AC/DC converters bridge the gap between alternating current supplies and the rigidly regulated and powerful DC loads used in many applications. TXH 120-112 AC/DC Converters are designed to operate from a single, wide input voltage range of both AC (85-264VAC) or DC (90-370 VDC). This makes them perfectly suited for use in a variety of power supply applications.

They feature a three-phase bridge-controlled rectification stage with two stages of PFC control. The output voltage range is 50-450 VDC, and the output current range is 10A-125A. The converters are highly efficient and require minimal external components. They are also immune to fast transients, and operate without input current overload.

TXH 120-112 AC/DC converters incorporate a unique switch-mode power factor corrector (PFC) and ‘intelligent’ current feedback loop control, which provides optimal regulation and dynamic response for the output. When power is applied, the integrated PFC circuit automatically corrects the input current waveform to ensure correct output voltage and current levels. The output voltage is adjustable from 0 to 0.7 times the input voltage, and the output current can be adjusted from a 5A minimum to 125A maximum.

The high-frequency power circuitry of the TXH 120-112 allows the output voltage waveform to remain flat from low to high load conditions. This ensures excellent dynamic performance, even in the most challenging conditions. Additionally, self-diagnostic circuitry continuously monitors the output to ensure accurate regulation and fault protection. Should it detect a fault or over/under-voltage/current condition, the unit will automatically power down to protect the load from damage or dysfunction.

The TXH 120-112 is designed to reduce energy costs and increase performance in power supply applications. It has high-efficiency power conversion technology, is well-suited for industrial, telecom, and medical environments, and is compliant with UL/CSA/EN/IEC safety regulations, as well as RoHS and ErP directives.

Energy savings can be further enhanced through the use of an optional integrated PFC measurement controller, which continuously monitors input and output parameters and takes corrective actions accordingly. The integrated controller can regulate input power factor according to the required load, which results in increased efficiency and improved energy savings.

In summary, TXH 120-112 AC/DC converters offer a versatile, reliable, and energy-efficient solution for high-power applications. They are built with robust components and feature high-frequency operation for excellent dynamic performance. The unit is protected against overload, overvoltage, undervoltage, and short-circuit conditions, and its compact design makes it easy to install and maintain. It is compliant with safety regulations and is well-suited for industrial, telecom, and medical applications.
