Tualatin Valley Labs (TVL), a Portland, Ore.-based designer and manufacturer of test and measurement products, has introduced a voltage sensor designed specifically for combiner box monitoring applications.
The DC1 Voltage Transducer solves a longstanding need for a remote voltage monitoring requirement in solar installations, the company says. With a range of up to 1,000 VDC input and low current requirements, the DC1 can be used for both commercial- and utility-scale applications.Â
The product is designed to convert a DC voltage input to either a 4-20 mA or a 0-1VDC output that is proportional to the input. The transducer provides effective isolation to 4.5 kV and includes safety ratings for both UL and CSA, TVL adds.
