CL-51 PEH circuit, 3.3V DC or 5V DC output

The CL-51 is an updated, smaller version of the discontinued CL-50. The CL-51 is a PEH circuit for harvesting energy from a broad range of piezo energy harvesters. The CL-51 is available in two versions: either with a stabilized 3.3V or 5V DC output.

CL-54 PEH circuit, dual PEH Input, 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.

EH300A, EH301A EH circuit

The EH300A/EH301A Series EH Modules from Advanced Linear Devices can accept energy from many types of electrical energy sources and store this energy to power conventional 3.3V and 5.0V electrical circuits. EH300A/EH301A Series Modules are completely selfpowered and always in the active mode. They can function with instantaneous input voltages ranging from 0.0V to +/-500V AC or DC, and input currents from 200nA to 400mA.
