RS PRO Digital Voltmeter DC, LED Display 1%

RS PRO is proud to offer a series of battery fuel gauges with alarm output. Each battery meter gauge measures the current power available within the battery by monitoring the change in voltage of the device. Our gauge instruments are commonly used with lead-acid batteries and have a 10 bar multi-colour LED display that indicates battery levels.

A 5V/5mA voltage output can be used to activate a suitable audible or visual warning or remove the alarm. These voltmeters have a traffic light indicator status, 1 Red, 2 Yellow, and 7 Green. The display can be set to show only the LED bar corresponding to the current battery state or all LED bars up to the current battery state. An IP65 surface waterproof design is included to adapt to the harsh external environment.

During application, if the ’C’ pin is not connected the LED light bar displays the current-voltage position in a single display.

Connect the ’C’ pin to a positive pole of the power supply, the LED light bar displays the current-voltage position in a multiscreen display.
