A DIN rail power supply unit refers to a switched-mode device that converts input voltage that is unstabilised into a stable/regulated output voltage. Unlike transformers that control power supplies linearly, switched-mode equipment is known for reduced weight and enhanced energy efficiency coupled with compact designs. Because of these advantages, DIN rail power supplies are used in multiple applications, including the automotive industry, industrial automation, wind power, and logistics. A power supply unit like this derives its name from the fact that it is attached to a mounting rail referred to as carrier rail or top-hat rail. Here are some of the basic industrial automation facts about the IDEC Distributor DIN rail power.
The Case for DIN Rail Power Supplies -- Commercial power has a very high voltage that is likely to damage the electronic components used in industrial automation. Therefore, such applications require devices that can power down and regulate the high voltage into a direct current (DC) that can support delicate electronic components. In this sense, a DIN rail power supply unit, which is efficient, light and compact, is essential. The high efficiency of this system is achieved through sophisticated components and switch designs that reduce power losses while generating less heat. Therefore, you might not need to cool the system, which can reduce operating costs in terms of energy savings.
Temperature -- Before investing in a DIN rail power supply, you should find out a few things about the specific make and model. One critical aspect to know is the ability of the equipment to withstand tough environmental conditions, including temperature. Since most DIN rail power supplies are used in industrial applications, they should perform at a temperature range of 25°C to +60°C without operating below the rated maximum capacity (derating). Other DIN units can withstand temperatures above 70°C, but the catch is that you have to deal with derating. Therefore, you are advised to check the temperature ratings of the device you plan to buy and compare that to the ambient temperatures of the place you intend to install the DIN rail power supplies.
Beware of Overcurrent -- A common issue with most portable power supply units is overvoltage, which manifests as momentary spikes on the output side of the electronic equipment. The danger with overcurrent is that the power supply device can damage a chip that stores vital information. Usually, overcurrent happens when the DIN rail power supplies draw more power than rated. Overcurrent protection such as fuses, thermistors and transient voltage diode help the system to shut down in case of overvoltage.
