Agilent/Keysight 66102A DC Power Supply

The Agilent/Keysight 66102A is a 150 W DC power module engineered for integration into the 66000A Power System Mainframe. This modular supply delivers 0–20 Vdc at 0–7.5 A with programming accuracy of 0.03% + 8 mV (voltage) and 0.03% + 3 mA (current). Its compact form factor enables up to eight outputs in 4U of rack space, making it ideal for automated test equipment and production environments.
