Delivering very high operating efficiencies over a wide range of load conditions, the TDK Innoveta iQE Series of Quarter Brick DC-DC converters from Lambda responds to the ever increasing demand for improved efficiency under all normal operating load conditions. With a broad range of output voltages from 3.3 to 15V and providing high power ratings, these DC-DC converters are ideal for engineers seeking excellent efficiency and optimal thermal per...

Dengrove have expanded their product portfolio to include a broad range of DC/DC Converters embodying the characteristically high isolation voltage and extremely small footprint demanded by applications in medical instrumentation.

Excelsys Technologies has introduced the Xqite 900W modular power supply. Measuring just 1U high and 260mm x 127mm the Xqite family of power supplies has been developed for applications that demand low acoustic noise output. Typical noise sensitive markets include audio, broadcast, telecomms and some IT and medical environments. The new Xqite family offers 11W/in³ power density with up to 90% efficiency.

With the ever increasing adoption of IP telephony and the growing abundance of IP devices in general, Power Over Ethernet, or PoE, is seen as a cost effective and in many cases necessary method of powering the deployed equipment. This is particularly true for “always on” devices. Power Over Ethernet integrates data, voice and power on standard Ethernet infrastructure providing many options for power distribution allowing IP telephones...

HARTING has introduced two new families of industrial power supplies to complement its range of Ethernet switches. The pCon 7000 product family, with a high IP 65/67 degree of protection, is designed for distributed applications in harsh environments, while the pCon 2000 is for use in control cabinets.

SynQor has announced an addition to its eighth-brick range of DC/DC converters. The PQ60240EGL03 delivers a tightly regulated 24V output at up to 3A in the DOSA standard 0.9 x 2.3in footprint and pinout. Operating over the input voltage range of 35-75V, the open frame device offers an efficiency of up to 90%. Due to the optimised topology and layout of the device, derating is minimal, even with low levels of forced air cooling. At less than 0.35...

The latest addition to Schroff’s ecopower range of AC/DC switch-mode regulators is a compact 200W plug-in unit that takes up just half the width of a conventional power supply of this performance level and yet is able to achieve an efficiency of 90% using only convection cooling. Particularly aimed at datacom and telecom applications, the new SEC148-200 power supply provides a main output of 48V, together with a battery-charging output of 56V.

AnalogicTech has introduced the AAT1112 and AAT1145, 1.5A and 1.2A constant frequency current mode step-down converters. Available in a small, 3x3mm TDFN package, these current-mode converters require no external compensation components and offer designers highly compact and easy-to-implement solutions.

The Artesyn NLP250 series expands the range of low-to-mid-power solutions available from UR Group. This high-density, high-efficiency switching power supply is only 3.8 cm high with a footprint of just 10.2 x 17.8cm (4x7in) making it suitable for 1U high applications. The range offers up to 250W from 0C to 70C (derating from 50C to 70C) with a typical efficiency of 86%.

MEAN WELL has announced the introduction of a product series for LED lighting. The PLN-30 is a 30W AC/DC enclosed type switching power supply with active PFC function. These limited power sources comply with UL 1310 class 2 that under any situation the output power will less than 100VA or 5A. This will significantly reduce the hazardous condition exposed to the technicians who execute the construction or maintenance of the LED lighting system. Th...
