The **Whisper Power 50214736 - WP-ML Automatic Charging Relay 24VDC** is a robust and reliable solution designed to improve the safety and performance of marine electrical systems. With a continuous rating of 500 amps, this relay utilizes a bi-stable magnetic latching system that minimizes power consumption in both ON and OFF states, making it ideal for long-term use. It features multiple cable terminals with a 22mm stud length and a manual override knob, allowing for safe and convenient control, even during maintenance, by providing a lock-off capability. Built with high-quality silver alloy contacts, the relay offers exceptional durability and reliability, and is IP66 rated for protection against powerful water jets. Compact and lightweight at just 0.8 kg, it measures 95.25 mm in width, 138.94 mm in height, and 51.56 mm in depth, making it easy to install in confined spaces. The relay is engineered to combine or isolate battery banks based on voltage thresholds, automatically engaging when the voltage exceeds 27.0V for 30 seconds or 26.0V for 90 seconds, and isolating when voltage falls below 19.2V or specified values for undervoltage lockout. Supporting a wide range of operating conditions, the relay performs well in ambient temperatures from -20°C to +40°C, with a rugged enclosure finished in RAL9011 graphite black. Additional specifications include high cranking ratings of 2500A for 10 seconds and 1100A for 1 minute, M10 tin-plated copper terminals, and compliance with CE, ISO 8846, and SA J1171 ignition protection standards, making this relay a valuable asset for any vessel.
