The GAUTHIER BF454 is an advanced, second-generation Digital Voltage Sensitive Relay (DVSR) 2.0. This automatic charging relay is engineered to combine two battery banks when charging and separate them when not charging, protecting batteries from overcharging or depletion. It supports both DC 12V and DC 24V systems, handling a continuous capacity of 125A and an intermittent capacity of 140A.
Key features include Dual Port Sensing for charging from multiple sources like solar or wind power, and an Easy-to-Configure wiring design using terminal blocks for simplified installation. The DVSR 2.0 automatically detects system voltage and adjusts cutoff thresholds accordingly. It also incorporates delayed open and close timing (15-30 seconds) to prevent unwanted cycling due to voltage fluctuations. With ultra-low standby current consumption (0.3mA at 12V), it is an energy-efficient choice.
Constructed with a durable glass fiber-reinforced nylon enclosure, the BF454 boasts an IP67 waterproof rating, making it suitable for harsh environments, especially marine applications. It meets ISO8846 and SAE J1171 ignition protection standards for safety. The relay offers versatile surface and panel mounting options and has dimensions of 69 mm x 69 mm for seamless integration with other components.
This relay is CE certified, confirming compliance with European safety, health, and environmental protection requirements. YIS Marine also offers a BF454-KIT for DIY installers, including all necessary components for a complete setup.
