Commercial Vehicle Product Datasheet SD SERIES HIGH-AMP RELAY Bi-Stable Relay with Auxilary Contacts Features and Benefits Compact footprint saves space in your installation Supports US DOT 11579 and EU ADR requirements for hazmat vehicle compliance Bi-stable internal mechanism draw no current in the on or off state saving your batteries voltage supply Controlled with small wires saving weight and costs of large copper cables Dedicated 24-hour output to power your tachograph or other keep-alive functions Local and remote indication of the state of the relay Description The Littelfuse SD series relay will support your remote power Specifications Overview switching applications that require high continuous current Input Voltage: 9-16V DC passage, large engine starting needs and high ambient temperatures. Primary Contact Voltage: 9-32V DC Additionally the SD series relay helps reduce your costs and Max Continuous Current: 600A saves weight by eliminating the need to route heavy copper cables directly to the mechanical disconnects. Cables can Max Intermittent Current (30 sec) : 1,000-2,000 A instead be routed directly to loads with with the SD series Max Inrush Current (1 sec): 2,000-3,000 A relay positioned close to the battery or in-line with the desired cable routing allowing you to remotely control the unit with a Ingress (IP) Rating: IP66/IP69K fine wire harness.
