The HP/Agilent E3632A is a 120 W single-output DC power supply engineered for benchtop and system integration. It delivers dual output ranges—0 to 15 V at 7 A, or 0 to 30 V at 4 A—making it suitable for diverse power delivery requirements. The unit combines low output ripple and noise with excellent line and load regulation, backed by built-in digital measurement and programmable protection circuitry.
