IEC 60669-1:2017 Clause 19.3 Test for Switches Intended for Self-ballasted Loads

The SBLL-3P20A is used to test the load breaking capacity of self-ballasted lamp switches. It assesses whether the switch exhibits abnormalities such as continuous arcing, contact welding, prolonged closure or opening when controlling LED circuits, and verifies its ability to withstand electrical and thermal stress without excessive damage or other harmful effects. The equipment has a built-in voltage regulator, eliminating the need for an external voltage regulator to meet the required testing voltage. It features a digital display for intuitively showing input voltage and output power, and a pointer-type ammeter for easy observation of current surges. It supports multi-station synchronous testing, has a built-in closing control device, and includes a metering mode and dedicated ports for convenient equipment calibration, metering verification, and related parameter calibration. It also features long-term interruption/long-term continuity protection, with adjustable protection time. Triggering the protection will stop the machine and issue an alarm. It can be used with corresponding plugs, sockets, and switch life testing machines to meet the requirements of standard switch load testing.

Standards:

Specifiation:
• Digital display voltage value: 0~300V, accuracy: Class 0.5. Digital display power value: 0~9KW, accuracy: Class 0.5
• Each preset switch rated voltage: AC 250V, and rated current: 10A, 13A, 16A, 20A four ranges available
• Equipped with a voltage regulating device. It can reach 250V AC voltage required for switching test without connecting external voltage regulator
• Adjustable input voltage to ensure test voltage AC 250V
• All working parameters are set according to AC 250V, including W, I_peak, I^²t and current surge waveform. This load has preset the load conditions required by the standard before leaving the factory. As long as the test voltage is adjusted to AC 250V, the operator presses the same switch button as the rated current of the switch to be tested, it’s rated power, surge waveform, I_peak and I²t will meet standard requirement.
• Convenient and intuitive to use: Digital input voltage and output power, and the pointer type ammeter can observe the current impact.
• The number of work stations is 3: it can test 3 switches at the same time.
• Each set of equipment provides a closing control device, which is turned on at a 90-degree angle each time. This function can be used for initial equipment calibration and measurement verification
• With metering mode and metering dedicated port, built-in 90-degree closing board, convenient to measure the output waveform. The I_peak current value and I^²t energy value fully meet the standard requirements for equipment measurement. (P.S. The I^²t energy value need to use LISUN OSP3104ET Digital Oscilloscope to calibrate)
• With long-break/long-pass protection function, protection time:1~99s can be preset. There will be an alarm prompt if shutdown during protection
• Power supply：Single Phase AC 220V/50Hz

Refer to the IEC Standard：The current peak value of the type of power distribution system corresponding to the load test of this device is as in IEC60669-1:2017 Table 19:
