New 2300-WATT Harsh Environment Power Supplies

2300W harsh environment power supplies

MEAN WELL has expanded the HEP series of harsh environment power supplies to include models with power outputs in the region of 2300 WATTs.



Four output voltages are available: 

  • 55v DC 
  • 115v DC 
  • 230v DC 
  • 380v DC  

The 55v output model is available with 3 connection options: screw terminals, circular connectors (IP66), or wires (IP67). 

The output voltage can be adjusted within a range of 39~57.6Vdc by using the potentiometer adjacent to the connectors on the power supply.  

In addition to this both the output voltage and output current can be trimmed by applying an external voltage signal, allowing these power supplies to be integrated into a higher-level control system. When using this method, the voltage adjustment range is 50~120% of the rated output. The output current can be adjusted within a range of 20~100%. 

The power supply is also available with CANBus, PMBus, or Modbus. Please contact ADM if you are interested in either of these options as a MOQ will apply. 

The power supply can also be set to operate as a battery charger. This is set up by either using the SBP-001 battery charger programmer, or the PMBus or CANBus interface (if available). 

The 115v, 230v, and 380v output models share many of the features that are available on the 55v model. 

The differences are: 

  • Two connection options: screw terminals or wires (IP67) 
  • CANBus & PMBus optional  
  • No battery charger function 

The adjustment ranges using the potentiometer are as follows: 

Rated Output Voltage

Adjustment Range

115v DC

90 ~ 138v 

230v DC

170 ~ 260v 

380c DC

260 ~ 400v 

The HEP-2300 series power supplies are suitable for harsh use in harsh environments where dust, moisture, and high levels of vibration may be present. 

This makes them suitable for many applications including battery charging, communications base stations, in production and process machinery and HF amplifiers. 

All models come with a 6-year manufacturer’s warranty. 

Please contact ADM for further information.
