PIN FUNCTIONS
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.

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.

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

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.
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
