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.
