Fuji Electric Introduces New High Voltage Power Supply

Fuji Electric Corp. of America has recently introduced a new product in its high efficiency 48V front-end power supply lineup – the FH02000DHV.

This new high voltage DC input (260-400VDC) 2000W power supply is the first of its kind to come with a six position shelf for up to 10KW of redundant power, and provides incomparable efficiency gains for telecom providers.

The new FH02000DHV 48VDC power supply offers 2000 watts with a DC input range of 260-400VDC, operating at an efficiency of 95% @ 50% load. This high efficiency is achieved by enhancing the input, providing a constant input for the phase-shift secondary circuit.

“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 company has introduced the new power supply 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.

Other exclusive features accompanying this power supply include active current share, variable fan speed, DC output over voltage, over-current and short-circuit protection, remote sense, remote ON (News - Alert)/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.”

Mr. Shiina further added that this type of reliability and durability is necessary for the telecom industry, and that they are confident their customers around the world will appreciate Fuji Electric’s high standards for product quality.
