Traco Power Launches AC-DC Power Supply Series for Industrial Applications

From manufacturing facilities to telecommunications networks, the demand for high-performance, compact power supplies continues to grow as industries embrace automation, digitalization, and increased connectivity. Today’s power supplies must meet strict requirements for energy efficiency, electrical noise reduction, and safety, especially as applications become more complex and power densities rise.  

Traco Power has introduced its latest TXN AC/DC power supply series​. The series provides the desirable features of modern power supplies for industrial applications.

Modern Power Supply Challenges

A notable trend in power supply design has been a continual increase in power density or a simultaneous decrease in form factor while maintaining or increasing power output. However, with increasing power density and reduced form factor come several challenges, including reducing the electrical noise output and protecting against its effects. 

The rapid and non-linear switching of electrical currents, which is standard in switching mode power supplies (SMPS), generates electromagnetic interference (EMI). In these converters, power conversion occurs at high frequencies, ranging from several thousand to over a million times per second, resulting in EMI generation. Faster-switching frequencies are a fundamental enabler of reduced area, but faster frequencies result in greater EMI production. Therefore, the designer’s significant challenge is striking the correct balance between the two.  

Meanwhile, power supplies face unique challenges in industrial settings due to harsh environments, surrounding EMI, and safety concerns. Therefore, strong insulation is needed to protect the power supply and connected equipment from potentially dangerous voltage spikes and electrical faults. 

An insulation barrier prevents current leakage throughout the device and ensures the safety of operators and sensitive electronic equipment. Improper insulation can cause high or low-voltage currents to take unintended paths, potentially resulting in electrical fires or dangerous shocks. All forms of electrical insulation must also endure high temperatures without deteriorating or becoming conductive.

Traco Power TXN Series

Traco Power’s TXN series of aluminum metal-enclosed AC/DC power supplies offer several noteworthy specifications, including universal input (90-264 VAC), high efficiency (up to 86%), operating temperature range of -40°C to +70°C, and reinforced I/O isolation of 3000 VAC. Available in 50 W, 75 W, and 100 W variants, these units incorporate an internal EN 55032 class B filter, comply with EN 61000-3-2 standards, and have achieved IEC/EN/UL 62368-1 safety approvals.

Other notable specifications include low no-load power consumption (1 W max) and adjustable output voltages (±8-10%) with an accuracy of (±2%). With a three-year warranty and compact dimensions, these power supplies are best suited for industrial environments. 

Toward Emerging Technologies

As industries advance toward greater automation and connectivity, the demand for efficient, resilient, cost-effective power solutions will only intensify. Power supplies that balance cost, energy efficiency, safety, and durability will be key to supporting emerging technologies. The launch of the TXN series could address these current challenges and set a foundation for accommodating future requirements in harsh industrial environments.
