Efficient heat dissipation means not wasting space for cooling. Phoenix Contact's solid-state Electronic Load Relays (ELRs) feature a large integrated heat sink at the base to deal with heat from switching high-power loads (up to 500V ac at 9A per phase). The devices can be used for motor control with inductive loads up to 4 kW or with resistive loads up to 7.5 kW without contact wear. A 24V dc signal activates the ELR switching circuit. The four types of ELRs can be wired with individual discrete terminations or ribbon-cable connectors used in the company's PLC System Cabling and INTERBUS(TM) systems. Other applications include injection molding, materials handling, and high-speed packaging. Phoenix Contact: Product Code 4311
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
A group of researchers at the Seoul National University have discovered a way to take material from cigarette butts and turn it into a carbon-based material that’s ideal for storing energy and creating a powerful supercapacitor.
