3000VA - 15000VA precision AC power in single,
split or three phase
Product Overview
Now you can test any product that operates from AC power with the most compact, versatile power source in the test industry. The L-Series' small size provides more power per inch than most other AC supplies. Highly efficient, these products dissipate less heat than previous generation systems and allow up to an additional 10 % output power. With a programmable controller, L-Series models provide the most comprehensive set of programmable functions in the industry. Automatic remote calibration and comprehensive self-tests simplify maintainability.
All L Series units are completely self-contained. Control is through an embedded oscillator, factory configured to your specific requirements. Output parameters are controlled via the front panel or the IEEE-488 bus. Bus programming, standard with -P, -PT and HGA controllers, allows programming and measurement function readback compatible with a number of other standards including VXI, MXI and RS232 via recommended translators. To simplify programming, the standard unit supports both Abbreviated Plain English programming and an ATLAS-based control language.
For avionics applications, any 3-phase model can be configured with 26 V and 5 V auxiliary outputs. (AX option)
The L Series is ideal for applications where small size, low heat dissipation and light weight are important. These include DC power supply testing, production test, quality assurance verification, engineering and ATE.

Programmable Functions Allow Simulation of Complex Line Conditions
The broad range of programmable functions available with the L-Series allow you to test for virtually any line occurrence. The -P and -PT programmable controllers are equipped with 16 transient registers that can be programmed from the front panel keypad or the IEEE-488 interface. Here are some capabilities of the L Series programmable controllers:
Set the voltage on each phase individually with 0.1 volt resolution.
Set the frequency with 4 digit resolution.
Set phase angles for phase B and C with respect to phase A with 0.1 degree resolution.
Set a power surge or blackout from 1 mSec to 2 hours duration to simulate power utility generation and distribution problems.
Set the starting point of the sine wave anywhere from 0 to 360 degrees with 0.1 degree programming to test for maximum load in-rush current.
Select sweep of voltage, frequency and/or phase angle to test for catastrophic failure and brown-out conditions.
Program voltage dropouts at any phase angle, either by time or cycle count, to test for correct operation in the vicinity of a heavy intermittent load such as an air conditioner or refrigeration plant.
Select internal or external synchronization signal and measurement strobe function to ensure reliable operation in a complex measurement system that includes an oscilloscope or other recording device
Save custom setups in nonvolatile memory for easy recall (front panel or bus)
Link memory locations for complex setup sequencing that can cover many hours for complex multi-line standard burnin testing.
Included Windows™ Software Eases Transient Programming
All L Series AC sources shipped with a programmable controller (-P, -PT or HGA) include a Windows™ Graphical User Interface (GUI) program. The GUI supports all functions and capabilities of the L Series controller used. The following tasks can easily be performed through this graphical user interface using the IEEE-488 interface (National
Instruments PC IEEE controller required):
Control all output parameters such as voltage, current limit, phase and frequency.
Compile lists of transient programs on disk for quick recall and execution
Measure and record key output parameters such as volt rms, current, peak current, real power,
and power factor.
Run RTCA/ DO160C (requires option - 160) or MIL-STD 704D tests (requires option - 704)
Monitor remote control commands over the bus using the built in command viewer window to quickly learn how to program the L Series yourself.
Drivers for popular programming environments such as LabViewT or LabWindows/CVIT are available as well for custom software development If needed, the front panel can be locked out to prevent operator intervention during test runs.
