24 volt Smart Battery Isolators

  • Max Charge Current 80 Amps, controlled by the vehicle's alternator.
  • Maximum pass-through current 80 amps (30 minutes) (80 amps is the maximum current that the solid state relay can handle.)
  • Maximum pass-through wattage 1120 watts (see the pass-through current above)
  • Continuous pass-through current 75 Amps
  • Continuous rated pass-through wattage 1060 Watts

This is a solid state relay. It uses state-of-the art microprocessor solid state control of the charging and isolation functions, but uses a solid state relay to control the big currents. There are no moving parts in this unit, so it can withstand harsh operating conditions from -40°C to +50°C. The microprocessor unit constantly scans the voltage level of each of the two terminals for appropriate and timely On or Off connections. It can be used either as a battery low voltage protector or a battery isolator with manual over-ride. This solid state battery isolator uses the latest MOSFET which have the minimal internal resistance of 2mOhm which translates to a total voltage drop of 0.2V even at full load of 80A. It has an idle current consumption of 0.015A. There is no moving parts and the electronic components are conformal coated to give a safe, spark free and long lasting operation in the battery and engine electric environment. This battery-isolator is used to control battery systems that charge off the vehicle's alternator. They won't let the vehicle battery be used to power the load unless the engine is on. It will allow the extra battery to be charged at whatever rate the alternator can put out, so it needs big enough cables to do that. Big lead acid batteries when they are empty can accept 150+ amps, so rate the wires at the maximum current of the alternator (see the QA section below). The features are as follows: First it allows you to safely charge an external lead acid battery from the car electrical bus. It relies on the alternator's smarts to give it a good charge. In this mode it is called a split charge relay, or dual battery relay. Second it allows you to run equipment in a trailer or RV without disconnecting the vehicle power bus. While the vehicle's engine is running all equipment is running from the car's power. When the engine is turned off the trailer equipment is run from the auxiliary battery only. Third, the auxiliary battery can be a deep cycle type designed for running lights, TV, refrigerator, etc. Fourth, it can be used as a low-voltage cutout to keep the car's battery from being drawn below 12.6 volts. Fifth, no external diodes or current sense resistors are needed, the unit is a self-contained solid-state dual battery isolation relay.

Automotive battery backup system. 12 volt DC UPS module keeps 12 volt equipment alive in cars and taxis using an external sealed lead acid battery and acts as a battery back-up (BBU). Click here for 5 amp version with status output Click here for the 12 amp version. Click here for the 24V 12A car UPS controller Complete vehicle UPS with control module and 1.2AH lead acid battery AC input 6V, 12V, 24V, 48V battery backup power supplies This little gadget solves several problems for electronics in cars. First it allows you to charge an external lead acid battery from the car's electrical bus. Second it isolates the extra battery from the car so it won't be discharged by the car electronics, and it won't try to participate in starting the car. Third it powers your equipment in the car using the car electrical system, but switches to external battery power when the car's battery is stolen, or drops below a predetermined voltage. Fourth, it prevents the external battery from being over-discharged, keeping it from being damaged. Fifth, it prevents your equipment from running the car's battery down so the car can't be started. In one configuration it cuts off the car's battery when the voltage gets below 13.1 volts, then switches over to the external battery, in other words it switches over to the auxiliary battery when the engine is shut off and the alternator stops. In another configuration the crossover voltage is lower, say 12.0 volts. This allows your equipment to run off the car's battery but cut off while the car's main battery still has enough power to safely start the engine.

The innovative PST-BP200 uses a leakproof sealed lead acid battery to create a 15 pound portable power source. Includes both AC and car chargers. Battery pack with lighter output. Often we get calls from photographers, astronomers, field researchers, CPAP patients , campers, fishermen and plain ordinary people like us who need a convenient source of portable power to power DC equipment in the field. The BP23 2.3 AH 12V accupack was developed for this purpose, and now the BP-200 extends this to almost 10 times the stored energy, weighing less than 15 pounds (with other configurations that store and weigh less). The charging can be done from an AC outlet or a car, and the output is a female lighter socket output for easy use. This is a package consisting of a 7.5AH to 22 amp-hour, 12 volt sealed lead acid rechargeable battery, a 12V lighter socket output and both an AC charger and a DC car charger. It consists of a tough padded nylon-canvas fabric bag that contains the battery and wiring for charging and discharging. The sealed lead acid battery can be charged or discharged in any position and is completely non-spillable. The charger is in a pouch and can be left home if you don't want to carry it with you. For example, when the portable battery is used with your cell-phone car charger attached the BP-200 can run a typical cell phone for 150 times longer than the battery in the phone, or charge the phone 100-150 times.
