The dehumidifier can remove humid moisture and suspended particles through operation, making the air dry and fresh. It is widely used in all aspects of production and life, creating a comfortable, dry and quiet modern living space for users. The following are frequently asked questions (FAQ) about using the dehumidifier in our daily operation and production.

1. Why should the dehumidifier be placed for a period before operation?
2. Where should I place a dehumidifier?
3. Can I open the door and window when the dehumidifier is running?

When a current spike or voltage surge suddenly occurs in an electrical circuit or a communication line due to external interference like lightning, surge protection device (SPD) can conduct the shunt in a very short time, thereby avoiding the damage of the surge to other equipment in the circuit. It is an indispensable device for lightning protection in the electronic equipment. But some people are still wondering why we need it, or whether need it when we have other lightning protection device? The following FAQ will give your answer for "Why you need a surge protection device".

Sometimes one has to (still) use a dedicated net just for servos but that is old. Different fieldbuses and/or servo drive interfaces may support a partial frame; for example, one may only be able to set a control word which might be position or torque command while some may support a full parameter frame or command set which exposes a plethora of servo parameters and variations between the two extremes. Speed is also a consideration i.e. may only be fast enough to do motion control or fast enough to close a servo torque loops and/or fast enough to incorporate feedback devices e.g. force or range sensors (without wiring directly to the servo drive).
