FReta iEB Series DC/DC Power Modules

The FReta Series offers an industry
standard 200W Eighth brick power module

featuring a high operating efficiency that
results in true useable power. The FReta
modules offer a fixed conversion ratio of 4:1.
The unregulated power train topology
provides a low cost, high performance, high
reliability solution that is suitable for
distributed power architectures that utilize an
intermediate voltage bus to power non­isolated point of load converters.

• Auto-recovering over-temperature
protection

• Applying for UL 60950 (U.S. and
Canada), VDE 0805, CB scheme
(IEC950), CE Mark (EN60950)

• ISO Certified manufacturing
facilities

Optional Features:

• Remote on/off (positive logic)

• Short Thru-hole pins 3.68 mm

(0.145”)
