Solid state relays

Touch-safe units

Three-phase, fully integrated solid state relays, the SSR3PH Series is supplied with heat sink and DIN-rail mounting plate. Designed to switch power to asynchronous motors and resistive loads, they have LED input and dual SCRs. Features include zero-voltage turn-on, 1,200V blocking voltage, 4,000V isolation, and a built-in snubber. The SSR3PH Series is optically isolated. OMEGA Engineering, www.omega.com Enter 603

Ac inverter

Better speed regulation

The MV-4X washdown duty ac inverter series is IP66 and NEMA 4X/12 rated. The units resist chemicals, dust, and forced water, and operate using a front-panel, quick-start keypad. Reportedly compact, easy to connect, and available with a variety of inputs and outputs. Features include RS-485 Modbus RTU for networking up to 32 nodes, and choice of open loop vector control or volts/hertz control. Omron Electronics Inc., www.info.omron.com Enter 604

Power inverter

One transformer for one lamp

The MS Series inverter provides integrated power for large LCD modules. Including fully encapsulated transformers, the MS powers cold cathode fluorescent lamps in LCDs 20 inches and larger. Features include on-board pulse width modulation dimming and cross-talk elimination. Applications include medical diagnostic displays, financial terminals, industrial monitors, and gaming equipment.

Hot swap controller

Programmable supply voltage rate

Hot swap controllers allow boards to be safely inserted into a live backplane. The LT4254 controller handles boards to 36V and features an open circuit detect output that indicates low- or no-load presence. The unit controls the supply voltage ramp-up rate and current to the board within safe levels. Available in commercial and industrial temperature ranges, the LT4254 comes in a 16-lead SSOP package.

Chip scale package

Low-power codec device

The Ultra CSP® chip scale package offers a complete 16-bit codec for surface mounting on a tiny portion of board, the company says. Features standard mounting procedures for increased production over dies and flip chips. The XE 3000 series operates down to 1.8V and uses full duplex PCM and SPI interface. Applications include Bluetooth™ headsets, cordless telephones, and voice storage. Xemics Switzerland, www.xemics.com Enter 607

Light rods

Assorted lengths and diameters

Rod lights for illumination, backlighting, and accent lighting for control panels and test equipment are available up to 36 inches long and 1 inch in diameter. More durable than neon and backlit LCDs, rod lights operate on lower current and use 20–25 mA , the company says. The units are machined, molded, or extruded for custom applications.
