TEN 40-1210 Application Field and Working Principle

The TEN 40-1210 is a DC-DC converter that is specifically designed for applications with tight energy budgets. This versatile, compact and easy-to install device can efficiently meet various data-processing, system control or communication power requirements. It offers a high performance solution to where efficient power transfer without the need for additional components is necessary.

The TEN 40-1210 features a boosting circuit, which can raise the input voltage to sustain the power needs of the different devices it is connected to. The converter unit also supports intelligent control features enabling it to operate autonomously, as well as support power-saving functions.

The TEN 40-1210 is suited for many different applications such as industrial, medical and telecom, sensing applications. The device has a wide input voltage range from 9-36Vdc and is capable of providing isolated output up to 12W with a single output voltage of 5Vdc. The device also supports other fixed output voltage range from 12Vdc to 24Vdc, making it easy to use for various applications.

Working Principle of the TEN 40-1210

The TEN 40-1210 uses a PWM (Pulse Width Modulation) technology which is based on a DC-DC topology. The converter uses an inductor, a diode and a capacitor to achieve power conversion on the fly. When the input voltage is lower than the desired output voltage, the PWM control circuit will increase the switching frequency and reduce the duty cycle of the load. As the switching frequency and current through the inductor is increased, the voltage across the inductor also increases. The capacitor filters the pulse-width-modulated signal. This PWM process helps to reduce the input current and maintain a stable output voltage.

In order to keep the converter from shutting down due to overcurrent, an over-current protection (OCP) scheme is provided. The over-current protection circuit will detect the current at the output and compare it to the set current limit value. If this current is higher than the limit value, the OCP circuitry will shut down the converter.

The device also offers various output protection features such as short circuit protection (SCP) and reverse polarity protection. The thermal protection (TP) feature ensures that the switching losses do not accumulate and cause unexpected thermal shutdowns. This is achieved by monitoring the temperature of the converter through a temperature sensor.

In summary, the TEN 40-1210 DC-DC converter is a reliable, efficient and cost effective power solution for a wide range of applications. It features a boosting circuit, over-current protection, short circuit protection, thermal protection and reverse polarity protection, making it one of the most versatile DC-DC converters in the market.
