Helios manufactured a rectifier module in the same physical format as the original 19” modules, facilitating plug-in replacement of the existing modules, retaining existing Nortel frames and site infrastructure.

The aim of this approach was the ability to provide the customer with zero downtime during the replacement of the system, thus significantly reducing the cost and the risks of completely powering down the major IT infrastructure. Anyone in the industry is very well aware that once you power down equipment that runs 24/7 for years, and let it cool down, you can expect with a high degree of certainty that a portion of the equipment will not power back up.

Core Product Integrated into the AMP-K5840

Our design department chose the TDK-Lambda* HFE2500-48 1U DC Power Supply which is one of the most reliable rectifier systems within our range of 1U modular DC power systems. Keep reading the case study of  -48VDC Custom-made Modular Rectifier System for Data Centre

This rugged, industrial quality DC/DC converter uses field-proven topology to generate the required output power. It is built with seven BAP 65 internal modules. Cooling is via built-in fans. Low component count, large design headrooms, and the use of components with established reliability result in a high MTBF. It is manufactured at our plant under strict quality control. BAP5K converter  has a special adjustable output.

It consists of a standard power supply ( HBL2KF-110FT ) with an input of 240VAC and output of 110vdc @ 2KW.

Features

• AC input and DC output on Phoenix connector on rear panel
• Input Circuit Breaker mains power ON/OFF
