EWS150-5 Power Supply - Fair Condition

TDK-Lambda EWS150-5: 150W 5V industrial power supply – High reliability and energy efficiency

The TDK-Lambda EWS150-5 is a high-performance industrial power supply designed to meet the rigorous requirements of modern electronic applications. With an output power of 150 W and a nominal voltage of 5 V, this model is ideal for embedded systems, test equipment, industrial automation and communication devices.

Featuring a wide input voltage range (85–132 VAC / 170–265 VAC or 230–330 VDC), the EWS150-5 automatically adapts to different power sources, ensuring maximum flexibility in international environments. Its 78% efficiency ensures optimised energy consumption, reducing heat loss and improving component durability.

Line and load regulation is precise, with minimal variations even in the event of input or load fluctuations. The product incorporates overcurrent (125%) and overvoltage (115–135%) protection, ensuring the safety of connected equipment. If the overvoltage protection is triggered, manual reset is required, reinforcing user control.

Natural convection cooling eliminates the need for fans, reducing noise and the risk of mechanical failure. The robust metal enclosure, compliant with UL1950, CSA950 and EN60950 standards, ensures reliable electrical insulation and resistance to shock and vibration (up to 20G).

The tele-sense function compensates for voltage losses in the output cables, ensuring accurate power delivery to the load point. The EWS150-5 can also be used in series operation, expanding the possibilities for integration into complex systems.

With compact dimensions of 65 x 97 x 200 mm and a weight of 1 kg, it fits easily into electrical cabinets or industrial chassis. Its compliance with electromagnetic noise standards (FCC Class A, VCCI Class A) makes it an ideal choice for sensitive environments.

The TDK-Lambda EWS150-5 combines robustness, efficiency and safety, offering a reliable solution for demanding professionals.
