Why do we need electrical safety test

As an excellent LED lighting, it will use a variety of test standards for different countries and regional markets. So what kind of measurement methods and test standards should we master for a qualified LED lighting?

LED Lamps

According to statistics, in most LED production companies, there will be: AC withstand voltage, (or) DC withstand voltage, insulation resistance, ground resistance, electrical parameters (voltage, current, power, power factor, frequency) … leakage Current test.

Maybe you will feel: “This is everyone known, set the limit parameter to the instrument”, but when you really do it, you will find that you spend a lot of time in setting up instruments and calibration instruments. It’s up, thereby lowing production efficiency. Maybe you will say: “Are these not very easy? The team leader we produted workshops”, it looks very simple, feel that you will do it.

This is a large part because the LED lamps produced by the factory are exported to the world, but the test standard limit is not unified, and it is afraid of exporting the same area, but the lamp itself also points I level lamp and II level light fixtures, but test methods and conditions are not the same. Have you encountered the following situation: Adjust parameters, set limit, and calibration instruments spent nearly 30 minutes (employees waiting next to wait, it will waste more time) suddenly remembered what is wrong, or forgets the upper and lower limits range, the products just tested will also re-detect once.

Since individuals do multiple instruments (time and easy error), there is no instrument to solve all of the above problems, which save artificial improvement of test efficiency? And also test accurate, easy to operate, high test efficiency? LISUN manufacture department and research department have designed and manufactured LS9955/LS9956 Automatic Safety Test System (electrical safety analyzer) combined the following function in one set: Withstand Voltage Test (AC/DC), Insulation Resistance Test (IR), Leakage Current Test (LLC), Grounding Resistance Test (GR) and Power Test.

LS9955_Automatic Safety Test System

The LS9955/LS9956 Automatic Safety Test System is according to GB4706.1, IEC/EN60335-1, UL60335, GB7000,IEC60598, GB4943, IEC60950 and GB9706.1. It is used for luminaries, home application and motor tools safety test in production line or R&D Lab.

Specification:
• Remote control device and can control by software (Optional)
• Display all setting parameters and testing results in the same big LCD menu
• PASS/FAIL limit values can be set. It has alarm sound and indicator light
• Test mode programmable;  50 groups setting available, 8 test steps per group
• Quick discharge. Support 50Hz and 60Hz frequency; Electric safety wall detecting feature
• The LS9955 can do test for Withstand Voltage (AC/DC), Insulation Resistance (IR), Leakage Current (LLC) and Ground Resistance (GR)
• The LS9956 can test for Withstand Voltage (AC/DC), Insulation Resistance (IR), Leakage Current (LLC), Ground Resistance (GR) and Power

What’s the test method of Automatic Electrical Safety System?

Pls. note that the DC high voltage output is a negative voltage, and the ground is a positive. When testing capacitance, there is a charging process when voltage is applied to both ends of the capacitor. At this time, there is a charging current in the test circuit. When the current is greater than the set leakage current value, the withstand voltage tester will alarm to interrupt the test , it cannot be proceed. Therefore, when the safety tester is testing, the voltage should be increased slowly, and the charging current should be less than the set leakage current value until the test voltage is specified, and the test should be performed. It is not possible to use a fixed voltage, reset-start method for testing. In the AC circuit, it is equivalent to the resistance in the DC circuit.
