The Agilent/Keysight 6553A is a 500 W single-output DC power supply engineered for electronic testing and development. Its linear topology delivers extremely low noise and ripple essential for precision measurement work. The unit operates from 0 to 35 V and 0 to 15 A, with full front-panel and analog programming control for voltage and current. Fast up- and down-programming capability accelerates test cycles while integrated protection—including fast crowbar, CV/CC mode crossover, and over-voltage protection—safeguards load devices.
