TDK-Lambda has introduced the DPX Series of low-power DC-DC converters, which can be rapidly mounted onto DIN rails. Available with both 2:1 and 4:1 input voltage ranges covering 9.5 to 75V and five power ranges from 15 and 60W, the new series provides an economical solution for industrial applications such as process control and factory automation, as well as in alarm and security systems. DPX models are available in single, dual or triple outputs with voltages ranging from three to 15V. For special applications, selected models can be adjusted manually by using a potentiometer mounted on the front panel. Up to three units can be paralleled for higher power applications and typical efficiency is up to 90 per cent. The DPX DC-DC converters are enclosed in a rugged metal case and can be mounted on either a TS35/7.5 or TS35/15 standard DIN rail. A green LED indicator on the front panel gives an immediate visual confirmation of the output status. DPX DC-DC converters feature input re...

Lambda Unveils Fibre-To-Fibre Optical Isolators Lambda Photometrics has announced a line of fibre-to-fibre optical isolators from Optics for Research (OFR). They are designed for use in super-luminescent light-emitting diode (SLED or SLD) applications. These isolators provide high isolation and low insertion loss over broad bandwidths and are available for common SLED wavelength ranges in the 750nm to 900nm region. These isolators use OFR's proven IO-F series optical engine, and two platforms are available for single- or dual-chip SLED requirements. For single-chip SLED applications, the IO-F-SL1 fibre isolator provides high performance over a spectral bandwidth of 70nm. For dual-chip SLED systems, the IO-F-BB-SL2 provides coverage over a 100nm bandwidth. Isolation at the centre wavelength typically exceeds 35dB, and is maintained to at least 20dB at the bandwidth FWHM points for both models. Optical power handling capability is 3W in the forward and reverse directions, and t...
