
circuit breakers. The remote features
allow the SSPC to replace these circuit
breakers as well as a load switching
relay. They reduce component count,
system weight and cost and increase
system reliability.
