Automatic Electrical Safety Tester

The 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.

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. […more…]
