Aspen Electronics is to represent APM Technologies (Dongguan) a high-tech enterprise specialised in the R&D, production and distribution of programmable power supplies. Within the Programmable Power Supplies portfolio are DC, AC and Linear designs for applications up to 5kW. All models are cost effective and are characterised by excellent design & build quality.
Assemblies engineered for RF, Ethernet and NEMA power applications
The availability of semi-custom SAFER (Smoke and Fire Exposure Reducing) Cable Assembly Series for RF, Ethernet (RJ45), and power applications has been announced by CDM Electronics. The Low-Smoke Zero-Halogen (LSZH) SAFER cable assemblies are intended for spaces where large amounts of cables are in close proximity to people or sensitive electronic equipment, and anywhere PVC’s combustive toxicity is restricted by fire code.
900V MOSFETs enhance efficiency of flyback converters
Using the latest 900V MDmesh K5 super-junction MOSFETs from STMicroelectronics, power-supply designers can satisfy system demands for higher power and greater efficiency. According to the company, these MOSFETs deliver best-in-class on-resistance (RDS(ON)) and dynamic characteristics. A 900V breakdown voltage assures extra safety margin in systems with high bus voltages. The new series contains the first 900V MOSFETs with RDS(ON) below 100mâ...
Power trends in transportation
Transportation covers a fairly broad field of endeavour, from railway systems through to hybrid electric vehicles, e-bikes, e-scooters and more besides. A focus on energy efficiency is leading to a continuous stream of technology enhancements.
Distribution blocks cut manufacturing time
As sole distributor, Switchtec has introduced the Arnocanali range of distribution blocks. Used to distribute incoming power to smaller or numerous cables within panels, the distribution blocks reduce installation time and keep cable usage to a minimum, providing time and cost savings over traditional methods.
Power device supports compact, high-efficiency BLDC motor drives
Toshiba Electronics has announced a high-voltage intelligent power device (HV-IPD) that will improve the efficiency and reduce the component count of brushless DC (BLDC) motor drives.
300W modules suitable for use in sealed outdoor enclosures
New, higher power models have been added to TDK's PH-A280 series of high voltage input DC/DC converters. Capable of operating from 200-425VDC, these 300W output power modules are suitable for use in data centres, telecommunications and renewable energy applications utilising a 380V nominal high voltage DC bus. The four new models are rated at 12V 25A, 24V 12.5A, 28V 10.8A and 48V 6.3A. This extends the existing 50-150W PH-A280 product range ...
Proportional controllers provide precise power control
Crydom has introduced the PMP series of proportional control relays, designed with microcontroller based technology to provide precise control of the power delivered to a single-phase load, with ratings of up to 90A at 90-600VAC. These solid state relays can control the load power in proportion to an analogue control input, which can be a DC voltage (0-5 or 0-10V) or a DC current (4-20mA); as this control input varies from 0-100% so does the outp...
Drive high current BLDC motors in consumer and industrial applications
A new three-phase brushless BLDC motor controller has been announced by Allegro MicroSystems Europe, for use with N-channel external power MOSFETs. Allegro’s AMT49413 incorporates much of the circuitry required to design a cost-effective, three-phase motor drive system with maximum supply voltages up to 50V. The device is targeted at high current BLDC motor applications for speed, position, or torque control requirements.
Automotive power MOSFET package is 80% smaller
Nexperia has announced the availability of its automotive power MOSFETs in the LFPAK33, thermally-enhanced, loss-free package which has a footprint more than 80% smaller than industry standard devices. LFPAK33 devices also feature a significantly lower resistance responding to growing industry pressure to reduce the size of modules in the car while continuing to improve energy efficiency and reliability.
