DC to DC converters are useful in a variety of applications and have many advantages over other types of power supply solutions. The RE-1209S/P is a high-performance isolated DC to DC converter module designed specifically for use in batteries, solar, and other DC powered systems. This series is designed with a wide range of input voltages and regulated outputs, making it suited to industrial applications as well as consumer, aerospace, and automotive applications.

The RE-1209S/P has a highly efficient design which ensures low heat dissipation and is encapsulated in an ultra-compact size of 30mm x 23mm x 12.7mm with a total weight of only 11g. This series provides three different input voltage ranges of 7.5V-36V, 15V-60V and 21V-72V, and comes with a variety of regulated output voltages of 3.3V, 5V, 12V, 15V, and 24V. Unlike linear regulators, the RE-1209S/P is an isolated converter and offers long-term stability, with negligible variation in its output over long periods of time.

The Working Principle of the RE-1209S/P

The RE-1209S/P module is a high-efficiency, low-noise isolated DC to DC converter. It works on the principle of energizing a transformer core with a high frequency field. The primary side of the transformer is powered by the incoming DC voltage from the power source, and the secondary side of the transformer produces the regulated output voltage. A high frequency switching regulator is used to control the frequency of the transformer so as to maintain the desired output voltage.

The module works by using pulse width modulation (PWM) control. The PWM signal is generated using a microcontroller. The duty cycle (or width) of the PWM signal describes the amount of time that the switch is open vs. closed. Changing the duty cycle of the PWM signal can be used to control the output voltage of the RE-1209S/P. On the primary side of the transformer, the PWM signal is used to turn the power switch on and off. When the power switch is on, current is flowing and the transformer is energized. By varying the duty cycle, the amount of current flowing through the primary of the transformer and the output voltage can be controlled.

Another important aspect of the RE-1209S/P module is the use of an emitter follower transistor as the power switch. The emitter of this transistor is connected to one of the primary windings of the transformer, and the base is connected to the other primary winding. By changing the voltage at the base, the amount of current flowing through the transistor can be controlled. This allows the module to be switched on and off very quickly and with very low energy losses. By varying the duty cycle of the PWM signal, the amount of current flowing through the power switch can be accurately controlled and the output voltage of the RE-1209S/P can be precisely maintained.

The RE-1209S/P module is a high efficiency, low noise, isolated DC to DC converter. It offers several advantages over linear regulators, including low power losses, a very small size, and long-term stability. The RE-1209S/P is designed with wide range input and regulated output voltages, making it suitable for a variety of industrial, consumer, aerospace, and automotive applications.
