eysight Technologies has introduced a new high current ultra low noise filter for the B2961A and B2962A 6.5 Digit Low Noise Power Source that can supply up to 500 mA while maintaining 10 µVrms and 1nVrms/Hz (at 10 kHz) noise performance. With a starting price of less than $10K, the B2961A and B2962A are the world’s only low-cost standalone power sources capable of sourcing at ultra-low noise levels. These products help researchers, electronic development engineers and electronic technicians to meet their most difficult measurement challenges during device development and evaluation. Keysight’s B2961A and B2962A deliver the best-in-class precision and extremely low noise floors that today’s design engineers researching and developing AD/DA converters, VCOs, sensors and
transducer devices demand. Such devices often require wide current and voltage coverage with low noise. With its new ultra low noise filter, the B2961A and B2962A can now output up to 500 mA while still maintaining an extremely low-noise floor of 10 µVrms and 1nVrms/Hz (at 10 kHz). These capabilities make it the ideal precision source for use with other instruments such as network analysers, signal source analyser and nano-voltmeters. Most signal source analysers, even those with a built-in source, cannot simultaneously supply a low-noise voltage output at the current levels needed for many engineering applications. However, the B2961A and B2962A’s new high current ultra low noise filter meets both of these requirements.

Revolutionary SCALE-iDriver ICs from Power Integrations introduce high-reliability SCALE-2 driver technology to 1200 V applications
A
family of galvanically isolated single- channel gate driver ICs ranging in output current from 2.5 A to 8 A,
which is the industry’s highest output current without an external booster, has been announced by Power Integrations. SCALE-iDriver ICs, optimised for driving both IGBTs and MOSFETs, are the first products to bring Power Integrations’ pioneering FluxLink magneto-inductive bi- directional communications technology to 1200 V driver applications. FluxLink technology eliminates the need for unreliable opto-electronics and the associated compensation circuitry, thereby enhancing operational stability while reducing system complexity. In addition to combining industry-leading isolation technology, the new gate drivers incorporate advanced system safety and protection features commonly found in medium- and high-voltage applications, further enhancing product reliability. The innovative eSOP package features 9.5mm of creepage and a CTI of 600, ensuring substantial operating voltage margin and high system reliability.
SCALE-iDriver single-channel gate driver ICs dramatically reduce component count for inverters up to 110 kW, saving space and BOM cost and increasing design flexibility. With the addition of a simple, low-

agna-Power Electronics has released its MagnaLOAD product line of DC electronic loads
spanning 1.25 kW to 120 kW+. The new product line includes three product series, ALx Series, ARx Series, and WRx Series spanning 39 air- and water-cooled models from 1.25 kW to 120 kW+ with voltage ranges up to 0-1,000 Vdc and current ranges up to 0-1,200 Adc. The MagnaLOAD product line launches with Magna-Power’s all new distributed DSP architecture, MagnaLINK, featuring digital control loops and an internally developed high-speed product-to-product communication protocol. The MagnaLOAD product line is designed to dissipate DC power during development, manufacturing, and validation of DC sources, including power supplies, DC-DC converters, batteries, solar panels, fuel cells, motors, and electromagnets. The ALx Series MagnaLOAD, 1.25 kW and 2.5 kW, utilises conventional linear MOSFET-based dissipative elements, allowing the series to achieve a very wide voltage-current operating range within a model’s maximum power rating. Using the same heat management innovations developed for Magna-Power’s high density programmable DC power supplies, the ALx Series’ conservative
cooling ensures long product life in environments up to 50°C ambient operating temperatures.
The ARx Series MagnaLOAD, 7.5 kW to 45 kW+, introduces Magna-Power’s patent-pending Active Resistance Technology, combining a binary switched resistor network in series with linear elements. Used in conjunction with the new MagnaLINK DSP controller, the ARx Series achieves 16-bit programming and measurement resolution and, as a result of the Active Resistance Technology, at a fraction of the price of traditional electronic loads.
The WRx Series MagnaLOAD, 15 kW to 120 kW+, also utilises Magna-Power’s new Active Resistance Technology in combination with the company’s newly developed internally manufactured microchannel water-cooled heatsinks. Designed for high-power applications where heat-flow control is essential, the WRx Series greatly increases power density compared air-cooled alternatives. An integrated solenoid controls the flow of water to avoid condensation. Full power can be achieved using conventional water with water inlet temperatures up to 25 C.

High efficiency AC-DC power modules have ratings up to 1000W
cost booster stage, it is now far quicker to develop efficient, space-saving, reliable inverter designs rated up to 400 kW (15 A). The new devices meet the IEC 60664-1 and the IEC 61800-5-1 standards, and operate from -40°C to +125°C and at frequencies of up to 250 kHz. They also feature Power Integrations’ Advanced Soft Shut Down (ASSD) mechanism that protects the power semiconductor switch in the event of a short circuit. ASSD is automatically triggered by monitoring desaturation levels and requires no extra components. Scale-iDriver ICs suit applications in industrial drives, power supplies and ups, photovoltaic inverters of all sizes, industrial HVAC, EV charging and traction equipment including commercial EVs.

DK Corporation announces the introduction of the PFE1000FA series of power modules,
representing a significant upgrade to the PFE1000F launched eight years ago. The new series offers efficiencies as high as 90 per cent, an improvement of up to four per cent. Rated between 720W and 1000W, the products are designed for use with a cold-plate where cooling fans are not permitted, including industrial, MIL-COTS and communications applications. The PFE1000FA is available with nominal output voltages of 12V, 28V and 48V that can be adjusted over a ±20 per cent range for non-standard voltage requirements. The series accepts a wide range 85 to 265Vac input and can operate at full load with baseplate temperatures of between -40 and +100°C.
Having the same pinout and package dimensions as the original series, 100 x 13.4 x 160mm, the new series can easily be used to upgrade existing designs, offering up to 30 per cent lower losses and reduced operating temperatures. Input current wave-shapes have been improved to be more sinusoidal, allowing the PFE1000FA to meet the harmonics standard IEC 61000-3-2 with even greater margins. All models feature remote on/off, an opto-isolated module good signal, single wire current sharing and a 12V 20mA standby voltage as standard. The PFE1000FA modules are safety certified to IEC/EN/US 60950-1, with CE marking for the Low Voltage and RoHS2 Directives. The series now carries an extended warranty of five years.
