Is the increasing accessibility of industrial power technology a positive trend for manufacturing efficiency?
TDK-Lambda has released the TPF12500-385 series, a non-isolated three-phase power supply engineered to deliver 12.5 kW of nominal power. This new unit is designed to support distributed power architectures in smaller systems while maintaining high efficiency.
Why it matters
The new design aims to simplify power systems by avoiding the need for liquid cooling. This approach allows for more flexible installation in confined environments where traditional thermal management might be impractical.
The TPF12500-385 series offers 97.5% efficiency and accepts 360-528 VAC inputs at 47-63 Hz. Each 12.7 kg unit features RS-485 monitoring and can be paralleled to provide 25 kW of power.
The players
TDK-Lambda
This is a global manufacturer of power conversion products that serves the industrial, medical, and semiconductor markets.
The details
The system relies on internal fans to manage thermal loads, eliminating the complexity of liquid cooling infrastructure. It incorporates droop-mode current sharing for seamless parallel operation and is fully compliant with MIL-STD-810H and SEMI F47-0706 standards.
Timeline
TDK-Lambda released the TPF45000-385 power supply in 2021.
The TPF12500-385 power supply series was introduced on October 2, 2026.
The Tech Race
This release continues the expansion of the manufacturer's high-power hardware range following the success of the TPF45000-385 power supply series. By scaling down power requirements, the company is positioning itself to capture smaller-footprint industrial applications.
System integrators can now implement air-cooled high-power solutions without the operational costs and maintenance associated with liquid cooling. This flexibility allows for easier deployment in confined or legacy infrastructure environments.
The takeaway
The move toward air-cooled 12.5 kW modules signals a shift in industrial power design toward modularity and simplified installation. Designers can achieve significant space savings by selecting components that eliminate redundant thermal management hardware.
