UPC heat sink

New -- Ultra Power Cooler™ Heat Sink

Solid state relays are semiconductor devices that generate heat in proportion to the quantity of amps being switched. Heat sinks capture that thermal rise and dissipate it. Heat sinks are rated by a ºC/W number that represents: "for every watt of heat generated, the solid state relay will increase by xºC". For example: if you put 30 watts of heat on a 3ºC/W heat sink, the solid state relay's internal SCR dies will rise 90ºC (194ºF) above the ambient temperature. The new, 80 mm (3.15 inches) wide Ultra Power Cooler heat sink provides a 0.2ºC/W rating that makes it ideal for high amperage solid state relays, high ambient temperature areas, or high density installations. Power-io manufactures a variety of heat sinks for industrial, military, or commercial installations. February 16, 2005


90 amp solid state relay

New -- 90 and 125 amp solid state relays

The popular H family of solid state relays has been expanded with two new high current models offering 90 and 125 amp AC switching outputs. The higher amperage models are ideal for high inrush loads or higher amperage switching. When used at lower amperage switching, such as 20-75 amps, these new models offer cooler performance while ensuring a higher margin of safety against amperage inrush problems. Both models have the Maximum Surge Survival™ circuit for outstanding performance and long life in industrial, laboratory, military, or appliance installations. The models use a precision zero crossing method for the lowest possible EMI (noise) without additional filters or other add-ons. Low noise is an international CE requirement as well as a requirement for medical, test equipment, or other precision applications. January 9, 2005
