Switching power supply units or for short - pulse power supplies are a new generation power sources that combine very high efficiency coefficient, compact size and light weight . Switched-mode power supplies( SMPS or a switcher) belong to the series of power supplies which are able to stand up and stabilize the voltage needed to power an appliance or device. In addition, they stand up and correct the current momentum and clear any interference in it. Among the technicians, they are known as key stabilizers which main principle is to maintain the output voltagevalue at a constant level.
Switching mode power supply units convert the low-frequency current from the power supply network (50/60Hz) into a high frequency one ( 50 kHz), which provides a much higher power . This feature is combined with small and compact dimensions, and with far less weight than standard power transformer .
The main advantage of switching power supplies is their high efficiencycoefficient,which can easily reach up to 93% in most of the modern models. This leads to a reduction of the losses especially by reducing the emiited temperature and the heating. Less precised switching-mode power supplies (SMPS) produce heat and are additonally equipped with a fan to provide the necessary cooling.One of their disadvantage is that they emit high-frequency broadcast signals, which can lead to disturbances in the IT/ computer systems and more precise instruments and devices. Therefore, the impulse units have a metal enclosure, which absorbs the majority of these radiations.
According to the application sphere, there are waterproof and non-waterproof switching power supplies. The waterproof power supplies can be used to power LEDs, LED tubes and LED strip lights. They also have a waterproof housing and a protection degree up to IP65, making them suitable for outdoor installation.
