Detailed description
Detailed description
The MASTERVOLT Series 3 10/30V bilge pump alarm control panel is a dedicated monitoring solution for bilge systems. Designed to operate on 10 to 30-volt electrical systems, it provides reliable signaling in case of bilge pump activation or detection of abnormally high water levels. This product, identified by reference 70403020, belongs to a line that has since been discontinued by the manufacturer.
Product positioning and compatibility
Historically, this panel was part of MASTERVOLT’s offering for essential onboard equipment. Although the Series 3 is obsolete, its operating principle remains relevant for vessels requiring visual and audible control of their bilge pumps. Unlike modern integrated systems such as those offered by brands like B&G or Garmin, which often include bilge monitoring in complex MFDs via NMEA 2000, this panel represents a standalone and direct solution. It differs from newer MASTERVOLT modules or those from competitors like Victron Energy, which prioritize digital integration and advanced connectivity. For a new installation, current alternatives with better integration and extended features should be considered. However, for an identical replacement or extension on an existing compatible system, it may remain a viable option.
Technical specifications and maintenance
The panel is designed for versatile 10 to 30V power supply, making it compatible with most standard marine electrical systems (12V or 24V). Its primary function is to trigger a visual and/or audible alarm, alerting the crew to the bilge pump’s status. The lack of detailed specifications on materials or IP rating prevents precise assessment of its resistance to harsh marine environments, but its MASTERVOLT branding suggests an initially robust design. As a discontinued product, the availability of spare parts or direct manufacturer technical support may be limited, requiring careful evaluation before acquisition for critical installations.
