The power management reliability dictates the long-term performance of any industrial application.

The new Industrial 4.0 revolution has created demand for more stringent capabilities than ever before. Safety, compliance and reliability of our customers' industrial technology are evolving, and power supplies are at the core of these demands.

Further demands for system personalization, intelligence, mobility and ruggedization are shaping industrial applications of the future. IoT, AI and machine learning provide new opportunities to transform industrial processes and gain efficiencies, while maximizing safety, systems availability and reliability in extreme or harsh environmental conditions.

TDK-Lambda's industrial power supplies are designed to stand up to the extreme temperature, input surge, vibration and shock found in industrial automation, material handling, industrial lasers, robotics, agriculture, oil and gas, mining, outdoor applications and more.

Our technology is designed for superior thermal management, reliability, EMI/EMC specifications and power density, with rugged performance that is typically unavailable in standard power supplies. We offer products with expansive functionality in a range of performance classes that are supported by industry leading warranties.

Hazardous Location Certifications


Power supplies used in an explosive atmosphere may require hazardous location certification. Power supplies provide regulated voltages to drive motors, relays and power-electronic controls. As power supplies produce heat and contain high voltages and/or high currents, they need to be thoroughly tested to ensure sparks and high temperatures will not compromise system safety.

Our Solutions

We have many supplies with a variety of hazardous location certifications. Power supplies with hazardous location certification make system designs easier to certify and ensure safety to the end user.

UL 508 and IEC/EN/UL/CSA 61010


UL508 and IEC/EN/UL/CSA 61010 are the safety standards for industrial control equipment rated 1500V or less. Power supplies are thermally tested to ensure they will operate safely in enclosed cabinets or as stand-alone products. Terminations to the products have to be designed to be field wired, often with bare wire connections.

Our Solutions

Our supplies with UL508 and UL61010-2-201 certifications are UL "listed" rather than "recognized". This allows the product to be used in control cabinets at 100% of their rated load, rather than requiring a 50% derating. In addition to our extensive DIN rail mount and programmable power supplies many of our metal cased industrial products are UL 508 listed.



Sections of MIL-STD-810 cover vibration and shock. How the power supply is mounted can cause mechanical resonance in the system. When the entire system is subjected to shock and vibration, a power supply containing one or two supplies may start to vibrate at amplitudes greater than the system itself.

Our Solutions

Our ruggedized power supplies offer mechanical reinforcement, such as potting for power modules, with adhesive and additional mechanical support for larger components. These products are tested by independent companies to ensure compliance.

Long Life/Superior E-Caps


Electrolytic capacitors are used extensively in power supplies but degrade with time and temperature. With every 10°C reduction, the lifetime of the cap doubles.

Unless care is taken to maximize capacitor life-time, power supplies will no longer meet their published specifications and cause system failures.

For example a capacitor has a stated life of 5,000 hours at 105°C case temperature (operating at maximum ripple current). At 85°C, the life increases to 20,000 hours (5,000 x 2 x 2 = 20,000).

Our Solutions

We measure all the electrolytic capacitors (e-caps) in our power supplies under the operating conditions for the end application. This is essential to estimate the life that can be expected from the power supply.

TDK-Lambda is acutely aware of the impact of capacitor wear-out and the effect it has on start-up, output ripple and AC hold-up times.

We can provide units which have thermocouples already attached and additionally, we can provide all data on e-caps used.
