MECHANICAL DRAWING

Dimensions are in Millimeters

INSTALLATION:

Assembly should be mounted to hot and cold fluid lines

using the provided mounting brackets and M 3 bolts

with a maximum torque of 5.0 in-lbs.

A layer of

graphite has been adhered to the pipe mounting surface

on the EHA-LXXLXX-R01-L1 to ensure a good thermal

contact between the mounting pipe and the EHA

assembly. Performance will vary greatly with ambient

conditions. For best results, insulate the fluid lines

feeding into the assembly. During installation, observe

precautions for handling electrostatic sensitive devices.

Wire Harness

OPERATION CAUTIONS:

For maximum reliability, continuous operation below

85°C is recommended. Do not attempt to disassemble

without contacting a Marlow engineer. Doing so could

result in permanent damage to the TG or other system

components.

IMPORTANT NOTE:

Output from the EH-A-LXXLXX-R01-L1 is strongly a

function of heat source, ambient temperature, and

electrical load downstream of the converter.

Data

given on this sheet is representative of typical system

performance under steady-state flow and thermal

conditions and is intended for selecting the appropriate

EH series assembly. The data should not be taken as

comprehensive or representative of every operating

condition.

For further information about or questions

regarding the EHA-LXXLXX-R01-L1, please contact a

Marlow applications engineer.

AVAILABLE MODIFICATIONS

Marlow can custom design the EH system to maximize power

output, or to meet size, form factor, or temperature

constraints for any thermal energy harvesting application. In

special cases, Marlow can customize units to accommodate

alternating temperature difference or a reverse temperature

difference. Contact an application engineer for more

information.

PIN FUNCTIONS

VOUT (PIN 1)

Main output of the converter.

The voltage at this pin is

regulated to the voltage selected by VS1 and VS2. To select

an output voltage, change the jumper locations at VS1 and

VS2 on the board according to the VOUT Options table below.

Pin 1 may be connected to an auxiliary capacitor. A 220μF

capacitor is already connected to this pin. See Application

Notes sections of this datasheet for more information.
