As a result, your air conditioner will be able to start multiple times per hour if needed. Simulation mode When you turn on the air conditioner, the compressor draws a huge amount of electric current. Once the downstream pressure gets to the setpoint, the valve opens fully to allow the full flow of compressed air into the apparatus. 1. For testing I got my 0-300v 20amp 5kw varrac wired up with new cord, plug and switch. This sudden and massive jolt of current can instantly damage your air conditioner or reduce its life significantly. When the PTCR heats up, the resistance inside increases, and it essentially takes itself out of the circuit. All of the compressors in that large building had VFD'S . This means that even if the cylinders have flow controls, which work on controlling backpressure, there is no air in the cylinder to allow the flow control to moderate the speed of the cylinder piston. When you connect the power, the current can be very high (even tens of amperes). If a motor is not start & stopped more then a few times a hour doubt that heat rise due to lack of a heat sink would be a problem. EasyStart Soft Starters - Micro-Air, Inc.
