The **Whisper Power 50214735 - WP-ML Automatic Charging Relay 12VDC** is a high-performance component designed to enhance the safety and reliability of marine electrical systems. This automatic charging relay features a robust 500-amp continuous rating and a bi-stable magnetic latching system that minimizes power consumption in both ON and OFF states. With multiple 22mm cable terminals and a manual override knob, it offers versatile control, even without power, and includes a lock-off capability for safe maintenance. Engineered with silver alloy contacts for exceptional durability, it also boasts an IP66 rating, making it resistant to powerful water jets. Weighing just 0.93 kg, it’s compact yet powerful, with dimensions of 95.25 mm in width, 138.94 mm in height, and 51.56 mm in depth. Designed to combine and isolate battery banks based on precise voltage thresholds, the relay supports a maximum operating voltage of 32V DC, operates continuously below 40mA, and peaks at under 7A when charging. Built to endure extreme marine conditions, the relay operates in temperatures from -20°C to +40°C, with a rugged enclosure finished in RAL9011 graphite black. Additional features include a high cranking rating of 2500A for 10 seconds and 1100A for 1 minute, and durable M10 tin-plated copper terminals, all conforming to strict marine safety standards like CE, ISO 8846, and SA J1171 ignition protection. This relay is an essential addition for anyone seeking reliable and efficient power distribution on their vessel.
