The LS9955/LS9956 Automatic Safety Test System (electrical safety analyzer) combines the following functions: Withstand Voltage Test (AC / DC), Insulation Resistance Test (IR), Leakage Current Test (LLC), Grounding Resistance Test (GR) and Power Test (LS9956 includes Power Test, LS9955 does not include Power Test). The equipment is mainly used for lighting fixtures, household appliances and motor tools safety test on the production line or in the R&D laboratory.

Standard:
IEC/EN 60335-1:2023/GB 4706.1-2024 “Household and similar electrical appliances – Safety – Part 1: General requirements”
UL 60335:2022 “Standard for Safety of Household and Similar Appliances, Part 1: General Requirements”
IEC 60598:2024/GB 7000-2023 “Luminaires – Part 1: General requirements and tests”
IEC 60950:2020 “Information technology equipment Safety –Part 1: General requirements “
IEC 62368-1:2023/GB 4943-2022 “Audio/video, information and communication technology equipment – Part 1: Safety requirements”
IEC 60601-1 3.1:2012/ GB 9706.1-2020 “Medical Electrical Equipment – Part 1: General Requirements For Basic Safety And Essential Performance”

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

P.S. The LS9955/LS9956 of Leakage Current Test (LLC) needs to work with LISUN ITEU-SP1KS or ITUS-SP1KS Isolation Transformer (The Output is 1.06times of the input). The LS9955/LS9956 of Leakage Current Test (LLC) and Power Test need to work with LISUN LSP-1KVARC or LSP-1KVAS AC Power Supply.
