Single phase compressor soft starters
Refrigerated display cabinets typically use small piston compressors or scroll compressors. Compressor starts are characterized by a high inrush current (typically 5 to 8 times the rated compressor current) leading to voltage sags especially on single phase installations.
Our RSBS single phase soft startersa2doEQDd90U have a built-in current limit to reduce compressor starting current by up to 60% without requiring any user adjustment. The built-in delays between starts protect against short cycling. conditions. Additional built-in protection function ensure that the compressor is protected even under abnormal operating conditions.

Three phase compressor soft starters
In larger refrigeration applications, scroll compressors and piston compressors are commonly used. In a centralized system, the compressor rack will consist of a series of medium sized compressors. In decentralized systems, smaller compressors are directly installed within the display cabinets.
Whichever solution is used, we provide soft starters that can control compressors up to 100 Aac rated current. RSBTg3QxkF1SirM is tailored for scroll compressors whereas the more general purpose soft starters, RSGD and RSGT are suited for any compressor typology. Most of our soft starters include Modbus RTU to facilitate data exchange with the PLC for real-time load condition monitoring.

Panel mount solid state relays
Refrigeration compressors may be subject to higher ON/OFF switching cycles to maintain the required temperature. Electromechanical contactors and relays might require periodical maintenance and replacement due to contact erosion due to the higher number of switching. Additionally, deployment of flammable refrigerants within refrigeration industry is also requiring a shift to arc free components.
Our solid state relays (SSRs) are finding their way in display cabinets specifically to switch compressors. We offer SSRs in both contactor like design, like RGS as well as hockey puck type enclosure like RM1B.

DIN-rail mount and panel mount energy meters
Energy optimization in supermarket refrigeration equipment should include energy monitoring as a first approach. By monitoring and comparing energy consumption, areas for improvement can be easily identified.
Our DIN-rail energy meters can measure both single phase as well as three phase loads. Various communication protocols are also available to facilitate integration in existing monitoring systems and PLCs.

Controllers for data aggregation
For larger installations, a number of energy meters can be connected to a central controller for data aggregation. UWPObX5k2HLr0w is our universal web platform with remote, on-premise and cloud functionalities.
