Its industry-leading design provides high power conversion efficiency and reliable operation. It is also designed to meet a range of safety requirements, including EIA-222-F, IEC-61010, and RoHS compliance.

The SRDB-20E15HR is a highly efficient DC-DC converter that can handle input voltages ranging from 6V to 75V. It has a maximum continuous output power of 20W and can deliver up to 15A of output current. It is designed to operate over a wide temperature range, from -40°C to +80°C, and is rated for 50000 hours of use at full load.

The SRDB-20E15HR features a number of built-in features, such as over-voltage and short-circuit protection, which helps ensure the safety of the converter in a number of applications. It also features an integrated on-off delay logic circuit, which helps ensure that the output is correctly connected to the load without disruption. Additionally, the SRDB-20E15HR features low ripple and low noise, making it suitable for use in a variety of applications.

Working Principle

The SRDB-20E15HR operates on the principle of pulse width modulation (PWM). In this method, the power switch is turned on and off at a high frequency, producing a series of pulses. By changing the width of the pulses and adjusting the duty cycle, the output voltage is regulated. This method allows for efficient power conversion and is reliable, making the SRDB-20E15HR suitable for many applications.

In the SRDB-20E15HR, the input voltage is first converted into a high-frequency PWM signal using an integrated pulse width modulation (PWM) controller. This signal is then fed to an internal power switch, which turns on and off at a very fast rate. This creates a high-frequency square wave signal which is then fed to an output transformer to provide power conversion. The output from the transformer is fed to an output diode, which rectifies the signal and produces the desired output voltage.

The SRDB-20E15HR features a number of advanced features, such as overcurrent protection, over-temperature protection, and short-circuit protection, which provide reliable operation. Additionally, it has a built-in soft start feature, which helps the converter to start smoothly and prevent sudden surges of current.

The SRDB-20E15HR is a highly efficient and reliable power converter designed for a variety of applications. It operates on the principle of pulse width modulation and is pre-programmed with a number of safety features, making it suitable for use in many applications.
