FAQ when choosing a rainproof power supply

1) The selection of the rainproof power supply  requires the appropriate input voltage, specification model;


2) Select the appropriate output power. In order to better improve the service life of the power supply, models with 30% more power rating can be used.



3) Consider the load characteristics. If the load is a motor, a light bulb or a capacitive load, the current is very large when it is started, and a suitable power supply should be used to prevent the load. If the load is a motor, the voltage reverse flow should be considered during shutdown.



4) In addition, the working temperature of the power supply and whether there is any additional auxiliary cooling equipment need to be considered. The power supply needs to derate the output when the ambient temperature is too high. A plot of the derating curve of ambient temperature versus power.

How to choose the right home elevator

Humanize Humanization is the first thing to look at for home elevators. The purpose of installing elevators in homes and homes is for the convenience of the elderly and users. home lift ，  If the elevator space is too small to fit anything, it is useless. look safe Safety and reliability is of course one of the most important factors in choosing an elevator, so how to choose a safe and reliable home elevator is also very important. see energy saving Energy-saving and environmentally friendly home elevators need to consider noise, whether it is environmentally friendly and pollution-free, how much ceiling, and how much power consumption. The current energy-saving and low-noise elevators are machine room-less elevators. like： Elevator Operation Standard Analysis What are the advantages of traction elevators: What to pay attention to when choosing a home elevator

How to identify the characteristics of inferior aluminum profiles

Unqualified chemical composition The cost of aluminum profiles mixed with a large amount of miscellaneous aluminum and waste aluminum in the product is greatly reduced,  die casting company ，  but it will lead to unqualified chemical composition of architectural aluminum profiles, which will seriously endanger the safety of construction projects. Shorten closing time Inferior aluminum profiles greatly reduce sealing time, loss and cost of chemical reagents, but the corrosion resistance of the profiles is also greatly reduced. thin oxide film The national standard stipulates that the thickness of the oxide film of architectural aluminum profiles shall not be less than 10um (microns). If the thickness is not enough, the surface of the aluminum profile is easy to rust and corrode. In the spot check, some aluminum profiles without production name, factory address, production license and qualification certificate have a thickness of only 2-4um oxide film, and some even have no oxide film.

How to distinguish between silicone straps and rubber straps

The method of distinguishing between silicone and ordinary rubber is more complicated. Infrared spectral analysis can scientifically determine the type of the corresponding substance through the different absorption peak positions on the spectrum. But for consumers,  silicone watch band ，  it can only be discerned by the senses. Generally speaking, silicone products are colorless, odorless, transparent and colorless. Black silica gel and colored silica gel can also be obtained by adding different dyes. But rubber products have more or less flavor. Natural rubber itself has a bit of a protein taste, and rubber processed with sulfur produces a special taste. Some people judge by softness, ordinary rubber or resin materials can achieve the same softness as silicone products through different additives. like： The difference between a silicone strap and a rubber strap  What to do if you are allergic to wearing a silicone strap  What are the advantages of silicone watches?
