P150 SERIES
ENGINEERING DATA SHEET
SOLID STATE POWER CONTROLLER
28 VDC, 1PNO-WITH CURRENT OR VOLTAGE
STATUS OUTPUT
UP TO 30 AMP RATING
DESCRIPTION
The P150 Series of Solid State Power Controllers (SSPC) is rated
from 2 to 30 Amperes. These LEACH SSPC's feature reliable,
trouble free switching together with real short circuit protection.
Employing a power FET output stage, and built using thick film
technology, they offer low on state resistance and low on state
voltage drop. They react to fault condition and can shutdown within
microseconds, if required. Two status signals, derived from the load
current value or voltage and from the device gate, are reported via
optical isolators. Designed to operate in 28 VDC systems, these
devices do not require derating for any load type. They are
hermetically sealed, in a metal package.
