11.2-kW isolated SMPS that produces 28 Vdc for military apps
Marotta Controls announced the availability and final qualification of the PS11200—the fourth variant in the 1-STEP product line. This switch-mode power supply (SMPS) offers 11,200 Watts of fully isolated output power with 91 percent efficiency at full load. It is designed to replace legacy 400 amp solutions that generally produce unregulated or loosely regulated power […]
Gate-driver boards optimized for high-power modules
Silicon Labs introduced the new Si823Hx Gate Driver Board, an all-in-one isolation solution perfectly suited for the recently launched Wolfspeed WolfPACK power module. Wolfspeed power modules are used across numerous power applications, including EV chargers and motor drives in the industrial and automotive markets. Featuring the Si823Hx isolated gate driver and Si88xx digital isolator with […]
Titanium efficiency 4-kW supplies target OCP, CORD, datacenter apps
Bel Power Solutions announced the TET4000-48-069RAH, a 4000 W power supply designed to provide the highest efficiency (Titanium) power conversion for data centers being built to Open Compute Project (OCP), Open Data Center Committee (ODCC), or Central Office Re-architected as a Datacenter (CORD) standards. The TET4000-48-069RAH is the highest power 48 VDC model in Bel […]
Universal energy harvesting/power management module targets IoT devices
The EHM-UNIV from Xidas is a small surface-mount energy harvesting and power management module that eliminates the need for engineers to purchase energy harvesting evaluation modules and determine how to engineer power management ICs into their application. Xidas has spent over two years working in partnership with the US National Science Foundation (NSF) to address […]
General-purpose high-current, high-voltage power supplies include isolated outputs
Lumina Power has announced the release of the new 10 Channel LPS series general purpose high current, high voltage power supplies for the Electroplating and Specialty Markets. The new 10 Channel Series includes two sets of isolated outputs, with five individual outputs per set. Each set has its own common cathode. The new line consists of 5 […]
PCB power relays meet glow-wire test requirements
Fujitsu Components America, Inc. released a DPST/DPDT 5A PCB power relay series that meets glow-wire test requirements of the IEC/EN60335-1 standard, which addresses the safe operation of consumer and commercial electrical appliances. The low-profile (16.5mm) FTR-F1-GW relay series is rated from 1.5 to 110V. Designed for safety, it features a reinforced insulation construction, 8mm (min) […]
High-power 650V/800V GaN ICs combine power FET and gate driver
Navitas Semiconductor announced the NV6128, a new high-power 650V/800V-rated GaNFast power IC to address the high-power mobile and consumer power electronics market and take market share from the old, slow, silicon chip. The 70 mOhm NV6128 represents a 66% increase in current capability, in a small, 6 x 8 mm PQFN package with a proprietary, […]
Super-efficient power converters help hovering drones take flight
When the task calls for a aerial system that can hover in place, the often-chosen approach is to employ a tethered drone. A tethered drone, generally a multirotor, gets its power and communications signals via a flexible wire or cable. Where battery powered multirotor drones can exhaust their batteries in 20 minutes or so, tethered […]
Compact ac-dc encapsulated power modules target size-restrictive industrial/medical apps
TT Electronics announced the launch of its PAA and PAAM series of AC-DC encapsulated power modules with industry-leading power density, ideal for space-constrained industrial and medical electronic equipment applications. Available in power ratings ranging from 5 to 150 watts, the PAA encapsulated modules are PCB mountable in a compact footprint starting at 1.1” x 1.5” […]
