Santa Rosa, California, May 12, 2011 – Schurter expands its output filter portfolio for improved EMC with the introduction of the 3-phase sine wave output filters, series FMAC SINE and FMAC SINE DCL. The new sine wave filters are designed to convert output voltage wave forms, produced by PWM (Pulse Width Modulation) frequency converters into low distortion sine wave forms. Designed for motor and power transformation applications, the filters increased efficiency and life of the motor. The Schurter sine wave filters are intended for use in 500 VAC installations and currents upwards of 4A.

The FMAC SINE and the FMAC SINE DCL operating voltage is 3 x 288/500 VAC and rated currents range from 4-16A. Both have screw clamp terminals and screw on mounting to the chassis. They are designed for use in motors with power from 1.5 – 7.5 kW, frequency 0-200 Hz and switching frequency of 2-20 kHz. The new sine wave filters allow the use of long, lightweight and cost effective unshielded motor cables. FMAC SINE is optimized for motor cables up to 200 m. The FMAC SINE DCL includes a voltage DC link and efficiently accommodates motor cables up to 1000 m under full load.

The sine wave filters are suited to a wide variety of applications including frequency converters in uninterruptible power supplies, elevators, HVAC systems, conveyor systems and medical equipment. The filters are packaged individually. More information on the FMAC SINE and the FMAC SINE DCL can be found on the Schurter website at http://www.schurterinc.com/new_emc.

Santa Rosa, California, March 9, 2011 - Schurter is pleased to announce a new 2-Pole appliance switch with built-in undervoltage trip release. The new series, dubbed UP1, prevents uncontrolled restarts by monitoring and tripping under conditions of extreme voltage drop, or when the supply voltage is interrupted. Even when the supply voltage returns in full, the machine or equipment does not automatically restart, but must be manually switched on again. Using such a device can prevent harmful situations for operators, as well as others in the surrounding work area.

The UP1 with pushbutton or rocker actuation is a circuit breaker with undervoltage protection, and without overload protection. The pushbutton version is available in both snap-in and screw-on (flange) mounting, while the rocker version is designed for snap-in mounting. IP rated protection covers are offered to prevent ingress of water spray and dust in machinery that operates in harsh environments, such as construction sites, woodworking, metal or masonry shops. The covers can be supplied factory mounted with the breaker or separately for customer mounting.

Applications for undervoltage protection include products such as landscaping equipment, wood chippers, floor cleaning and sanding devices, electrical tools like circular saws, band saws, grinding machines and drills. Other application examples include fuel pumps, coffee-milling devices, fruit juice squeezing machines and fruit juice centrifuges.

The UP1 undervoltage circuit breaker configuration provides a corresponding part number according to switching and mounting features, and supply voltage. The rated switching utilization category is AC-1 16A / AC-3 14.5A @ 115/120 and 230/240 VAC. The UP1 is approved according to IEC 60947-4-1, UL 508, CSA 22.2 No.14-95.
