1、This is a multifunctional 12V/24V yacht RV central control modified five‑unit surface plate. It is a kit assembled by five working gauges. It comes with five working meter, oil pressure, water temperature, hour, and voltage, can work simultaneously. 2、Two ignition keys are delivered, which can be used directly. The panel is equipped with functions such as water temperature alarm, low pressure alarm, overspeed alarm, battery charging alarm, light switch, buzzer switch and engine alarm. 3、Install this panel in the central control position of the yacht or RV, and use the data of the instrument to understand the various conditions of your yacht engine and respond in time, which can save installation space and cost. 4、Using post‑programming technology, the driver can be modified as needed to match a variety of analog input signals. Delivered with three matching sensors, can be directly connected to your machine for easy installation. 5、The wire harness connector has a buckle, which can ensure a firm connection between the instrument and the wire harness, even if it is used in strong vibration occasions, it can still work reliably. 6、Using industrial‑grade electronic components and structural parts, the operating temperature can reach ‑30℃‑+75℃. Super waterproof structure design, waterproof and dustproof grade: IP67. 7、The stainless steel front cover is made of 316L, which can be used for a long time even in acid, alkali and humid environments. The whole series adopts ultra-wide working voltage design, long-term working voltage: 9-32V, up to 36V (≤1 minute). 8、Ultra-low power consumption design, the working current of Φ52mm series small meters is ≤60mm, and the working current of 85mm series large meters is ≤100mA. 9、It can be used for engines, generator sets, RVs, yachts, fishing boats, ships, construction machinery, agricultural machinery, modified vehicles and other fields.
