1. Product Overview
ATC1500 series Automatic Power Supply Test Systems are designed to efficiently test
power adapters, single output power supplies and battery chargers. There are various
models in the series, ranging from small portable model to full featured rack models.
Since its launch in 2009, ATC1500 series products have been well received by power
supply manufacturers and quality control professionals.
2. Features of the Auto-tester
 Innovative compact design for testing single-output power supplies and battery
chargers up to 150W of output power (patent pending).
 Fastest test time in industry, as low as <1 sec per test item.
 Highly accurate. Most parameter measurements are within 0.1% accuracy.
 Capable of measuring the standby power of a power supply accurately (< 0.3W
range).
 Capable of average efficiency measurement.
 Capable of testing with CC, CV, CR and LED loads.
 I-V curve plotting function for CC/CV power supplies/chargers.
 Capable of measuring inrush current.
 Easy-to-use User Interface software enables user to generate test sequence for
different power supply models quickly.
 Test results and statistical data such as mean, standard deviation, Cpk and
histogram can be generated with the click of a button.
 Test sequence can be saved in a file and recalled later when needed.
 Various configurations to suit different customers.
3. Benefits of the Auto-Tester
 Automatically test electrical parameters of power adaptors, chargers.
Eliminate human error in manual testing.
 Increase test speed and reduce labor cost.
 Automatically record test data and generate statistical data for Statistic Process
Control (SPC).
 Fast, accurate and easy to use.
 Reliable and proven technology.
