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

The CL-51 is an updated, smaller version of the discontinued CL-50.

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

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.

The CL-51 comes with a variety of header connectors and requires soldering. This allows the adaptation of the CL-51 for Fritz-boarding, low profile application, direct attachment to the MFC P2 Cantilever products, or direct attachment of wires.
