Unwrapping a cool one

In this article, Relec explores the features, benefits and specifications of Advanced Energy’s LCC1200 ACDC converter series, plus support services underpinning the technology

Advanced Energy’s LCC1200 ACDC converter series is engineered for performance and versatility, suiting applications including catering machines, industrial products, test/measurement equipment, telecommunications systems and more. 

Focussing on efficiency and reliability, Relec states the LCC1200 series employs advanced power conversion to ensure efficient energy transfer, minimising power losses and enhancing overall system performance. The converters are also built to withstand harsh environmental conditions, for reliable operation in demanding industrial settings.

Understanding the differences between conduction and convection cooling is crucial when evaluating power converters. Conduction cooling involves direct physical contact between the converter and a cooling material with high thermal conductivity. Regarding the LCC1200 series, conduction cooling mitigates overheating without fans (which have limited life and reduce system reliability).

Convection cooling relies on movement of a fluid to dissipate heat. This method uses convection currents to carry heat away from the converter. Convection cooling techniques include heatsinks, fans or liquid cooling systems but require additional components and moving parts, adding to noise and cost while reducing reliability.

The choice between conduction and convection cooling depends on specific application requirements and environmental factors. Conduction cooling suits applications where direct contact cooling can be implemented, ensuring efficient heat transfer. The versatility and adaptability of convection cooling suits applications where heat dissipation is managed across a broader system or where conduction cooling is not feasible.

Key specifications of the LCC1200 series include:

Input voltage range: The converters support an input voltage range, typically spanning 85 to 264VAC. This flexibility lets the series accommodate different power sources and voltage variations.

Output power: The series provides a range of power options, with models from 400 to 1200W. This range ensures scalability and suitability for various applications, whether they require low or high-power output.

Efficiency: These converters offer efficiency levels often exceeding 90 per cent. Operating at this efficiency reduces power consumption and minimizes energy wastage, resulting in cost savings and environmental benefits.

Operating temperature: The series is designed to operate reliably across a broad temperature range, with many models functioning in temperatures ranging from -40 to 85°C, suiting extreme operating conditions.

Protections and safety features: The converters are equipped with protection mechanisms to ensure safe and reliable operation, including: overvoltage, overcurrent, short-circuit and over-temperature protection. Integrated safeguards protect the converter and connected equipment, enhancing system longevity and minimising risk of damage.

For Relec Electronics’ customers, the purchasing process starts with a methodical, tailored approach focused on ensuring specific requirements are met. The journey begins with a request via phone, email or webform, which triggers a response from a team of qualified engineers. Rather than selling, the goal is to understand, so before discussing potential solutions, the mission is to comprehend the application’s intricacies.

A standard solution is the starting point. Relec recognises that every project has nuances and unique requirements. Thus, when suitable, initial recommendations are refined. This refinement can introduce bespoke features that add value to the application. This approach ensures the solution isn’t just fit-for-purpose but tailor-made for the customer.
