AC Power Testing
Pacific Power Source has incorporated Test Manager into version 1.3 of its UPC Studio Software, a tool for gaining control of universal programmable controller (UPC)-equipped ac power sources. With Test Manager, the user can automate instrument compliance testing and certification, and obtain preconfigured test sequences and test plans from Pacific Power Source. Test Manager helps the user quickly create and run test sequences and test plans. Test sequences consist of one or more output sequences designed to execute a series of automated tasks that control and monitor the ac power source and other instruments. Test results are then stored in user-defined test reports. Test plans manage and simplify complex tasks by allowing the user to link together a series of test sequences into a single test.
UPC Studio delivers a complete graphical interface for the ac power source. UPC Studio including UPC Control and UPC Manager with Output Sequence Browser is free to customers with registration. Test Manager is priced at $1750, with factory-written test sequences starting at $500.

Automated Test System
Intepro Systems' I-9500LXI is an LXI-based power-supply test system that packs all the features commercial users need into one single-bay cabinet. The automated test system addresses the growing market for ac-dc and dc-dc power converters under 1000 W. The tester comes standard with a six-digit multimeter, four-channel digital oscilloscope, five test loads, an 850-Vac power source and Intepro's PowerStar 5 software, which makes design verification, production testing and repair of whole families of power supplies easy.
Built around Intepro's new LXI controller, the system supports both legacy test instruments that communicate using RS-232C, IEEE-488.2 and the company's own Micro1000 and CAN communication buses, while providing a migration path to future LXI instruments. The base system has a single 300-W load and four 75-W loads, an 18-input by 4-output differential multiplexer, 16 digital inputs and 16 outputs, 48 relay drivers and 10 5-A power relays. Five open slots provide space for growth. The architecture also can accommodate the user's choice of 850-Vac, 1250-Vac or 1500-W dc power sources. The I-9500LXI is priced starting at $53,325.
