FEATURES
PRODUCT OVERVIEW
DC input range: 57.6-160V
packaging & thermal management
techniques to deliver a product that meets
critical environmental requirements for
Industrial & Railway applications. The
modules incorporate many features to protect
the power module from fault conditions and
also expensive end use equipment.
Protection features include input under
voltage lockout, output overvoltage
protection, output current limit, short circuit
(hiccup mode) and over temperature
shutdown.
The IRH series delivers the latest technology
in fixed frequency power conversion
designed for Industrial/railway applications.
The IRH series delivers 5V, 12V or 24Vout
from an input voltage range of 57.6V – 160V
with reinforced I/O galvanic I/O isolation
rated at 3,000Vrms. The Half Brick, industry
standard packaging offers options for
electrical connections & mounting for
thermal management in your latest system
designs.
