The KV12 can control both modes of injection: Saturated and Peak & Hold up to 12 channels.
Peak and Hold Injector Control
- When using low impedance injectors (< 5 Ohms) the ECU uses a switch mode current limiting technique to minimise heat dissipation in the Injector. This gives better injector control and helps maximize injector life by lower its operating temperature.
- Independently configurable Peak and Hold currents
- Flyback Voltage Clamp 70V
- Max Peak current 8A
- Max Hold current 4A
- Total current limited to 10A per output
Saturated Injector Control
- Required when injector resistance is greater than 5 Ohms.
- Flyback Voltage Clamp 70V
- Total current limited to 10A
Auxiliary Injection Mode
- Unassigned Fuel channels can be used to switch or modulate resistive and inductive load.
- Flyback Voltage Clamp 70V
- Total current limited to 10A
- Maximum Frequency: 5kHz
- No internal flywheel diodes. VVT and Idle solenoids require external flywheel diodes
Protection
- Over current / Short to Battery protection
- Electrostatic discharge (ESD) protection
- Flyback Voltage Clamp
The KV12 supports up to 12 Ignition channels.
Ignition Control
- Open collector outputs (low side) with active current source control to produce a logic level signal
- Adjustable Ignition drive current (35mA or 70mA)
Auxiliary Ignition Mode
- When the Ignition output is not configured to drive an ignitor, it can be used to switch or modulate a resistive or inductive load to ground.
- Flyback Voltage Clamp 40V
- Continuous current limited to 1A
- Total current limited to 3A
- Maximum Frequency 5kHz
- No internal flywheel diodes. VVT and Idle solenoids require external flywheel diodes
Protection
- Over current / Short to Battery protection
- Electrostatic discharge (ESD) protection
