The Lambda / TDK / EMI LK351-FM is a 900 W DC power supply for automatic test equipment, laboratory, and industrial applications. It delivers 0–36 V DC at up to 25 A with exceptional line and load regulation of ≤0.01% of full scale (or 0.015% or 1 mV, whichever is greater), ensuring stable output for precision measurement and component testing. The unit accepts 85–265 V AC single-phase input and operates across 47–63 Hz, making it suitable for global installations.
