4 Channel Peak And Hold PH401

$USD 90.0

Out of stock


SPTRONICS Peak & Hold Injector Driver module allows ECU’s that have a saturated injector drive circuit to trigger low impedance injectors  PH401 contains 4 independent injector drive channels. Each channel supplies full battery voltage to a fuel injector for rapid current rise, in order to produce positive injector opening. When the injector is fully opened, the injector driver reduces the load current to required current and operates as a constant current source. This condition holds the injector open, and reduces system power dissipation. 

PH401 supply the low impedance injectors with the full battery voltage for the specific time (injector fully opening time specified by the manufacture) to ensure the injectors is fully opened, then reduce the current to the programmed current  by switching the supply voltage (PWM signal).

  1. hallo
    ik heb 2groepen van 3lpg injectors [2ohm per stuk] , [6cil motor]
    deze 2groepen injecteren afwisselend
    dus 2p&h drivers gaan 3lpg injectoren bedienen,,de ander 2p&h drivers gaan de andere 3lpg injectors bedienen
    kan ik dit board daarvoor gebruiken
    ik hoor het graag van u

  2. Hey
    I have 2 groups of 3lpg injectors [2ohm each], [6 cylinder engine]
    these 2 groups inject alternately
    so 2p & h drivers will operate 3lpg injectors ,, the other 2p & h drivers will operate the other 3lpg injectors
    can I use this board
    please let me know
    Best regards
