DC-DC converters are devices that are used to convert Direct Current (DC) power from one level to another. The RTS-2412/H-R device is one such DC-DC converter which is specifically designed to convert 24 V DC into 12 V DC.

RTS-2412/H-R is a heavily regulated DC-DC converter, with features such as input voltage range 20-30V DC, output voltage range 12V DC with ±1% accuracy, maximum output current up to 2A, and a total power capacity up to 24W. Additionally, the RTS-2412/H-R has very good dynamic characteristics, with a very short current turning on and off time, as well as a very fast current limiting response. The RTS-2412/H-R is also capable of handling reverse polarity and short circuit protection, with automatic current limiting and short-circuit protection.

The RTS-2412/H-R is most commonly used in applications such as motor control systems, electronic power and instrumentation, and off-board industrial power supply. It can also be used in applications such as powering relay systems, automation building systems, off-board signalling systems, and measuring systems.

The RTS-2412/H-R does not directly convert the input voltage into the output voltage, rather it employs an intermediate step of transforming the input voltage into a frequency-driven alternating current (AC) waveform or “switching frequency”. This frequency-driven waveform is then used to generate the required level of output voltage. This process is known as Pulse Width Modulation (PWM) switching.

This method of transforming an input voltage into the required frequency of AC is based on the555 timer IC (integrated circuit) which is mainly used as a high frequency signal generator. It is connected to two MOSFET switches or transistors, a current limiter, and a switching diode. The 555 timer generates pulse width modulated signal which is used to drive the two MOSFET switches. During the on state, the two MOSFETs conduct current alternately, resulting in the input voltage being converted into AC. This AC is then transformed into the required level of output voltage using a switching diode.

The voltage regulation is accomplished by adjusting the timing of the pulse width, based on the feedback given by the current limiter. The current limiter senses the output voltage of the DC-DC converter and sends the signal to the 555 timer IC. This signal controls the pulse width of the 555 timer and thus regulates the output voltage.

In addition to the voltage regulation procedure, the RTS-2412/H-R also employs a protection mechanism to ensure the safe and reliable operation of the device. The system features a reverse polarity protection and short circuit protection mechanism that will automatically trip off if the input voltage or output current exceeds the rated level. Additionally, the device is designed to withstand high temperature operation, and is protected against over-voltage and over-current conditions.

The RTS-2412/H-R DC-DC convertor is an ideal choice for applications where high accuracy and reliability is required and where high efficiency and long-term operating stability is desired. It can also be used in a wide range of applications including motorcontrol systems, electronic power and instrumentation, and off-board industrial power supply.
