Highly efficient power supply and backup power supply solutions to telecommunications, information and industrial technologies.


PK 300 / PK 600 Thermoelectric Cooling Unit

 General Features

  • Designed for cooling/heating of battery compartments (based on Peltier’s effect)
  • Control unit with a display and buttons to regulate up to 8 modules (with cooling capacity up to 2400W)
  • Maintenance-free and eco-friendly
  • Exterior and interior temperature measurement
  • Low noise and vibration-free
  • Option of DIN rail mounting or 19“ 1U rack mounting
  • Power supplied from an external 48VDC source, from photovoltaic panels or from an auxiliary 230VAC source
  • 2 digital inputs, 2 potential free outputs, or 1 switching potential free output
  • Possibility to connect photovoltaic panels up to 2kWpeak to lower electrical energy consumption
  • PWM power regulation or user-adjustable power steps (100W by default)
  • RS485 remote communication using ModBus RTU protocol
  • Remote control to set the battery compartment temperature, to set the maximum power and to switch Economy mode/Standard mode
  • Modules record and evaluate events in real-time, measure electrical energy consumption of each module and also measure the production of electrical energy from photovoltaic panels
  • Monitoring of fans, PK module failures and exterior/interior temperature
  • LED diode for visual control, full graphic display


    Designed for cooling or heating of telecommunications, security and control technologies placed indoors or in outdoor containers in environments that require an eco-friendly solution and low noise emissions. Allows for connecting of photovoltaic panels and when connected to a 48VDC technology it ensures lower electric consumption.
