E363X: Power to the Bench

Agilent E3631A - E3634A powersupplies are designed for benchautomation in R&D design andQA verification. Even at valueprices, these power suppliesdeliver great features and power.Their low noise and excellentregulation are essential for R&Dengineers who need to evaluateassemblies or applications, andfor test engineers who need todevelop repair strategies forproduction.

Hybrid regulation techniquescreate a denser, lighter packageand a smaller footprint—keyconsiderations when benchspace is at a premium. Front-panel output connectionsenable ease-of-use, while GPIBand RS-232 interfaces make fora versatile power source.

Key Features

• Power up to 200 watts andvoltage ranges up to 50 volts

• Low noise and excellentregulation

• Overvoltage and overcurrentprotection (except E3631A)

• Built-in GPIB and RS-232interfaces

• Dual-range outputs in theE3632A, E3633A, and E3634Afor great coverage of voltageand current for variousapplications

• Triple output on the E3631Aallows for flexibility in mixed-signal applications (such asproviding analog and digitalbias power) and for trackingfeature ± 25V outputs

• Front and rear output onE3633A and E3634A

• 3-year warranty

Typical Applications

• General Purpose Bench Testingeither in R&D or in Production

E364X: Basic System Power

The Agilent E3640A - E3649Apower supplies fill the gap betweenmanual bench power suppliesand high performance systemsupplies, offering unmatchedperformance and functionalityat a great price. They’re designedfor moderate-speed test whereautomation is important andthroughput is not critical. Thesesingle- and dual-output, dual-range power supplies are idealfor contract manufacturers andOEMs who need to perform basicelectronic functional tests on avariety of products quickly andeconomically.

All models support GPIB and RS-232 for quick connectivity.SCPI (Standard Commands forProgrammable Instruments)keeps programming fast andsimple. Less than 90 ms outputsettling time keeps throughputhigh without the need for a downprogrammer. Up to five store/recallstates help minimize program-ming time while acceleratingtest. Remote sensing capabilityensures output stability withlonger leads.

Key Features

• Power up to 100 wattsand 60 volts

• Low output noise andexcellent regulation

• Overvoltage and overcurrentprotection

• Front binding posts andrear output terminals forconfiguration flexibility

• Front-panel calibration—unitdoes not need to be removedfrom the rack

• Built-in GPIB and RS-232interfaces

• Simple set-up for easyprogramming

• 3-year warranty

6600: High PerformanceSystem Solutions

Do you need a power supplywith excellent performance andbuilt-in measurement capability?Agilent 6600 Series systemsare ideal for production testapplications where throughputis critical and rack space is at apremium. These one-box solutionsreduce integration time andincrease system reliability, andoffer a variety of features toreduce test costs, increase testspeed, and lower the cost ofintegration and ownership.

Compared to the “E” series,output transitions are over tentimes faster, measurement timesare up to five times faster, andprogram response and commandprocessing times are accelerated.The built-in DMM allows for moreaccurate measure-ment capability.Throughput is significantlyenhanced via the active downprogrammer that can quicklyremove any energy from the unitunder test when the output isprogrammed to zero. Extendedremote sensing capabilitycompensates for voltage dropsin load leads of up to 50 percentof the rated output voltage,eliminating troublesome sourcingand measurement inaccuraciesdue to resistance in the loadwiring.

Key Features

• Up to 200W and 120V• Excellent regulation and

low output noise • Overvoltage and overcurrent

protection • Built-in GPIB and RS-232

(664XA - GPIB only)• Discrete Fault Interrupt and

Remote Inhibit (DFI/RI) forfast remote power disablement

• Analog programming capabilitysimulates a true power sourceand serial link to control up to16 supplies from one address(664XA only)

• 3-year warranty

Typical Applications

• Production Testing• Electronic Sub-assembly Test• Battery Test• Battery Charging
