Introduction

DX2625 is a high-efficient self-contained thermoelectric generator block. It harvests waste heat and converts it into usable output DC power. This device is perfect as a stand-alone maintenance-free power supply for wireless sensors and networks (WSN) with its compact size and high-performance conversion ratio. Modular construction, easy-to-mount design and up to 20mW actual power output in natural convection conditions make DX2625 perfect for LED lighting and battery charging applications.  

Power from the harvester is generated by converting heat energy into electrical energy. The amount of generated electrical power depends on the temperature difference between heat source and ambient. In reality, thermoelectric generators are sensitive to ambient conditions. Optimal TEG construction requires a perfect matching of thermal resistances between TEG and heatsink.

The key advantage of DX2625 is its specially optimized and well-balanced electrical and thermal design. TEG efficiency depends significantly on the ratio between TEG electrical resistance and the attached electronics' resistance. Simple at first glance, the TEG energy harvesting idea turns into a complex engineering task with detailed thermal analysis and design. DX2625 is the compact "ready-to-use" TEG energy harvester designed and optimized by specialists in TEG applications. A visually simple solution combines precise TEG estimations, accurate materials matching and high-level engineering. The result is up to 20mW real output power in natural convection conditions. At the same time, the nearest analogs on the market have just a few milliwatts of actual output in the same conditions.

The output voltage of DX2625 can be adjusted by request to accommodate three set points: 1.8V, 2.5V or 3.2V. Another great feature of DX2625 is its modular construction. The PCB inside has a reserved space for integrating customer electronics inside. Thus DX2625 from a pluggable TEG power supply unit can be transformed into a complete "all-in-one" solution based on customer requirements.  

Technically, DX2625 is a high-performance energy harvesting TEG chassis for various applications. This TEG chassis can be modified for a customer application or updated with additional options.

Standard and Advanced Integrating Methods

DX2625 is the complete power supply unit with all electronics on-board.  It's a full set, you just need to plug it in and power your device.  If required it's possible to integrate customer electronic components right onto DX2625 PCB.  It requires a customization, but in this case the device will be turned into a complete stand-alone sealed autonomous system, that can work for decades without any maintanance.
