Regulator offers 95% efficiency & 3MHz switching

Regulator offers 95% efficiency & 3MHz switching
The LTC3124, a 3MHz, current-mode, synchronous boost DC/DC converter, has been introduced by LinearTechnology. Featuring output disconnect and inrush current limiting, the dual-phase converter minimises component size while delivering lower output ripple, versus an equivalent single-phase device. The device's internal 2.5A per phase capable switches together to deliver 5A of switch current.

Thyristor stack controller makes retrofitting easy

Thyristor stack controller makes retrofitting easy
An external thyristor stack controller, called the PLXD, has been introduced by Sprint Electric. Supplied with the latest field bus protocols, the controller can be designed into a new installation or easily retrofitted to an existing thyristor power stack where the control electronics need updating or require adding into a field bus topography network.

Power supply series meets high wattage industrial power demands

In order to fulfill the industrial application demand for higher power product lines, MEAN WELL has introduced the single output 5000W RST-5000 series. The model features the built-in active PFC function, accepting the 3-phase AC input (3Φ 3-wire/△ 196~305VAC or 3Φ 4-wire/ Y 340~530VAC) and provides the output of 24VDC and 48VDC.

AC/DC power supplies offer 3000vac input to output isolation

AC/DC power supplies offer 3000vac input to output isolation
A range of miniature AC/DC power supplies, the PS05 series, has been launched by PowerPax. The 5W PCB mount power supplies, which are IEC60950/EN60950/UL60950 safety approved, features MTBF >300,000 h at 25℃. Measuring 42 x 27 x 11mm, the compact devices occupy very little board space and the class II design offers 3000vac input to output isolation (testing for 1 Min).

75W power supply targets limited width cabinets

75W power supply targets limited width cabinets
To provide solutions for projects in need of the economical 75W DIN rail power supplies, MEAN WELL has launched the EDR-75 and NDR-75 series. With the same dimension and unit width (32mm) of SDR-75 series, these power supplies can be installed on DIN rail TS-35/7.5 or TS-35/15. This makes the series suitable power supply models for cabinets with a limited width.

Flexible DC/DC converter targets hybrid power architectures

Flexible DC/DC converter targets hybrid power architectures
A DC/DC converter, claimed to be flexible, has been launched by GE. The SHHN000A3CL features an input voltage range of 9-36VDC and a bipolar dual output, an output voltage at 15 and -15VDC, 9W output power and a 0.3A output current. The converter can be used as a traditional DC/DC module, powering applications such as insulated-gate bipolar transistors and other semiconductor device drive circuits, or in hybrid power architectures and industrial markets.
