Omron has launched a single-pole PCB relay that can break 150A and handle 800V. G7EB-A1-E2 has a 36.7 x 50mm footprint and is 40.2mm tall. Circuit breaking life is 100 operations at 150A 480Vac or 30 operations at 150A 800Vac. “The device is ideal for providing safe system operations with an emergency stop function, and eliminates the need for other ...

Bel Fuse has announced 4kW liquid-cooled dc-dc converter for low voltage accessories in hybrid and electric vehicles. Called 350DNG40-12-8, it can deliver between 10 and 15Vdc from 240 to 450Vdc at up to 93% efficiency with full galvanic isolation between input and output. It features a CAN bus interface (output trimming is via CAN) and IP67 or IP6k9k environmental ratings, ...

XP Power has released two baseplate-cooled dc-dc converter series with 14 to 160Vdc (12:1) inputs. Nominally running from 72V rails, they are rated at 150W (RDF150 series) or 200W (RDF200 series) and designed for use in railway, renewable energy and industrial applications. “The voltages available in railway applications vary globally, often requiring different power designs to suit each geography,” according ...

Colorado-based Advanced Energy has announced a half-brick dc-dc converter capable of delivering 1.3kW at 28V – a continuous current of 46.5A. Called ADH1300-48S28, it is aimed at telecom wireless base stations and other equipment with RF power amplifiers. Input range is 36 to 75Vdc, the output is adjustable across 14 to 33Vdc, and efficiency peaks at 95.5% to keep heat ...

Toshiba has added ten 1.2kV silicon carbide Schottky diodes to its collection, half in TO-247-2L packaging, and half in TO-247, claiming a forward voltage of typically 1.27V. A quick dip in the data sheets reveals that the TRS20H120H drops 1.27V (1.45V max) at 25°C and its maximum current of 20A. This typically rises to 1.64V at 150°C. This is one ...

Leclanché is using niobium-based XNO-branded anode material from Echion Technologies in a lithium-ion cell, aiming it at heavy duty e-mobility, rail and marine use. “We are absolutely delighted to announce the launch of the world’s first commercial XNO Li-ion cell,” said Leclanché CEO Pierre Blanc. “XNO is set to displace the use of LTO within our product line and it ...

Infineon has introduced 135V power mosfets for equipment powered from 72V and 84V batteries. There are 10 of them in a choice of packages: 7pin D2PAK (TO-263), 3.3 x 3.3mm PQFN, SuperSO8, TO-220, TO-Leadless (HSOF-8), TOLG (HSOG-8) or TOLT (HDSOP-16). Rds(on) values range across 2 to 14.3mΩ with 10V on the gate, where gate charge is in the 14.3 to ...
