DMS01-VM1-RS12-C

DMS01-VM1 Series Large Format Digital DC Voltmeter PRODUCT OVERVIEW DMS01-VM1-RS12-C is a robust, configurable, digital panel meter that provides precise measurement and display of DC voltage on a highly visible red 1 (25mm) tall, 3 digit seven-segment LED display with adjustable brightness. DIP switches are provided for selectable input voltage range, decimal point placement Independent trim-potentiometers provide additional precision optimization for specialized applications. An external 12VDC power source provides power to the meter and the internal DC-DC converter accommodates a +/-48V common-mode measurement range with respect to the power supply input, simplifying a wide range of measurement applications. The internal digital filter enhances performance in electrically noisy environments. This digital panel meter is ideal for laboratory instrumentation, factory automation, and any application that requiring precise voltage monitoring.

Measurements are displayed with 3-1/2 digits of resolution. A high-impedance input helps maintain accuracy with a variety of signal sources. The meters measurement terminals are electrically isolated from the power terminals through a DC-DC converter, providing a high common-mode input range (+/-48V) for the input (relative to the power terminals), simplifying a wide range of measurement applications. Meter requires external 12VDC power (not included). www.murata-ps.com/support DMS01-VM1.A02.D01 Page 2 of 6
