It will automatically adjust itself to cover the range of 1.75 to 7 hp. It is fully self-contained in a conveniently small, double insulated and flame retardant enclosure. Soft-starters developed for starting and running single phase scroll compressor motors. Reducing the start current prevents light flickering as well as ensures compressor protection and reduces start up noise.
Automatic adjustment of the starting current to match compressor size and available supply voltage. Contactor protected from arcing damage. LED indicator for any fault diagnosis. Supply line impedance monitoring and compensation for every start. Reduces the supply line voltage drop experienced during startups as well as monitoring supply voltage while the compressor is running to prevent motor stalling during start up or run modes.
Eltwin Hyper SureStart offers a multitude of compressor safety pro- tection features such as: Low voltage protection, reverse scroll detection and overcurrent limit shutdown. They offer significant start current reudction by up to 60-70%.
The customised "PN" option is used to start high inertia loads such as reciprocating compressors and high pressure pumps and offers a start current reduction by up to 20-50%. Models work on 50Hz or 60Hz. 4°F to 150°F (-20°C to 65°C).
5.30" x 2.94" x 1.96 (132mm x 72mm x 49mm). Defrost cycle compatible (Primary Model).
1.75 to 7 hp compressors. Shutdown on Low Voltage (115V). Rated for motors between 1.75 to 7 horse power electrical. Reduces locked rotor amperage (LRA)/inrush current up to 70% at start-up. Reduced stress and heating of compressor/motor therefore extending the life.Easy installation with supplied wiring (special wiring options available). Provides motor reversal protection during short power outages. Internal delay timers prevents rapid cycling in fault conditions. Protects the compressor/motor from stalling at low voltages.
Delay function limits number of motor starts per hour. Avoids torque stress fracture on pipes. Automatic optimization of motor start-up current.
