The Extech Precision with Programmable 200 Watt Output DC Power Supply has two fixed outputs of 5V and 3.3V.
The Extech Preciion with Programmable 200 Watt Output DC Power Supply has high resolution (1mV and 1mA) user programmable output and voltage protection, and two fixed outputs of 5V and 3.3V. The auto output is of up to 200 steps with programmable voltage, current, and time. The overload delay time is also programmable from 0 to 60 seconds. The dual output terminal allows for source and monitor connections for power with high stability and low ripple and noise. The bi-directional PC interface commands allow setup and readback using the Windows HyperTerminal or similar PC communication programs.
Applications include precision R & D voltage and current source, repetitive production tests using setup recall feature, prototype board initial power-up with overload protection, and general purpose high power lab requirements.

This summer, the team from the Shedd Aquarium in Chicago began pilot programs designed to reach local communities in a new way. Specifically, they ran excursions on both Lake Michigan and the Chicago River using ROVs equipped with underwater cameras and other tools to introduce more land-dwellers to what lies beneath the water.
Shedd Aquarium Learning Programs Manager Sadie Norwick and Communications and Public Relations Coordinator Kayley Ciocci spoke to EM about the Shedd's innovative ROV programming for the public.
Inspiring conservation with technology
Although the pilot programs using the ROVs were new in 2018, the Shedd team is no stranger to using ROVs to educate the public.Read More
This summer, teachers across northwest Ohio took the time to learn about water quality in Waterville at Farnsworth Metropark. The teachers were training in the Maumee River for the Student Watershed Watch (SWW) program , run by TMACOG.
“TMACOG is the Toledo Metropolitan Area Council of Governments, Sara Guiher, a water quality planner and SWW coordinator for TMACOG, explains to EM. “We're a regional planning organization and we work with local governments on issues related to stormwater, wastewater, drinking water, and watersheds. This program started in 1989, and it’s one of our longest running programs.”
The program was designed to foster stewardship through the sampling process.Read More
If you've ever sat at the beach or on the shore of a lake reapplying your sunscreen and wondered what happens to that sunscreen as it washes off in the water, you're in good company. A team of researchers has been investigating how sunscreen chemicals affect marine wildlife, and their recent paper indicates that ultraviolet (UV) filters from sunscreen and other personal care products can affect zebrafish embryo development.
UV filters in the water
Dr. Adela Jing Li's group at Hong Kong Baptist University has been studying UV filters for several years.Read More
