DMS01-AM-RS12-C Murata

DMS01-AM Series Large Format Digital DC Shunt Ammeter PRODUCT OVERVIEW DMS01-AM-RS12-C is a robust, highly configurable, digital panel meter that provides precise measurement and display of DC current and supports a wide range of external shunts. DIP switches simplify selection and setup of shunt current / voltage input ranges and features a highly visible red 1 (25mm) tall, 3 4 digit seven-segment LED display with adjustable brightness. Independent offset and scale adjustment trim-potentiometers optimize precision for specialized applications and the internal digital filter enhances performance in electrically noisy environments. An external 12VDC power source provides power to the meter. An internal DC-DC converter accommodates a 48V common-mode measurement range with respect to the power supply input and supports both high or low side measurement, simplifying a wide range of measurement applications. This digital panel meter ideal for laboratory instrumentation, factory automation, and any application that requiring precise current monitoring.
