Lambda / TDK / EMI GENH 8-90

The TDK-Lambda GENH 8-90 is a 720 W programmable DC power supply in 1U form factor, supporting both rack-mount and benchtop deployment. It delivers 0–8 Vdc at up to 90 A with CV/CC autoranging, low ripple noise (0.008 Vrms), and active power factor correction. Wide AC input (85–265 VAC, 47–63 Hz) and communication interfaces including RS-232, RS-485, and optional LAN/USB/GPIB enable integration into automated test and OEM systems. Master/slave configuration supports parallel operation of up to four units with active current sharing.
