EDISON, N.J. -- April 16, 2013

Fuji Electric Corp. of America has expanded its line-up of high efficiency 48V
front-end power supplies with the introduction of an innovative product for
the telecommunications industry. The FH02000DHV is the first high voltage DC
input (260-400VDC)2000Wpower supply to possess a six position shelf for up to
10KW of redundant power, and offers unparalleled efficiency gains for telecom

“The FH02000DHV is an advanced power supply product with extensive engineering
behind it, and it offers efficiency gains of over 15%,” said Hiroyuki Shiina,
Manager for Fuji Electric’s Power Group. “These types of gains are critical
for telecom providers who are powering 48 DC bus architectures, and both our
power supply and shelf were developed with this goal in mind.”

The FH02000DHV, a 48VDC power supply providing 2000 watts from a DC input
range of 260-400VDC, operates at an efficiency of 95% @ 50% load. This high
efficiency is accomplished by boosting the input, providing a constant input
for the phase-shift secondary circuit. Mechanically, this power supply is
designed for hot-swap applications in a chassis size of 2.73” (69.5mm) wide by
4.86” (123.5mm) high by 12.65” (326.3mm) deep.

Standard design features include: active current share, variable fan speed, DC
output over voltage, over-current and short–circuit protection, remote sense,
remote ON/OFF, over temperature protection, and monitoring of output current
and voltage.

“We are very proud of the extensive feature list for this product,” said Mr.
Shiina. “The power supply has undergone design verification tests, and we were
incredibly pleased that it received a MTBF rating of over 500,000 hours. This
type of reliability and durability is necessary for the telecom industry, and
we are confident that our customers around the world will appreciate Fuji
Electric’s high standards for product quality.”

The FH12000DHV-6PR power shelf can hold up to six 2000 watt power modules, and
can be mounted in a standard 19” rack system using only 3U in height and 19.6”
depth. Each module slot has a separate and isolated DC Input connector, with
all six outputs connected to common DC bus bars. The shelf also provides a
connector for monitoring each of the power module’s I2C and PSMI features.
