A Universal Power Alert (UPA) device gives a clear, visual indication of any residual power within an electrical enclosure, leading to higher levels of safety for operating, service or maintenance personnel. The latest UPA-130 model, now available from Marsh Bellofram Europe Ltd, is a smaller unit which has been designed to be fitted in a standard 30mm diameter panel knockout, while the original UPA-100 fitted a 1.1/4” size conduit knockout.

Inertial Aerosystems announce the availability of a new, low cost, 3 axis digital compass module housed in a 9 x 9 x 1.9mm LCC surface package.

LEM has extended its range of current transducer families designed to operate from a single +5V power supply with the introduction of the HMS model. The new unit measures only 16 (L) x 13.5 (W) x 12 (H) mm and integrates a primary conductor. It is directly surface-mounted onto a printed circuit board, reducing manufacturing costs.

In continuing to provide the protective relay market with the newest innovations for replacement units, Basler Electric is offering a microprocessor-based BE1-50/51B-230 as an exact “plug and play” replacement for the obsolete General Electric 12IAC66K relay. You can obtain additional details on the BE1-50/51B-230 from the Plug-and-Play features flyer - ttp://www.basler.com/downloads/5051B_230 flyer.pdf

UNIPOWER's TPCMQ24 series DC/DC bus converters convert 24VDC to either 48 or 54.4VDC for a variety of applications including industrial and telecommunications. Output current is 20.8A at 48V or 18.4A at 54.4V, giving 1000W of total power. These converters operate from a wide range 20 to 30VDC (24V nominal) input with an efficiency of 89% and power density of 12.5W/in³.
