With Helios Power Solutions the ability to customise is always an option, ensuring our products meet your every specification, in turn providing a robust reliable and proven solution.
Some areas of customization include

• IP & Seismic rated
• Special terminations/ connections
• Remote monitoring & control
• N+1 Redundancy
• DC Distribution
• Load control & selectivity just to name a few
• Hybrid Solutions ( Modular Rectifiers + inverters + DC/DC Converter for lower voltage requirements in the same application )

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
