Palo Alto, Calif.Expanding its line of modular power sources, Agilent Technologies is rolling out four new ultra-fast modules and two mainframes that extend to 1200-W. With these products, the company claims it's now the industry leader in the number of outputs and amount of power that can be packed into a 1U-sized (1-EIA rack unit) rack-mountable system.
These products represent a series of enhancements to Agilent's existing N6700 low-profile MPS (modular power system). The N6700 gives you a way to trade off performance, power, and price to match your test needs. The two new mainframes, offering 600-W and 1.2-kW capability, join the currently available 400-W mainframe. In automated applications, these modules respond to commands in less than a millisecond.
All mainframes accommodate one to four modules in a system-ready 1U package size. Four new 300-W basic programmable power supply modules have been added to the N6700 line to extend its range of coverage. The four new 300-W modules, available from 20-V at 15-A, to 100-V at 3-A, are basic DC power supplies that pack maximum power in a module that occupies only one slot in a mainframe.
The four new modules, together with the 16 modules already being offered, comprise a family ranging in power from 50-W to 300-W, at three different performance levels (basic, high-performance, and precision).
As a test system integrator, you can mix-and-match any of these 20 modules in any of the three MPS mainframes to create a DC power system of one to four outputs totaling 400-W, 600-W, or 1200-W of DC power. Pricing starts at $1000/output.
The N6700 line now has new power management features, too. These permit you to allocate mainframe power to the outputs where it's needed. Agilent claims this feature is unique, and provides safety from unexpected and dangerous shutdowns that can occur with power systems without power management when operated in a similar way.
When the sum of the module power is greater than the power of the mainframe itself, firmware provides power management.
The 1.2-kW MPS mainframe automatically senses power available from the AC line and scales back the available output power accordingly. This feature permits this high-power mainframe to be plugged into any standard outlet.
This is convenient for initial bench checkout of the MPS system, and it's also convenient for test development, which is typically done on the bench when a DUT (device under test) isn't yet driven to full power.
Polarity Reversal Relays
Agilent has also added polarity reversal relays as an option to its 50W, 100W, and new 300W basic DC modules. These relays are integrated inside the module, saving rack space and simplifying system wiring.
With a single command, you can switch an output from a positive voltage to a negative voltagewithout changing wiring.
This capability is useful for reverse voltage breakdown testing, or for testing to ensure that DUT designs can withstand reversed bias voltages, such as installing batteries backward into a portable device.
The N6700 modular power system also offers processing speeds the company says is up to ten to 50 times faster than other programmable power supplies. Other features include built-in digital multimeters. The N6700 MPS is also an Agilent system-ready test instrument designed to comply with LXI (LAN Extensions for Instrumentation) Class C.
As LXI devices, these power sources provide USB 2.0 (Universal Serial B), 10/100 Base-T Ethernet, and IEEE-488/GPIB (General Purpose Interface Bus) interfaces as standard features. These hooks support connectivity to a PC, or to a network for access across an engineering workgroup.
N6700 sources can also be remotely operated from any browser, by connecting to built-in Web pages. This supports control and monitoring of power supply operations remotely, and in an operating-system independent manner.
What's more, N6700 MPSs are part of Agilent Open. It ensures industry-standards-based open connectivity in hardware and software.
Agilent Open simplifies the process of connecting and programming test systems. Agilent Open amalgamates a range of system-ready instruments, open industry software, PC-standard I/O, and global support to accelerate test system development. Click here for more information.
Pricing And Availability
The four new N6700 MPS modules and two new system mainframes will begin shipping in January 2006. The new 300-W basic DC power modules are the N6773A (20-V, 15-A, 300-W); the N6774A (35-V, 9-A, 300-W); the N6775A (60-V, 5-A, 300-W); and the N6776A (100-V, 3-A, 300-W).
Each 300-W power module is priced at $1250.
The N6701A 600-W low-profile MPS mainframe is priced at $2500, and the N6702A 1200-W low-profile MPS mainframe is priced at $3,300.
