Power Supply JWS50-5/A - Fair Condition

TDK-Lambda JWS50-5/A 5V 50W industrial power supply – High reliability and international compliance

The TDK-Lambda JWS50-5/A is an industrial-grade switching power supply designed to provide a stable output voltage of 5V with a maximum power of 50W. Part of the JWS50/A series, this unit is renowned for its robustness, reliability and compliance with international safety standards such as UL60950-1, CSA C22.2 No.60950, and EN60950-1.

With its wide input voltage range of 85 to 265VAC (or 120 to 330VDC), the JWS50-5/A can be used in a wide variety of electrical environments, making it particularly suitable for industrial applications, embedded systems, test equipment, and non-critical medical devices. Its typical efficiency of 74% ensures optimised energy consumption and reduced heat dissipation, facilitating fanless convection cooling.

The design incorporates overcurrent and overvoltage protection, ensuring the safety of connected equipment. In the event of an overload, the system automatically limits the current and resets without manual intervention. In the event of an overvoltage, the output is disabled and requires manual restart, ensuring effective protection against damage.

The JWS50-5/A is also designed to operate in harsh environmental conditions, with an operating temperature range of -10°C to +55°C and relative humidity of 30 to 90% without condensation. Its mechanical robustness is enhanced by vibration and shock resistance, making it reliable even in industrial environments subject to physical stress.

With compact dimensions of 37 x 85 x 159 mm and a weight of only 400 g, this power supply is easy to integrate into space-constrained systems. It also allows for series operation, providing additional flexibility for multi-voltage configurations.

The JWS50-5/A complies with electromagnetic emission standards such as EN55011/EN55022 Class B, FCC Class B and VCCI-B, ensuring optimal EMC compatibility in sensitive environments.
