Teledyne has introduced a high-voltage connector system for use up to 13.5kV and 70,000 feet (21km) altitude. Called DHM, they use the company’s self-contained ‘Hi/Mate’ inserts, pre-wired inside sub-D housings and back-shells – they are only available made-up onto cables. “These inserts leverage Teledyne’s advanced interface sealing system, rendering them suitable for a wide range of aerospace and defense electronic ...

Electrocube has created a series of metallised polypropylene film capacitors for high power inverters in military and commercial, land and sea, applications. Voltage ratings of 400, 600 and 1,000V are available, and capacitances from 100nF to 10μF, plus 15 and 20μ in the 400V range “Able to handle high surge currents without degrading, Electrocube’s 985B is a rugged, non-inductively wound ...

Bourns has introduced a series of gas discharge tubes for protecting equipment against high-voltage surges. The bidirectional GDT28H series has devices with breakdown voltages from 1 to 3.3kVdc, and all are 8mm in diameter and 6mm long, with out without axial leads. Picking the nominally 2kV GDT28H-200 as an example, breakdown is between 1,600 and 2,400V (100V/s). Arc voltage is ...

Amphenol is aiming at vehicles with high-voltage versions of its MicroSpace connectors. “The LV214 Severity-2 compatible connectors are compact, robust and versatile,” according to distributor Mouser, which is stocking the parts. “With a rating of up to 1,200V and 4A, these connectors are suitable for higher power applications, including automotive navigation, infotainment and HVAC clusters.” Selectively-loading a higher pin-count connector ...

Pickering Electronics has announced 125°C versions of its 104 series high-voltage reed relays. 104HT relays will be available in a 1 Form A configuration (SPST NO) rated to stand-off 4kV. Full data has yet to be unveiled but, using the original (-20 to +85ºC) 4kV 104 relays as a guide, switching capacity is likely to be 1kVdc at 25W, and ...

Stackpole has created through hole film resistors that can handle 10kV surges. “For applications with high voltage surge and low energy requirements, they are a viable replacement for carbon composition resistors, providing improved electrical and environmental stability, better tolerance and temperature coefficient, with better long-term availability,” according to the company. Covering values from 560kΩ to 12MΩ, the 10kV surge-rated resistors ...

TDK has introduced a range of 1,200W isolated full-brick dc-dc converter that runs from 200 to 425Vdc for high-voltage dc distributed power architectures. The PH1200A280 range is available with five output voltages: 12, 24, 28, 36 or 48V, with -40 to +20% adjustment to accommodate non-standard voltages. Efficiency  is 94% at 100% load with a 280V input. These converters are 61 ...

In 12.7mm cubes, Advanced Energy Industries has created a range of regulated dc-dc converters that can take in 5V and output up to 600V, depending on version, each one adjustable from 0V to its maximum value. Called the AEQ series, all its members are 500mW converters (250mAin max), with different models giving a choice of outputs: 100V (5mA), 200V (2.5mA), ...

Ideal Power has launched the first commercial version of its novel bi-directional semiconductor power switch, a multi-die module rated at 1,200V 100A (25°C, 50A 100°C) aimed at solid-state circuit breakers (SSCBs) and matrix converters. Updated below to include driving requirements Called IPAM01210C10, “the power module was designed specifically to enable SSCBs to deliver very low conduction losses, while operating orders ...

Essex-based Pickering Interfaces has launched 9kV switching modules for test use, with PXI or LXI interfaces. The 4x-323 PXI and 65-23x LXI ranges include multiplexers and un-committed SPST switch arrays “enabling complex test setups to be implemented,” according to the company. “Hardware interlock is provided on all models in addition to loop-thru ports on multiplexer and matrix products to facilitate ...
