ATSI LST-650 NEMA Load Switch Tester
The LST-650 NEMA Load Switch Tester (Tester) is an automated tester designed to test Load Switches used in traffic signal installations conforming with NEMA Specifications.
The Tester performs a quick functional test of the Load Switch under simulated normal conditions. The following parameters are tested:
- DC input turn-on and turn-off voltage
- DC input maximum turn-on current
- AC output turn-on and turn-off voltage
- AC output leakage current
- AC output turn-on and turn-off time
The Tester connects to a Windows based computer with a USB connection. The LST-650 Test Manager software controls the Tester and allows the users to run manual or automated tests.
NOTE: The LST 650 performs functional testing. It does not test to the limits of the NEMA standard. The AC loads are approximately 240W and 12W depending on line voltage fluctuations.
