The PV75W14-15SW is a type of switching power supply with high-efficiency and wide input voltage range. It provides excellent noise immunity and wide temperature operation. The power supply is mainly used in a variety of industrial fields such as voltage control, control systems, LED systems, communication systems, and automation systems.

The working principle of the PV75W14-15SW is based on the pulse-width modulation (PWM) technique. It employs two power transistors which work as switches. The power is converted in two stages: firstly, the high voltage direct current (HV DC) is converted into high voltage alternating current (HV AC) using a transformer; secondly, the HV AC is converted into low voltage alternating current (LV AC) which is appropriate for the user system. The two stages are controlled by the controller IC which controls the width of the pulses known as the pulse-width modulation technique.

The PV75W14-15SW is designed with a temperature limit feature. If the temperature exceeds a preset limit, the power supply will shut off and will not start until the temperature falls below the preset limit. This feature helps to protect the ICs from damages due to over-temperature. In addition, the power supply also features a current limit function. When the current output of the power supply exceeds a preset limit, the power supply will shut off and needs to be reset in order to work again.

The PV75W14-15SW is usually used in industrial applications such as voltage control, control systems, LED systems, communication systems, and automation systems. It can provide high efficiency and wide input voltage range, and can work well under wide temperature ranges. Apart from that, it also features temperature limit and current limit function, which make it very suitable for regulating power in industrial applications.
