Optimized for harsh environments in industrial/railway applications, the IRQ
DC-DC converter series offer regulated outputs in an industry-standard
quarter brick fully encased package.
FEATURES
PRODUCT OVERVIEW
DC input range: 57.6-160V
The IRQ series regulated converter module
deliver a 5V, 12V or 24V output @ Vin = 57.6
– 160 Vdc in an industry standard quarter
brick fully encased package at astonishing
efficiency. The fully isolated (3000Vdc) IRQ
series accept a 57.6 to 160 Volt DC input
voltage range with a reinforced insulation
system. Typical applications include
industrial, railway and transportation
applications.
The IRQ’s synchronous-rectifier topology and
fixed frequency operations means excellent
efficiencies. A wealth of electronic protection
features include input under voltage lockout,
over voltage lockout protection, output
current limit, current sharing, short circuit
hiccup, Vout overshoot, and over temperature
shutdown.
Available options include various pin lengths
and flanged baseplate. The IRQ series is
designed to meet all UL and IEC emissions,
safety, and flammability certifications.
