Traco Power Adds 1000 W Series To Metal-Enclosed Power Supplies

When designing power systems for industrial environments, engineers often face a fundamental decision. The decision between opting for the structural convenience of DIN-rail mounted supplies or choosing an open-frame power supply that prioritizes thermal performance and mechanical adaptability. While DIN-rail formats simplify installation, they can introduce limitations, especially in thermally demanding, space-constrained, or cost-sensitive applications. Open-frame units provide better access to airflow and allow tighter integration with custom enclosures and layouts.

That’s where the new TXN 1000 series comes in. Traco Power has begun expanding its established TXN line of metal-enclosed AC/DC power supplies with new 1000 W models.

TXN 1000 W Series

Traco Power’s new TXN 1000 W series is housed in a low-profile, metal-enclosed chassis. The units deliver regulated DC output in 12, 15, 24, 36, or 48 V with universal AC input ranging from 90 to 264 VAC. Despite its slim profile, the TXN 1000 incorporates active power factor correction (PFC >0.9), remote control, load share functionality, and a power good signal, making it capable of supporting redundancy and scalability in distributed systems.

At the heart of the TXN 1000 is a focus on efficient energy conversion and operational resilience. The series achieves up to 92% efficiency, reducing waste heat and minimizing the need for excessive thermal management. The internal EMC filter meets EN 55032 class B standards, and the reinforced 3000 VAC I/O isolation provides an extra layer of protection in electrically noisy environments. These features make the TXN 1000 especially well-suited for applications such as motor drives, robotics, test systems, and high-density control panels, where both reliability and EMI suppression are non-negotiable.

Thermal capability is another standout. These power supplies are rated to operate in ambient temperatures from –30 °C to 70 °C without derating at moderate loads. This opens the door for outdoor installations and sealed enclosures where active cooling isn’t always an option. This also provides engineers with the flexibility to design systems in remote, harsh, or semi-passive environments.

From Multistep to Single-Sweep

Beyond core specifications, a critical advancement in the TXN 1000 W series is the ability to manage high power ranges in a single sweep. Previous generations of industrial power supplies often required staggered configurations or step-based filtering to maintain regulation across broad voltage demands. The TXN 1000 W’s full-range voltage support means engineers can design systems to scale across multiple SKUs (up to 1000 W) without reworking the form factor or introducing extra stages of conversion. This reduces design time, simplifies the bill of materials, and trims weight, especially in mobile or modular platforms.

Built-In Compliance

Power supply certification often becomes a bottleneck in product development, particularly when global deployments demand adherence to regional safety and EMC standards. The TXN 1000 W series mitigates these issues with built-in compliance to IEC/EN/UL 62368-1, European EMC directives, and Low Voltage Directive (LVD) requirements. This is particularly important for OEMs looking to shorten regulatory approval cycles without compromising safety or performance.

Even small additions, like screw terminal block connections and matching 75 cm accessory cables, underscore the design’s focus on real-world integration. When paired with the existing TXN accessory ecosystem, the new 1000 W series provides a near plug-and-play path for upgrading older 200–500 W units without redesigning housing or airflow strategies.

A Power Supply Solution

DIN-rail units may dominate control cabinets, but when power density, thermal tolerance, and mechanical flexibility are a priority, open-frame options like the TXN 1000 earn their place. The series blends broad input compatibility, built-in protections, and standards adherence with the kind of footprint engineers need when every cubic inch and every degree of heat counts.

When reliability, heat resilience, and compliance converge, the TXN 1000 series offers engineers a low-profile solution that delivers full-range power output without adding mechanical constraints.
