![]() Typically save over 30 watts in heat dissipation during transmit, and even 3-4 watts during receive. And lower input voltage means your transceiver will run cooler! When setting the output at 12-volts, input voltages greater than 12V will pass through, but the efficiency of the regulator is higher. The second efficiency enhancement feature is a user-adjustable output voltage control which lets you set the output voltage anywhere between 12- and 13.8-volts. When this feature is enabled, the MFJ-4416 is bypassed unless RF is sensed so no regulator switching efficiency penalties are incurred during receive. Two additional features offer ways to increase efficiency even more! First, there is an RF sampling port which can be connected to your transceiver's transmission line with an MFJ-7733 UHF-T connector. MFJ-4416 also includes output over-voltage crow-bar protection should regulation be lost. This protects you from over-discharging a battery and possibly damaging it. There are also selectable limits on the minimum voltage that the unit will accept: 9-volts, 10-volts (default), and 11-volts. Input fuse protects the unit from excess output current demands. ![]() MFJ-4416 includes Anderson PowerPoleTM connectors and high-current 5-way binding posts for both the DC input and regulated output. And the MFJ-4416 Super Battery Booster is designed to be rugged, reliable, and easy to It is compact at just 7 3/4W x 4H x 2 1/8D” and lightweight at 1.3 lbs. Input voltages as low as 9 volts up to the desired 13.8 volts at up to 25 amps peak with a typical efficiency of close to 90%. The MFJ-4416 Super Battery Booster eliminates low voltage problems by boosting Couple this with any voltage drop in the cables, and you have a problem. Volts to close to 12 volts after a short period of time. For a 100-watt transceiver with a 20-amp typical current requirement, just 1/10th of an ohm resistance in your DC cable and connectors results in a 2-volt drop! And second - when you turn your car off, the battery voltage drops from around 13.8 Resistance DC wiring can result in a noticeable voltage drop. In the mobile environment, low voltage is caused in two ways: First - even low Today's compact 100-watt HF transceivers are designed to operate from about 12-16 volts, with output signal distortion, output power problems, and transceiver reset often occurring when voltage drops below 12 volts. Output Power (Maximum): 400 Watts continuous, 600 Watts intermittently up to 30 sec.Keeps your transceiver operating at full efficiency and performance byĮliminating low or marginal voltages in the mobile environment. Output Voltage: Selectable between 15.5 - 20.0 Volts After start up, voltage boost will be immediate with pressure sensor trigger. ![]() This delay enables the fuel pump to start up with normal system voltage. This allows the engine time to develop manifold vacuum that will remove the voltage boost signal/trigger from the pressure switch during start. The time delay in this version delays boosting fuel pump voltage for 5 seconds on start up. not in vacuum) when the engine is started. ![]() Time Delay version is designed for Naturally Aspirated engines where the manifold pressure is high (i.e. In most cases, this will provide the extra fuel needed without stressing the fuel pump unnecessarily. NOTE: We recommend the 16.5 voltage output unit for most applications. By using this 'voltage boost only under demand' approach, the Flow Charger does not stress the fuel pump when the vehicle is driven under normal, light power loads. When the engine's manifold pressure drops and fueling demand falls off, the Flow Charger returns fuel pump voltage back to standard system voltage. when the engine's fueling demand is high), then the Flow Charger is triggered to deliver the fuel pump the extra voltage needed to deliver the added fuel supply. When the pressure switch closes under higher manifold pressures (i.e. The Flow Charger incorporates an internal high amperage relay to permit system voltage bypass when in normal, non-boost mode operation. The Flow Charger is designed to be installed with a boost pressure switch to trigger the voltage boost mode. This increase is equally applied to both stock fuel pumps or aftermarket fuel pumps. This is particularly useful for increasing the output capacity of the vehicle's fuel pump by 20%, as shipped. Voltage pills are available from 15.5 volt to 20.0 volt in 0.5 volt increments. The actual voltage boost level is set by the selected voltage pill attached to the Flow Charger. It is capable of taking input voltages as low as 10.5 volts and boost the output voltage up to 20 volts. The Flow Charger is a compact, high efficiency microprocessor based voltage boosting unit. ![]()
