deutronic battery charging systems computer controlled power supply a regulated battery charger/power supply is absolutely necessary when flashing/programming late model vehicles your transformer based charger is not sufficient for this job don t risk another expensive controller dbl-800 stable battery voltage is critical during programming any fluctuation spiking or loss of voltage will interrupt programming which could cause the controller to lock up or be damaged two critical items are precise voltage control under changing load conditions clean dc ac eliminated since the programming of modules requires the ignition key to be turned on for extended periods without the engine running this means that during the flashing/programming event the vehicle s systems are operating from the vehicle battery alone so a regulated battery charger is critical the deutronic dbl800 helps reduce the risk of damaging control units by providing a continuous stable voltage supply under changing load conditions non regulated power supplies such as transformer based units can cause · mainsac fluctuations being passed on the battery and on board electronics · pulsing current destruction of onboard electronics · low stability of output voltage abort of flash process · superpose alternating current on charging process · cell gassing danger of explosion don t program another ecu without one deutronic_dbl800
