Carlo Gavazzi have enhanced its already popular RSBT 45mm unit, the easy to use and fast to install 3-phase soft starter for scroll compressors from 16A to 32A nominal current and offers Modbus communication.
Fully equipped with an innovative patented self-learning algorithm that automatically adapts itself to the specific compressor it is controlling, ensures an optimum starting current is achieved at every start. The RSBT is a 3-phase controlled solution and is internally bypassed – resulting in less heat dissipation inside the panel and offers enhanced inrush current handling and features internal semiconductor by-pass technology. Field replaceable auxiliary for alarms or Modbus communication modules are available providing much more flexibility.
The unit comes in a 45mm-wide compact format for 16 – 32 Arms or 55 – 95 Arms in 120 mm wide housing for space saving in the panel or DIN rail mounting.
“As energy efficiency regulations continue to drive change towards more intelligent HVAC systems, the benefits of using soft starts to provide real-time energy monitoring and faster fault finding are evident. The compressor is typically the largest energy consumer in a heat pump or chiller and measuring the energy in real time gives the option to monitor the overall system efficiency and our configuration software (SCS) provides a simple graphical view of all the variables that are measured by the RSBT says William Darby, Managing Director.
The RSBT family are the perfect solution for heat pumps, chillers, roof top air conditioning units, refrigeration display cabinet applications.
The RSBT soft starter offers worldwide approval with CE, cULus, CCC, VDE and EAC certification and UKCA pending.
