There are various switching power supplies on the market. Many electrical engineers do not choose the most suitable and easy-to-use power supply because they do not understand the differences. This causes different problems in the future, such as customer complaints about products in harsh environments, excessive performance redundancy costs, and power efficiency. Can’t have both, etc…
The following is an example of revealing the high-power semi-gelled switching power supply to show what details a switching power supply hides and how it will affect the selection of switching power supply.
(1) Dust-proof and noise-reduction powerhouse
Different working conditions create different application requirements. This high-power, semi-glued, fanless, ultra-narrow chassis switching power supply has outstanding features. The main problems it solves are dust and noise.
① Suitable for closed environments: excellent heat dissipation design
In the chassis, device heat dissipation becomes a big problem. Conventional switching power supplies have built-in fans to dissipate heat, but this will increase the size. At the same time, if there is serious lint/dust/water vapor, the fan will blow these impurities into the power supply, which may easily cause damage to the power supply.
The fanless design eliminates the need to worry about fan damage, which may cause equipment abnormalities; the glue filling process can be used to accelerate heat dissipation through colloid.
② Suitable for outdoor areas: meets wide voltage input
In remote areas, the voltage of the power grid usually fluctuates greatly, and the input voltage range of the conventional power supply is 90-264VAC/1217-370VDC. 430VDC, no fear of power grid fluctuations.
③ No fear of salt spray and dust: semi-filled glue for high protection
The working environment of equipment is often not good. For example, the power supply of equipment in coastal areas needs to deal with salt spray and water vapor, there is serious metal dust inside the machinery factory, and there are often strong vibrations in the processing and manufacturing process. The semi-glued design can effectively avoid the above situations. The glue filling process can protect the internal components and resist corrosion, while also having the effect of fixing the components and enhancing the earthquake resistance of the power supply.
In addition, the exterior of the product is anodized, surface sandblasted, matte tin plated on the body, and blue zinc plated on the screws to further improve the anti-corrosion protection capabilities.
④ Suitable for small spaces: the power supply is ultra-narrow and compact
Compared with mainstream switching power supplies of the same power, this series is ultra-narrow and thin, which helps reduce installation space. At the same time, this product series not only supports the conventional bottom surface installation method, but also supports the side installation method of the product standing on its side, giving users more flexible space for device layout.
(2) Strong transient overcurrent capability
Motor-type loads are very common, requiring high power to start at the moment of startup, and only requiring smaller power to maintain operation after steady state. Many power supplies enter over-power protection during the startup stage due to excessive output power, causing the equipment to start abnormally. Jinshengyang 1000W semi-filled power supply supports >110% Io, constant current protection, the constant current limit turns off the output voltage after a delay of 3 seconds, and recovers after restarting.
(3) Strong application of constant current mode
The semi-filled fanless ultra-narrow chassis switching power supply supports output voltage adjustment, adjustable output current, automatic load reduction in PC mode and other auxiliary functions. The adjustable output current can be adjusted to 20%-110% of the rated current through external voltage.
① Constant current dimming, analog dimming method
The principle of constant current power supply dimming is not achieved by adjusting the output voltage, but by adjusting the output current, because the brightness of the LED lamp is proportional to its current. The analog dimming method directly adjusts the output current of the constant current source to realize dimming of LED lights. The analog dimming method can obtain a very stable brightness adjustment curve.
② PC mode automatically downloads
When users perform charging management, the ambient temperature will often rise during the charging process. In the past, the over-temperature protection mechanism of power supplies was to shut down the output and automatically restore the output state after the temperature dropped.
This product adds an over-temperature automatic load reduction function under the PC function, which can effectively avoid component damage caused by the temperature rising too quickly and not being able to turn off the power in time. It also provides a smaller charging current to ensure charging stability when the temperature is slightly higher.
(4) Summary
As the development of industrial manufacturing becomes more and more refined and complex, how to match the power supply to the equipment in a timely manner and truly maximize the effectiveness of the power supply requires us to jointly grasp and prescribe the right medicine to make the power supply selection more accurate. As a domestic technology-leading industrial power supply company, Jinshengyang will continue to provide users with worry-free industrial power supplies.
