The top 3 TDK-Lambda AC/DC power supply series
Power supplies are the unsung heroes of modern systems, ensuring stable and efficient energy conversion for sensitive equipment. TDK-Lambda offers a broad portfolio of high-quality, field-proven AC/DC power solutions across various industries.
"The CUS, LS, and DRB series from TDK-Lambda really hit the mark, combining top-tier reliability and efficiency with functionality tailored to specific applications. The CUS series is geared towards high-performance medical and industrial needs, while the LS series serves as a rock-solid, general-purpose power solution. For industrial automation, the DRB series stands out with its compact DIN rail design and an impressively long service life. Together, they offer a flexible, robust range of solutions that can support almost any electronic system," says Pavel Kováč, Product Manager at SOS electronic.
CUS series – open-frame AC/DC converters by TDK-Lambda
We’ve recently added the CUS series to our stock - a range of high-efficiency, open-frame AC/DC power supplies built specifically with medical and industrial equipment in mind.
What really sets these units apart is their impressive power density and the fact that they meet the toughest safety standards out there. With certifications like IEC/EN 60601-1 for medical devices and IEC/EN/UL 62368-1 for IT and comms, they take the headache out of the system approval process and give you peace of mind in critical environments.
If you’re working with enclosed cabinets, the CUS series is a smart, cost-effective choice. The open-frame design isn't just about saving space; it naturally boosts heat convection, which is vital for keeping those sensitive electrolytic capacitors healthy. You can choose from several configurations to fit your build, including PCB-only, aluminium baseplate, or U-channel heatsink versions. |
A standout in the range is the CUS600M family, delivering up to 600 W in an industry-standard 3 x 5-inch footprint. Plus, it gives you the flexibility to use either convection or forced-air cooling, so you can design your system exactly how you need it.
Key features and benefits of the CUS series:
- Wide input voltage range: typically between 85 V and 265 V AC
- Power output: up to 1000 W depending on the model
- Efficiency: 95–96%
- Certified: compliant with the latest safety standards
- Quiet operation
- Compact design: saves space in end-user equipment
- Versatile application
Typical applications:
Diagnostic equipment, dental tools, test and measurement systems, broadcast equipment, and industrial control systems
LS series – metal-enclosed AC/DC converters by TDK-Lambda
The LS series is our go-to recommendation for a cost-effective, robust AC/DC solution in general industrial and commercial settings. These units are the ideal choice when reliability and a long service life simply aren't up for negotiation.
These metal-enclosed AC/DC converters handle a wide input voltage range, making them ready for global use without any extra adjustments. They are also built to be tough, capable of withstanding temporary surges of up to 300 V AC - providing a vital safety net if your power conditions are unstable.
| The real headline of the LS series is the extraordinary reliability. With a Mean Time Between Failures (MTBF) of up to 900 000 hours, it significantly cuts down on maintenance and prevents costly system downtime. |
Features and benefits of the LS series:
- Wide input voltage range: 88 V – 264 V AC
- Output voltage: from 3,3 V to 48 V
- Power: 25 W – 150 W depending on the model
- Surge protection: up to 300 V AC for 5 seconds
- Temperature range: –25 to +70 °C
- 5-year warranty
- Compact design: space-saving for end devices
- General-purpose: ideal for light industry
Typical applications:
Factory automation, industrial machinery, LED systems and instrumentation
DRB series – DIN rail AC/DC converters
The DRB series features compact power supplies specifically designed for DIN rail mounting. It serves as the modern successor to the popular DPP series, which is no longer recommended for use in new projects.
| While straightforward in terms of features, it is a highly reliable, compact, and affordable series of AC/DC DIN rail converters. The series allows for output voltage adjustment within a specific range and boasts an enhanced service life, typically up to 10 years. |
The DRB series models come in two power levels, and all models can handle a peak power of 120% for up to 2 seconds to manage capacitive loads. Additionally, low inrush current prevents nuisance tripping of circuit breakers. For more demanding power requirements or redundant setups, you can easily connect units in parallel.
Features and benefits of the DRB series:
- Output voltage: 12 V, 24 V, 48 V
- Adjustable output range
- Power levels: 120 W and 240 W
- Peak power: 120% for 2 seconds
- Efficiency: 94%
- Service life: 10 years
- Compact footprint: saves valuable DIN rail space
- Remote On/Off
- Terminal options: choice of screw or push-in terminals
- LED status indicator
Typical applications:
PLC systems, automation controllers, security systems, lighting installations, and building management systems. These units are optimised for easy installation and maintenance within standard electrical distribution panels.
The most popular AC/DC converters models are in stock and ready for immediate shipment, while additional TDK-Lambda power supplies can be supplied on request.
