Product Datasheet HD SERIES BATTERY COMBINERS Intelligent Relay Shares Charge Voltage Between Two Battery Banks PN 880051 Specifications Overview Voltage Rating: 880051 - 12V DC 880055 - 24V DC Max Continuous Current: 300A (1x 4/0 input/output cable) Inrush Current Rating: 1500A (1x 4/0 input/output cable) Ingress Protection: IP67/IP69K Operating Temp: -40C to + 85C Description Web Resources Combines battery banks when one is being actively charged, and disconnects them when charge voltage is removed. Supports high-amp intermittent or continuous current loads. Very low quiescent current draw (in On or Off states) due to bi-stable mechanism. Sealed to IP67 & IP69K Download technical resources at: littelfuse.com/HD-Combiner Ordering Information Features and Benefits * Optional remote On or Off switching override enables emergency override for starting from an auxiliary battery, or allows house/cab functions to operate longer in critical applications. PART NUMBER DESCRIPTION 880051 HD Battery Combiner 12V DC 880055 HD Battery Combiner 24V DC * Supports high current loads such as large inverter loads. Operates under high temperature conditions. Compact unit is an ideal choice for applications in heavy vehicles, construction, agriculture, military, mining and agriculture. * Eliminates the cost of routing heavy copper cables to mechanical-only battery switches. Battery combiner can be conveniently located between battery banks, and remote switch can be conveniently located in the cab or wherever required, using only small gauge wiring. * Optional start isolation input ensures isolation of auxiliary loads from engine cranking voltage spikes and sags. * Optional `Engine On' input eliminates relay cycling caused by voltage drop along cables.
