HP Agilent 6654A DC Power Supply

The HP Agilent 6654A is a 500 W single-output DC power supply engineered for design, manufacturing, and laboratory testing environments. It delivers 0–60 V DC at 0–9 A (40°C rating) with programmable voltage and current control via GPIB/SCPI commands and analog remote programming. The 6650 series architecture emphasizes fast programming response - output voltage settles within 60 ms - and transient recovery under 100 µs, maximizing test throughput in production and R&D applications.
