The device also features remote on/off control, adjustable output voltage, and over-voltage/over-current/short-circuit protections.

The working principle of the PDQ15-Q48-S5-D converter is based on the Pulse Width Modulation (PWM) control method. This method involves regulating a pulse width signal to control the average output voltage of the device. The line and load regulation of the device is accomplished through the use of a feedback system. This type of system is typically employed in a non-isolated converter configuration, where the load is directly connected to the input source.

The PDQ15-Q48-S5-D converter consists of an input rectifier, an internal boost diode, an internal transistor switch, a driving circuit, and an output rectifier. The input rectifier converts the AC voltage from the input source into a DC voltage. The internal boost diode provides the voltage gain to the signal that is necessary to produce the output voltage. The transistor switch is responsible for switching the current on and off to regulate the output voltage. The driving circuit generates the PWM control signal. Finally, the output rectifier converts the PWM signal back to a DC voltage.

In conclusion, the PDQ15-Q48-S5-D DC-DC converter is an efficient and reliable device that can be used in a variety of applications. It features a wide input voltage range, an adjustable output voltage, and it operates at temperatures from -40°C to +85°C. Additionally, the working principle of the device is based on the Pulse Width Modulation (PWM) control method. For these reasons, the PDQ15-Q48-S5-D DC-DC converter is an excellent choice for applications requiring low-medium power and high efficiency.
