Commercial Vehicle Product Datasheet FlexMod LOW VOLTAGE DISCONNECT Specifications Overview Voltage Rating: 12-24V DC (Auto Ranging) Humidity: 0 to 90%RH Vibration: 10-500Hz Operating Temp: -40 to +85C Ingress Protection: IP67 Dimensions: 4.0 x 2.70 x 1.31 Description Web Resources Preserves battery charge and protects battery banks by Download technical resources at: automatically disconnecting loads when battery voltage drops littelfuse.com/FlexMod to a critical level automatically reconnects when voltage is restored. Protects vehicles with one battery (or bank of batteries). Ideal for single load applications cargo lights, radio, computer, etc. Ordering Information Features and Benefits PART NUMBERS HARNESS DESCRIPTION Senses battery voltage and disconnects non-essential INCLUDED BULK BOXED loads if level falls below programmed voltage. Automatically reconnects loads when battery is charging. 48610 48610-BX Unit Only No Eliminates downtime and vehicle breakdown costs due 48710 Dealer-Programmable Unit No to dead batteries. Overvoltage and overcurrent sensing protects the FlexMod and direct loads. Auto-ranging to automatically sense the voltage of the Accessories system (12 or 24V) and selects the presets appropriate to that voltage. PART NUMBERS DESCRIPTION Waterproof, dustproof and vibration-proof. Sealed to IP67 12805 FlexMod Harness so it can mount on a vehicle even in places where road- splash is a problem. Ultra low 1mA standby current means minimal battery FlexMod Dimensions drain especially valuable when vehicle is in storage or not in use. Factory programmable unit is highly versatile: with a broad range of presets available to match any special application. Rated for more than 1,000,000 on-off cycles unit operates for the lifetime of the vehicle. Solid state technology gives long life and low maintenance. Compact design (4 x 3 x 1) Uses less space mounts outside or inside. Saves money by eliminating other hardware, and provides better wire routing.
