The Anritsu 6653A is a 525 W single-output DC power supply engineered for automated test systems and high-volume manufacturing. GPIB-programmable with SCPI command compatibility, it delivers fast voltage and current programming for efficient device testing. The unit supports analog control of output voltage and current, fan speed modulation for noise reduction, and multi-unit daisy-chaining of up to 16 supplies through a single GPIB address. Integrated protection includes fast crowbar and mode crossover protection to guard against DUT damage.
