DC-DC converters are power electronic devices for converting a dc voltage to another dc voltage in a limited frequency range. TDL 2-4813 is a family of high-efficiency, bidirectional, offline switched-mode dc/dc converters for electrical equipment control and power demanding applications.

The TDL 2-4813 dc/dc converters provide reliable, regulated power conversion of both ac and dc input sources with a wide input voltage range of 48 to 90V AC, 230 to 410V AC, and 300 to 550V DC. The output voltage is adjustable from 12 to 48V DC, and the output current ranges from 3A to 12A. The peak efficiency of the converters is up to 94%.

TDL 2-4813 dc/dc converters provide high reliability due to its over-voltage, under-voltage, over-temperature, and overload protection features and have a variety of enhanced features such as active power factor correction (PFC), electronic current limiting (ECL), and remote monitoring/ control options.

The working principle of TDL 2-4813 dc/dc converters is based on the use of a high-frequency oscillator to convert an ac input voltage to a low-frequency high voltage dc. The dc voltage is then fed to the primary side of a transformer, where it is rectified and converted into a regulated dc voltage. On the secondary side, the voltage is rectified and filtered to produce a regulated dc output.

The PFC feature ensures that the TDL 2-4813 converters meet the harmonics limits set by international standards by reducing or eliminating the input harmonic current. The ECL enables current limiting by detecting an overload condition and limiting the output current to a safe level. The monitoring/control option allows users to remotely monitor the device’s active parameters (e.g. volts, amps, frequency, temperature) and control the parameters (e.g. voltage, current, frequency) to optimize the operating conditions.

TDL 2-4813 dc/dc converters are ideal for applications such as variable frequency drives, medical equipment, point-of-sale systems, motor controls, industrial automation, LED lighting, and power supplies.

In summary, the TDL 2-4813 dc/dc converters provide high efficient power conversion, PFC, ECL, and remote monitoring/control options, making them a reliable and cost-effective choice for a wide variety of applications.
