Variable duty cycle & frequency driver for testing PWM & pulse driven devices.
Professional heavy duty diagnostic tool for driving components that use Pulse Width Modulation (PWM or ‘duty cycle’ control) in their operation. Pulser can also produce pulses of a programmable Hi/Lo duration and count out a set number of these.
Devices that require changing current levels to operate usually have this controlled by varying the 'duty cycle', that is the On:Off ratio is altered (frequency however is fixed). This technique is very efficient for modern vehicle control units to implement.
The drawback for technicians testing these components and systems has been the lack of Hi current driver units to accurately simulate the operation. Not any more, 'Pulser’ can accurately vary the duty cycle and frequency as required to test the operation of a whole range of components.
Pulser also has an auxiliary output that drives a signal out to act as a signal generator for testing power transistors, ignition modules or other devices triggered from a square wave signal. It forms the perfect foundation for injector flow testing or Ignition coil dwell testing (voltage vs time) with our 'Driver Board' accessory if required. The manual provided gives insight into these applications.
It is a powerful and rugged diagnostic tool, countless uses! A small sample of applications that Pulser can be used for -
*The current rating depends on factors such as fuse & wire sizing, speed of switching, temperature etc. The lower the switching frequency, the higher the current capability. Pulser was designed for demanding uses, if you are unsure of it's suitability for your application then please contact us.
