Why Buy From Fondriest?


The Extech 160W power supply offers high efficiency electrical power conversion for greater energy conservation and lighter power. It constantly calculates and adjusts the voltage and current limit points according to the available maximum power (160W). At maximum current, 10A, the voltage is limited to 16V, and at maximum voltage, 42V, the current is limited to 3.8A. A dual action rotary encoder control with push knob provides smooth, accurate and quick setting of voltage/current.


Three on-board user-defined voltage and current presets offer quick recall of frequently used test settings. The remote control feature permits output On/Off and voltage/current adjustments without the need to touch the front panel of the power supply. Setting, changing, and verifying the current limit level is convenient and can be performed without output pole spiking. A USB port offers PC connectivity for programming and running ramp/soak cycles with 20 programmable sets of voltage/current and varying test durations, up to 999 cycles. The DC ramp and waveform generator can either be panel set or set by the supplied software which previews the final waveform.


Applications and industries where the DCP42 can be employed include laboratory, telecommunications, production testing, field testing, and DC network powering.

ROV Yogi Gets Underway In Yellowstone Lake

Earlier this year, we covered a work in progress to build a new remotely operated vehicle (ROV) for Yellowstone Lake . It was just an idea back then, but the exploratory craft has since become a reality thanks to some determined researchers and a Kickstarter campaign that reached a goal of $100,000 in funding. Full cost for building the vessel was around $500,000, but crowdfunding a portion of it allowed officials at the Global Foundation for Ocean Exploration (GFOE), a nonprofit engineering group, to spur public interest. In a similar vein, they named the completed ROV “Yogi” in honor of the famous fictional comic book character devised by Hanna-Barbera who gets into trouble at Yellowstone National Park.

Elliott Bay Reconstruction Benefits From Chum Salmon Finds

Like many commercial waterfronts, Seattle’s Elliott Bay has been built to withstand the natural forces of erosion. This has come with the addition of structures like concrete seawalls and piles of riprap, most of which were put in place in the 1930s. But there are a few manmade beaches that have sprung up in recent years along its banks. Some of these have come about because the city is reworking the shoreline following an earthquake that occurred around 10 years ago. And moving forward, Bay planners are looking to add still more improvements, including complexities in seawalls, underwater benches in the intertidal zone and a new beach, all of which are meant to help support fish habitat.

Boise River Watershed Watch Shows Volunteers River Issues

Having just wrapped up its ninth year, the Boise River Watershed Watch program is an increasingly popular citizen science program in Boise, Idaho. It takes interested volunteers and joins them with expert scientists from the U.S. Geological Survey (USGS) who teach them about the river’s health and sampling water quality using transparency tubes, dip nets and chemical test kits. “Our focus is to educate folks on the parameters that we measure, to give them an idea of the river’s health,” said Tim Merrick, public information officer at the USGS’ Idaho Water Science Center. “So they can collect data on the river’s conditions and get plugged in.
