MEAN WELL Harsh Environment Power Supply Used for Peltier Coolers

Power Supply For Peltier Coolers

Peltier Coolers, also known as Thermo Electric Coolers (TEC) are solid state heat transfers pumps, which are used in a variety of industrial applications to provide cooling.  

ADM was recently able to help a customer supply a remotely controllable harsh environment power supply from stock for this very application.  

The customer needed a power supply that enabled the output current to be controlled by applying an external voltage.  

The MEAN WELL HLG-320H-24B was ideal for this application.  


Although the HLG series power supplies are classified as LED drivers, they can be used with peltiers, because the peltier cooler presents as a replicated diode. 

The HLG-320H-24B has a dimming control circuit, which will accept a 1-10V input. This varies the output of the power supply within the range of 10 ~100%.  

This means the customer was able to control the power supply from their PLC, which receives readings from a set of external temperature sensors and adjusts the 1-10V output accordingly.  

The MEAN WELL HLG series power supplies have a rugged metal enclosure and are fully encapsulated to protect against dust and moisture ingress. In fact, they have an IP67 ingress protection rating. 

MEAN WELL power supplies are world renowned for their reliability and the HLG series comes with a 7-year manufacturer's warranty.
