LIST OF AC & DC CUSTOMISED POWER CONVERSION SOLUTIONS

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.

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

Each of the cabinets operate as stand-alone systems but the control and integration of the Bravo modular inverter system into the 110VDC Cordex system is in CAB909. The 24VDC and 110VDC distributions can be combined into one 24VDC and one 110VDC distribution by switching on the bus combining breakers in both cabinets. Each charger within the individual cabinets is connected to its own dedicated battery bank—specifically, a 24Vdc (BR157) and a 110Vdc (BR158) external battery bank.

To ensure redundancy and reliable operation, each of the battery charging systems, both the 24VDC and the 110VDC, is equipped with a blocking diode on the output. This configuration guarantees seamless and uninterrupted operation in conjunction with the charger located in CAB 909/1. Notably, both CAB909 and CAB 909/1 are designed with three independent power inputs: two 400VAC inputs to power the chargers and one 230VAC input for the inverter system, which benefits from a dual input option (AC + DC).

Application: This robust and versatile system has been successfully deployed in a geothermal power station situated in New Zealand, where it plays a crucial role in powering and safeguarding a range of mission-critical loads, including protection circuits, control systems, communications infrastructure, and instrumentation.
