PRODUCT UPDATE 29 www.power-mag.com Issue 4 2023 Power Electronics Europe nominal output voltage of 250V DC, adjustable from 180 to 350V DC using the built-in potentiometer, or 100 to 350V DC when using the trimming analogue control function available at the interface connector. The nominal output current is 12A and efficiency is up to 93% at 230V AC input. The use of the company’s digital microprocessor technology results in voltage and current balance control. This simplifies system integrators’ task when connecting units in parallel or series and allows up to 10 power supplies in parallel without adding any other external components. The digital control also controls switching parameters to optimise efficiency, reducing energy consumption. To reduce audible noise the FETA3000BC series is equipped with a thermoregulated fan whose speed is automatically adjusted to optimise cooling according to needs. The FETA3000BC includes in-rush current limiting circuitry, over-current and over-voltage protection and thermal protection. Power Good and Alarm signals are available from the interface panel and highlighted by LEDs. The unit can be remotely controlled via RC pin. The power supply series can be operated within a temperature range of -10 to 70°C, 20 to 90% RH (non condensing), and up to 3,000m (10,000 feet) maximum altitude. Depending on cooling and assembling methods, a power derating may apply. The FETA3000BC includes an input filter and complies with FCC Part 15-A, CISPR32-A, EN55032-A, VCCI-A. In cases where a higher level of conducted noise attenuation is required, the company recommends use of the NAC-20472 filter. The power supply has an input to output isolation of 3,000V AC, input to ground (FG) of 2,000V AC and output to ground (FG) of 2,000V AC. It is UL62368-1, C-UL (CSA62368-1), EN62368-1 safety approved. The FETA3000BC measures 102 x 41 x 340mm [4.02 x 1.61 x 13.39 inches] and weighs 2.3kg maximum for integrated industrial applications in 1U height equipment. Typical applications include measurement and analysis equipment, machine tools, semiconductor manufacturing equipment, battery chargers and power amplifiers. The power supplies comply with the RoHS directive and they are CE and UKCA marked in accordance with the Low Voltage Directive. Medical-grade 6W AC/DC measures 25.6 x 25.6 x 16.6mm The board-mount, through-hole 6W AC/DC converter can be used in a range of applications. It has input nominal voltages of 100 to 277V AC (80 to 305V AC, 120 to 430V DC) making it suitable for worldwide use. Isolation is reinforced/2xMOPP for any application, from household to patient-connect medical, says the company. There is a range of outputs available (3.3V, 5.0V, 12V, 15V and 24V) with high efficiency, maintained down to light loads. Operating temperature is from -40 to 90 degrees C ambient with a full load rating up to 60 degrees C. Full protection is provided against over-temperature, output short-circuits, and over-voltage. Safety certifications include those for IT/multimedia, medical, industrial and household equipment. It also meets Class B EMC specifications with good margin with a floating load. For medical use, touch current is less than 0.1mA for body-floating patientconnect applications. No-load dissipation is 120mW maximum for compliance with eco-design requirements. The RACM06E-K/277 operates at altitudes up to 5000m altitude in overvoltage category II (OVC II) environments to IEC/EN 62368-1 and to 3000m for OVC III according to IEC 61558-2-16. The part is encapsulated with a plastic casingwhich measures 25.6 x 25.6 x 16.6mm. The AC/DC converter weighs just 20g. Parts include a three-year warranty and samples, and OEM pricing is available from all authorised distributors, or directly from the company. The non-isolated DC/DC converter has a fixed 4:1 down conversion ratio and provides 800W continuous, 1.5kW peak output from an industry standard package, measuring just 23.4 x 17.8 x 9.6mm. Input range is 38 to 60V DC (68V DC peak) for an output of 9.5 to 15V DC. The BMR314 is targeted at applications such as powering point of load (PoL) converters in AI and datacomms centres where high peak loads can occur and where space is at a premium but energy saving is important. The converter has high efficiency of 97.4% peak in a low profile package optimised for cold wall cooling. Up to 70A output current is available and the device is protected against over-temperature, input under-voltage and output overcurrent, over-voltage and short circuits. Control and monitoring are provided through a PMBus interface and MTBF is 7.47 million hours according to Telcordia SR-332 Issue 4 Method 1 at 40°C. Operating temperature range is -20°C and 125°C for a specified hot spot location. There is a timed warning and shutdown with over-temperature to minimise stress, particularly under peak loading conditions. The DC/DC converter is available as a surface mount device with LGA terminations and meets the safety requirements of IEC/EN/UL 62368-1 for non-isolated converters and meets ‘Class B’ conducted EMI limits to standards EN 55032/CISPR 32/FCC part 15J with a simple external filter. It is supported by the company’s Flex Power Designer software tool for configuration, performance simulation and monitoring. BMR314 is now available for sampling and is planned to go into volume production in Q4 2023. Nexperia and Kyocera AVX Components produce a 650V SiC rectifier module The 650V, 20ASiC rectifier module for high frequency power applications ranging from 3.0 to 11kW power stack designs is for use in industrial power supplies, EV charging stations, and on-board chargers.
