50Amp Complete Constant Current PWM Generator

• 50Amp constant current PWM.
• Complete PWM generator with cooling fan.
• Heavy duty screw type terminals.
• Easy to connect: 12v source, ignition wire and pwm output terminals. Optional water level switch.
• Duty range 0 - 100 %.
• LCD displays : Current (amps), Duty (%), Onboard voltage (Volts), Fan speed (RPM)
• LifeTime Timer to 65000 hours.
• Fan failure detection feature with audible alert.
• No or broken load connection detection feature with audible alert.
• Voltage sensing automatic On/Off. With this feature turned On PWM will not produce current unless the system voltage reached 13.5V which indicates running engine and alternator charging the battery. PWM will turn Off automatically if the voltage reaches 12.0V. This smart feature insures battery is not discharged when car left with ignition in ON position but with engine not running. Both On and Off voltages are configurable by the user.
• Inexpensive water level switch can be attached to PWM to warn you when the water level is low. "Low Liquid Level" message is displayed on the screen with audible alarm. Example of water level switch can be found HERE.
• Multiple PWM modules can be linked together and controlled by one LCD control. This configuration allows to run multiple HHO cells each connected to it is own PWM module.
• Professional looking enclosure with precise one knob control.
• White characters with blue illuminated background LCD display.
• Generator consists of: LCD controller, PWM module and connection cable.
