Mobile UPS 5AH battery backup for 12V equipment in cars, buses and vehicles

Self-contained automotive battery backup system with 5AH battery

12 volt DC UPS module or battery backup (BBU) keeps 12 volt equipment alive in cars, buses, trucks and taxis using an internal sealed lead acid battery. Useful for vehicles with automatic start-stop features.

This DC-UPS contains a 5 amp-hour sealed lead acid battery. It is charged from the vehicle's electrical system and switches your load to its internal battery when the engine is turned off, or at any other time that the electrical bus drops below 11.8 volts. Useful for buses, emergency vehicles, police cars, fire equipment, agricultural equipment, taxi's, van's, boats, trucks, stationary generators and other 12 volt systems.

The Backup-Mobile UPS is designed to keep your equipment from losing power or rebooting during engine start-up, ensuring these spikes and sags in power don't shorten the life of your mission critical electronics. We do this by providing uninterrupted, clean, consistent power to your equipment, extending the life of your electronics up to 2 to 3 more years.

The system prevents your equipment from running the vehicle's battery downavoiding jump-starts. It switches over to the auxiliary battery when the engine is shut off and the alternator stops or the car's battery drops below 11.8 volts. This means you never have to worry about that after-market equipment leaving you with a dead battery in the morning.

The PowerStream Backup-Mobile UPS isolates its battery from the vehicle, so it can't be discharged by the vehicle's other electronics, and it won't try to participate in the engine start-up process.

The DC-UPS powers your equipment in the vehicle using the car electrical system, but switches to external battery power when the car's battery is removed, stolen, or drops below a predetermined voltage, acting as a battery backup (BBU) and power conditioner. It is not necessary to run an extra sense wire to the ignition, voltage sensing takes care of the decision making.

Allows for safely charging our internal battery from the car's electrical bus by isolating and current regulating the connection to the auxiliary battery. Which means you will also get years of faithful service from your Backup-Mobile UPS.

Maximum pass-through wattage	144 watts (180 Watts on special order)
Transient pass-through current	13 amps for 40 seconds 20 amps for 5 seconds Over 20 amps immediate shutdown
The available custom set-points are Main On, Main Off, Charger On, Charger Off, Aux On, Aux Off	This document describes how to engineer and specify the 6 custom set-points if desired
Transition time	less than 50 microseconds from main battery to auxiliary battery less than 50 microseconds from auxiliary battery to main battery. We have a capacitor to keep the voltage up during the transition and have not had any problem with customer's equipment dropping out during the switchover.
Auxiliary battery charging starts when main voltage is:	Factory selectable, default is 11.8V
Internal battery	5AH Sealed Lead Acid battery
Charge algorithm	Constant current until the battery voltage reaches 13.4 volts, taper charge above 13.4 volts to zero current at 14.1 volts
