Power Pulse Modulator
Item Price: £39.99
Quantity Available: 2
This is a multifunction variable pulse generator. It is designed to fit a wide range of applications and be fully adjustable so that it can be used for many different tasks. This is designed to be low cost so that multiple units can be used to complete a variety of tasks, or so that the same board can be used in numerous different projects or experiments where several different devices might normally be needed. The modules can be linked together in a master/slave setup, and the pulse width can be adjusted by an external analogue source.

Need a different spec? Customization available from £14.99 or check below for standard customizations.
Example Applications
Pulse Width modulation (PWM) Motor Speed Control
Pulse Width Modulation (PWM) is used to accurately control the speed of DC motors. The pulse frequency can be adjusted to match your motor for performance or reducing noise. The speed of the motor can be adjusted using the preset on the board, or it can be attached another variable voltage source such as the analogue output from a micro controllers or similar device.
Hydrogen Production (Electrolysis)
Simple control over reaction rates with PWM control. It
can switch large currents for direct connection to
electrodes or use of transformers with widely adjustable
frequency for impedance matching and resonating
systems.
Dimming or Flashing of LED's and Light bulbs
This module can be used to smoothly dim lights or make them flash at regular intervals. The brightness is adjusted by a pulse width modulated signal which can be set to and inaudible frequency.
Tone Generator for small or large speakers
This circuit generates an adjustable square wave signal that is powerful enough to drive anything from piezoelectric sounders to large bass speakers. The frequency range can be adjusted between sub bass and ultrasonic levels.
Transformer Driver
Works with inductive loads like transformers for inverter projects or high voltage power supply's. 12V operation allows it to drive autotransformers, induction or ignition coils.

Solenoid or Relay Pulsing
Simple variable rate on/off function for driving relays or moving solenoids with repeated strokes.
Coil Pulsing
Drive coils and electromagnets with regular current pulses of up to 10 Amps. Ideal for magnetic launchers and many other pulsed coil experiments. At higher pulse frequencies the PWM control can be used to adjust the average field strength of a coil or electromagnet.
SMA Wire Driver
The variable pulse generator can be used as an adjustable current source for powering muscle wire (shape memory alloy SMA wire). By using a medium frequency setting, the PWM control can be used to adjust the average current flowing through the muscle wires giving precise control over the movement. At low frequencies muscle wire can be pulsed for repeated movements.
Transformer Driver
Works with inductive loads like transformers for inverter projects or high voltage power supply's. 12V operation allows it to drive autotransformers, induction or ignition coils.
