CL-54 PEH circuit –
dual PEH onput, 
3.3V DC output

The CL-54 was designed to aid in the testing and development of various piezo electric harvesting applications, which are used for the autonomous operation of µProcessors, sensors, and/or IoT systems. With its various features it is also very well-suited for general educational purposes and experiments.

The CL-54 features two PEH A/C inputs, channel 1 and channel 2, which allow harvesting energy of two independent uni-morph PEHs, a bi-morph or a tri-morph PEH. The CL-54 was specifically designed to work with piezo electric energy harvester systems based on the P2 type MacroFiberComposite™. The device will also work with most other types and brands of d31-mode piezo electric energy harvesters.
