Product Description
The Nemic-Lambda (TDK-Lambda) LWT50H-522 is a triple-output, open-frame AC-to-DC switching power supply rated at 50W. It accepts a universal AC input range of 85–265VAC and delivers three isolated DC outputs: +5V at up to 8A, +12V at up to 1.5A, and –12V at up to 1A. The unit features a low-profile design of approximately 1 inch (26mm) height, convection cooling, and built-in overvoltage/overcurrent protection, making it well-suited for information devices, communications equipment, and FA control systems.
