The RVMS100S-16A integrates compressor in-rush current over startup time, thus reducing peak current demand on a power supply source (generator or other). If you increase the initial voltage it will help the imbalance but you also don't get a very soft starter. Voltage regulator or resistors to change voltages for motors? Soft starter is the one which slowly changes the applied voltage to an induction motor which results in reduction of electrical surge current of motor during starting. A motor soft starter is a device used with AC electrical motors to temporarily reduce the load and torque in the powertrain and electric current surge of the motor during start-up. This also means you need a delay between the compressor starting/stopping to allow the pressure to equalize.

Once your order is processed, well send one of our professional service technicians to your home to install the soft start unit inside your Dandelion Geothermal heat pump cabinet. . Energy saving thanks to the internal bypass Heres a list of everything: Normally, when an AC starts, the compressor draws a huge amount of electric current and it keeps doing so every time it starts. At the same time, it also makes the motor produce LESS torque per unit of current, which in this case may end up making it take longer to accelerate, which may make the VD experience worse. By continuously monitoring motor current and voltage, the new module can reduce in-rush current by up to 75% during start-up and detect low supply voltage while the compressor is running, protecting against damage from low voltage or locked rotor.
