Keysight 66000 Series Modular Power System
2 models with full specifications from Keysight Technologies (Agilent HP).
The Keysight Technologies (Agilent HP) 66000 Series is a high-density DC power solution configured specifically for Automated Test Equipment (ATE) and production testing. This modular power system (MPS) is composed of the 66000 Series - 150W Mainframe (commonly matching the 66000A designation) and the 66000 Series - 150W Modules. By housing up to eight individual outputs in a single chassis, the system offers space-saving density. Designed to deliver reliable, programmable power, this system is suited for engineers needing multiple independent DC sources controlled via a central standard interface.

Mainframe Architecture and Control
The 66000 Series - 150W Mainframe forms the basis of the system, supplying up to 1200 W of total power across eight input slots. It operates from a variety of selectable AC nominal inputs including 100 VAC, 120 VAC, 220 VAC, and 240 VAC at frequencies between 47 and 63 Hz, with a maximum input power of 2100 VA.
System control relies on standard GPIB (IEEE-488.2) and Serial Link interfaces. The integrated Serial Link allows the master/slave connection of up to 16 mainframes, enabling a system designer to control as many as 128 distinct outputs from a single GPIB address. For system safety and signal handshake, the mainframe features a Discrete Fault Indicator (DFI) line and a Remote Inhibit (RI) line.
High-Density 150W Modules
The 66000 Series - 150W Modules (spanning models 66101A through 66106A) install directly into the mainframe's empty slots. Each modular channel delivers up to 150 W of DC power. Because these modules lack individual displays or manual physical interfaces, configuration and diagnostics occur directly through the mainframe interface using SCPI commands.
Each module contains built-in measurement and safety features. Designed for forced-air cooling supplied by the mainframe internal fans, the system maintains operating acoustic noise levels below 45 dBA. Individual modules have a physical footprint of 66 mm W × 217 mm H × 460 mm D and weigh 5.5 kg, with a recommended calibration interval of 1 year.
Frequently asked questions
- Can these modules be controlled individually on the front panel?
- By default, the mainframe features status LEDs. Direct local entry and display require the optional 66001A front panel keyboard, which adds a vacuum fluorescent display.
- What is the maximum number of outputs controllable from a single GPIB interface?
- Using the Serial Link interface, up to 16 mainframes can be connected in a master/slave arrangement, allowing control of up to 128 total module outputs from one GPIB address.
- What are the environmental limits for these modules and mainframes?
- Both the 66000 Series mainframe and its 150W modules are specified to operate safely in temperatures ranging from 0 to 55 °C.
