Overview

The Blue Sea Systems 7520 is a wired LED remote panel for Blue Sea Systems P12 battery chargers. It gives you charging status and basic charger control away from the charger itself, using one Cat5e cable for both communication and power. The cable run can be up to 150 ft (45.7 m), the front measures 4.15 x 3.01 in, and the unit draws less than 300 mA from the charger.

On a boat, that makes a real difference when the charger is mounted in a machinery space, locker, or other out-of-the-way spot and you want charger information where you can see it. The display shows charging status, charge stage including PreFloat, equalize status, fan mode, charge output, and alert icons. The four front buttons handle fan settings, display dimming and alarm silence, output limiting, and standby.

Key features

• Works with all Blue Sea Systems P12 battery chargers
• One Cat5e cable carries both power and communications, with cable runs up to 150 ft (45.7 m)
• LED indication for charging, charge stage including PreFloat, equalize, fan mode, charge output, and system alerts
• Four-button control for fan OFF, LOW, or HIGH, display dimming and alarm silence, charger output limiting, and standby
• Surface-mount gasket creates an IP67 seal at the unit face, and the remote is rated for operation from -20°C to 60°C

Installation and fit

This remote is for boats that already have a Blue Sea P12 charger installed. It connects to the charger through the RJ45 port with a Cat5e cable, so there is no separate power feed to run at the panel. The mounting hole cutout is 1-1/4 in (31.75 mm), and the 0.95 in housing depth helps when space behind the panel is tight.

The sealed front face suits cabin, utility-panel, and other onboard locations that may see spray or routine washdown, while the charger itself can stay in a service area. It is a good match for owners who want day-to-day charging status and a few basic controls without opening lockers or working around the charger directly.
