## Overview

The Bolsen TEG1-199-1.4-0.5 is a high-efficiency thermoelectric generator designed to convert heat into up to 10 watts of electrical power. Measuring a compact 40x40x4.2mm, it operates best at a 120°C temperature difference and requires no batteries, making it ideal for industrial and off-grid applications where reliable, clean energy is essential.

## Description

The following data are tested at a constant temperature difference of 120 degrees, the environment is different, the data will be different, for reference only Size: 40mmx40mmx4.2mm Open circuit voltage: 11.1 Volts Matched load resistance: 3.07 ohms Matched load output voltage: 5.6 Volts Output current: 1.8 Amperes Output power: 10 watts Heat flow through modules: approximately 192 watts Heat flux: about 12 watts/cm2

Review: Exactly what I expected! - Well packaged. Haven’t completed the project yet, but these are just what I need.
Review: Okay I like the price, but the picture is misleading - If you aren't expecting it to look this shape by the model number, I hope this picture shows you it looks more like a normal TEC than a TEG, also it's only going to generate about 10watts@190°C temperature difference moving ~190watts thru it. Think about that in your designs.

## Features

- A standard thermoelectric generator, named standard TEG, is the only correct identifier for thermoelectric power generation

## Questions & Answers

**Q: Whats the output and thermal limit?**
A: Output is ambient available heat+watts of power draw, approx 3btus per watt. Upper limit is 180° before you start to do permanent damage. Lower is-80 going below -80 even with the unit off is reported by some people to permanently damage. If they get too hot they permanently lose capacity, if they get too cold I've had them split. Although these particular ones I have been using to heat, from a high ambient so really what's the lower limit about 15°F below the temperature of the fluid you are removing heat from. Move heat from air to water you can predictably get ≤30°∆T.

**Q: Can this device produce cold temp**
A: It moves heat out. It only makes something cooler. I mean technically it can but you have to keep the heat from running right back in.

**Q: What would be the output power (in W) for a temperature difference of about 10 degC? 

What would be the optimum voltage at that point?**
A: I can't tell you the output offhand, but it's not worth buying for only a 10 degree differential usage, at it won't really put that much out. Running a small pc fan on low-med RPM at best.

**Q: What is the maximum temperature this device can tolerate?**
A: Dear,  It can tolerate 200℃ (392℉)

### ⭐⭐⭐⭐ Okay I like the price, but the picture is misleading
*by J***S on June 2, 2022*

### ⭐⭐ Misrepresented in listing.
*by D***N on January 29, 2021*

This is not a TEG. Don’t expect high temperature power generation. Reasonable price for a TEC.
