Introduction

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

NOTE

The Tester 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.

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
