BLUE SEA SYSTEMS 3-Bank Dig.Volt Monitor 8-30V – 8051

Description

The Blue Sea Systems Model 8051 is a compact, panel-mounted digital voltmeter designed to monitor up to three separate DC battery banks with precision and ease. Designed specifically for 12V and 24V systems, this voltmeter provides real-time voltage readings from 8 to 30 volts DC, helping you keep track of battery health and ensure your electrical system operates efficiently.

This meter is perfect for marine, RV, and off-grid applications where accurate and reliable battery monitoring is critical. The unit allows users to cycle through three battery banks using a front-panel button and features a bright, easy-to-read LED display.

Key Features:

• Monitors 3 Separate Battery Banks: Ideal for systems with house, engine, and auxiliary batteries.

• Wide Input Range (8–30V DC): Works with both 12V and 24V DC battery systems.

• Digital LED Display: Bright red numerals provide clear voltage readings, even in daylight.

• Low Power Consumption: Designed to minimize current draw from your batteries.

• Simple Operation: Toggle through banks using a single front-panel button.
