Overview
The LZS-250-2 is a regulated, single-output industrial power supply manufactured by TDK Lambda. This enclosed AC-DC converter accepts dual input voltage ranges (85–132 VAC and 170–265 VAC) and delivers stable 12V DC output, making it suitable for instrumentation, test equipment, and industrial control applications that require reliable, regulated power. Although discontinued by the manufacturer, fully functional used units remain in service across maintenance and retrofit projects.
