PRODUCT DESCRIPTION
AEM 30-0303
AEM X-Series Voltmeter 8~18V. Black Bezel and Faceplate
The AEM X-Series 30-0303 Digital Voltmeter combines incredible looks, increased readability and a multitude of new, easy-to-use features. It is a must-have for users who want to monitor accurate voltage in their high-performance vehicle.
NOTE: The 30-0303 comes with a black bezel and black 8-18 volt faceplate. For the silver bezel and white faceplate, you will need to purchase the optional 30-0303-ACC accessory kit.
EASIER TO READ
Visual improvements include a bright 87% larger central LED display that is 87% larger than our original digital gauges and provides better readability. A green LED needle sweeps around the edge of the gauge face for quick reference. An overall 33% increase in the gauge display size makes it easier to see at a glance.
EASIER TO MOUNT
Despite the larger display, X-Series Gauges are housed in a standard 52mm (2-1/16") diameter housing for mounting in a standard gauge pod. Thanks to an advanced single-board design, X-Series Gauges have an incredibly slim overall depth of less than 0.825" (2.1cm) with a housing depth of only 0.200" (0.5cm). This shallow housing depth allows X-Series Digital Gauges to be mounted virtually anywhere.
SMARTER INTERFACE
X-Series Digital Gauges include new technological features that make them easier to use. Two buttons on the faceplate allow for programming of peak/recall and data logging on the volt gauge. All X-Series gauges are AEMnet CANbus-enabled, so they can be daisy-chained together for use with the Infinity ECU, Series 2 EMS, AQ-1 Data Logger or any 3rd party EMS or logger that accepts AEMnet. They also include 0-5V analog outputs for data logging into data loggers and engine management systems.
