nstrating TDK-Lambda’s leadership in digital control is the revolutionary EFE Series. These ultra small embedded front-end power supplies employ a low cost 8-bit microcontroller to achieve full digital control of the output and to handle housekeeping routines; thus replacing the conventional analogue circuitry without the associated cost premium a DSP-based digital solution would bring.
The first products in the range, which visitors to the stand can examine more closely, are the 300W EFE300 and EFE300M and the 400W EFE400 single output supplies. The EFE300M meets the rigorous international safety standards for medical equipment – with 4kVAC reinforced input to output isolation and other specifications such as output to ground isolation of 1500VAC – making it suitable for use in B and BF type medical applications.
The Genesys™ range of rack-mountable, programmable DC power supplies sets a new standard for flexible, reliable, AC/DC power systems for OEM, industrial, ATE, test and laboratory applications. Covering 1U, 2U and 3U formats, they are available from 750W to 15kW and are programmable via GPIB, LAN and USB and come standard with analogue programming.
On display during the show will be TDK-Lambda’s newest addition to the Genesys™ range, the 1U 2.4kW. The full line up of 12 models, includes units with output voltage ratings of 0-8, 0-60, 0-150 and 0-600V. Maximum output current for the lowest voltage range is 300A. The wide range input is continuously variable from 170-265V AC, in both single- or three-phase, and all units feature active power factor correction.
Particularly well-suited to budget conscious applications, TDK-Lambda’s new 25W and 35W models will be on show from its LS Series of convection cooled single output power supplies. These general purpose units are up to 4% more efficient than similar products available on the market today – the extremely efficient design achieves excellent thermal properties and offers higher reliability. The 25W LS25-48 model, for instance, achieves a typical efficiency of 85%. Standard output voltages range from 3.3 to 48V DC, delivering currents up to 7A. To accommodate non-standard system voltages, the LS Series is user adjustable.
