R&R Technologies, Inc. (Portland, OR) released its PS-1 Power Supply, a portable benchtop PS with built-in rechargeable batteries that allows engineers to test low-power circuits without cord or power-main limitations, accelerating product development. Engineers can use the battery-operated PS-1 to set up long-term tests that are less susceptible to test-stopping power outages or glitches than corded power supplies. Depending on the test load, the portable PS-1 can run for days on a full charge, facilitate field-testing, and support true power-main-independent testing. R&R's PS-1 works with devices that run at 1.2 to 15 volts in end-user applications and its adjustable-voltage functionality lets engineers test devices at various stages in their lifecycles. The PS-1 includes a three-digit LED display and has an adjustable-current limit of 10 to 1,000 mA. It has a cord and a jack on the front panel to give users the ability to use power mains. The front-panel jack helps prevent the cord tugging that can damage a device being tested and is often associated with back-panel jacks. The PS-1, which retails for $179, shuts off immediately and cuts power to a device being tested when it detects overload conditions; it also alerts users to overload conditions via a beeping alarm and a flashing display light. RS-232 or USB interface options can be added for a $40 fee. For more information on R&R Technologies' PS-1 Power Supply, visit http://www.rnrtech.com/products/power_supplies/ps1.html.
