Power electronics portfolio showcased at electronica

According to the company, Delta’s Electronically Commuted (EC) Fans deliver lower electricity consumption by 40% to 50% versus traditional AC fans in several applications while Cyntec’s AEC-Q200-qualified power chokes' maximum thickness of 2.1mm supports high-frequency operations of up 1MHz in automotive applications.

“Delta’s core competence of delivering industry-leading energy efficiency is based on its long-term focus in R&D-based innovation and commitment to a low-carbon world. A testament of such endeavour is the official launch, here at electronica 2016, of our new telecom power rectifiers offering impressive efficiency at up to 98%”, said Mr Jackie Chang, President and General Manager for Delta in Europe, Middle East and Africa (EMEA).

Delta’s technologies at electronica 2016 included:

1) Telecom Power Solutions:

1. Their showcase included eco-friendly Telecom Power Solutions by Delta and Eltek. Delta’s DPR3000E-48 series rectifiers now offer leading energy conversion efficiency of up to 98% and power density of 56.8W/in³, qualities to help enable not only further opex and space savings but also lower carbon emissions for our telecom carrier customers. The OutD 'M' series modular outdoor cabinet system includes energy-saving cooling options such as Air Ventilation (AV) only and AV and Air Conditioning (AC). The iF Design Award and Red Dot Award winner 96%-efficient Golden Eagle small cell system for 4G applications was also available.
2. Eltek’s Rectiverter, a bidirectional power module, facilitates optimum simplified AC and DC-powered system structures for higher efficiency, reliability and control and lower total cost of ownership even beyond telecom applications. Eltek also exhibited its Remote Power System and Flatpack S modules at electronica 2016.

2) Power electronics:

1. A growing Industrial Power Supply (IPS) portfolio (currently more than 500 products) offers an extensive set of product types to support power conversion in applications as diverse as factory automation and medical. For example, the high-performance Delta CliQ M series DIN-rail power supply features >90% efficiency and Advanced Power Boost (APB) in a high power density design. The APB function detects a faulty current path within a multiple loads connection and in turn trips the circuit breaker connected to that path, ensuring other connected loads can continue operations without interruption.
2. Delta’s subsidiary, Cyntec, unveiled its next-gen passive components, power modules and RF components at Hall B6, stand 411. For the demanding automotive sector, Cyntec’s miniaturised AEC-Q200-qualified power chokes offer high saturation currents and low DC resistance, are capable of tolerating high-frequency conditions of up to 1MHz and have a maximum 2.1mm thickness and metal dust core.
3. Cyntec also exhibited its advanced 95%-efficiency non-isolated and isolated Point of Load (POL) DC/DC converters which integrate controller chips, chokes and I/O capacitors into a single power management module to deliver up to 75% space savings. These qualities are essential for engineers seeking to construct compact high-performance DC/DC conversion systems.

3) Thermal management solutions:

1. Delta also exhibited its full portfolio of Electronically Commuted (EC) Fans (blowers and axial fans) featuring thermal management with roughly 40-50% energy savings and lower noise operations compared to traditional AC fans in applications such as HVAC, data centres, commercial refrigeration and renewable energy. A wide range of input voltage options available for 3-phase fans (200-480VAC) simplifies the customers’ procurement process substantially. Delta’s EC Fans also offer communication properties for effective speed control and status monitoring via MODBUS RS485 protocol for enhanced energy efficiency and operating reliability.
2. For telecom applications, cabinet thermal solutions, including heat exchangers, thermoelectric coolers, heaters and air conditioners, also leverage Delta’s position in DC brushless fans to maximise operating performance and are capable to run continuously for up to 80,000 hours (nine years). The heat exchangers and thermoelectric coolers also operate with low-noise properties, in some models as low as 54db-A. Delta’s cabinet air conditioners utilise variable-speed DC inverter compressor and dual rotor design to achieve a Coefficient Of Performance (COP) of up to 4.5, meaning lower energy consumption in the cooling process.

4) Uninterruptible Power Supply (UPS) systems:

1. Delta’s 3-phase modular Modulon DPH series UPS system, designed for better flexibility and strong performance with 96% AC/AC efficiency is a suitable option for medium-sized data centres. While a 75kW Modulon system was displayed at the show, its power rating goes up to 200kW. Other UPS systems for IT, industrial and retail applications were part of Delta’s proposition at electronica 2016.
