Recent product introductions include Artisan Controls Model PS-25 Ampere Power Switch; Crouzet 's new TMR 48 range of panel-mounted timers; two new planar transformer series from Pulse aimed at eliminating the need for custom transformers for dc/dc power supplies; and UltraVolt ’s extension of the High Power "C" Series up to 25 kV from the previous maximum of 15 kV.

Artisan Controls Corp . offers the solid-state Model PS - 25 Ampere Power Switch . The PS provides switching of high current loads with a low current switch. User-friendly design provides over-voltage (surge) protection and eliminates relay contact arching and pitting. It can be activated directly from a sensor output switch or an ac output opto-isolator and provides easy installation with quick-connect terminals and an isolated mounting base. Closure of the external control switch energizes the high current load while opening the switch turns it off.

Crouzet 's new TMR 48 range of panel-mounted timers are said to suit applications requiring frequent adjustments where simplicity and ease of use are essential. A large button sets the operating time, which is read directly without the need for conversion or calculation. Based on a microprocessor with built-in flash memory, the TMR 48 also has special functions available on request. Four part numbers provide a total of 18 functions, timing up to 300 hours, and 1 or 2 output relays in 8 or 11-pin versions.

Pulse , a Technitrol Co., introduces two new planar transformer series aimed at eliminating the need for custom transformers in today’s high performance dc/dc power supplies. The two series consist of 45 off-the-shelf catalog parts that can be arranged in 293 different winding configurations. Adding a primary auxiliary winding or a small gap to the transformer expands the number of possible configurations to over 1,000.
UltraVolt Inc . announces extension of the High Power "C" Series up to 25 kV from the previous maximum of 15 kV. New High Power "20C/25C" dc/dc high-voltage converters are designed to deliver 0-20 kV dc and 0-25 kV dc outputs in the smallest possible volume. Each is available in 0-60 W or 0-125 W output. At 47-in. cubed (773 cm cubed), the unit’s high-power density is complemented by high efficiency, tight regulation, low ripple, and good temperature stability, says the manufacturer. Furthermore, the line includes features of the established High Power "C" Series, including fast-rise and low-overshoot capacitor charging.
