IEC60669-1 Clause 19.3 Self Ballasted Lamp Load Box SBL Switch Tester 250V
Switches intended for self ballasted lamp (SBL) loads shall withstand, without excessive wear or other harmful effect, the electrical and thermal stresses occurring when controlling self ballasted lamp circuits.
Compliance is checked by connecting the load as given in Figure 12b via the switch under test to a power supply.
The calculations are based on the following parameters in order to have the required values for inrush current and I 2 t:
– a prospective short-circuit current (rms) of the supply of 3 kA at cos ϕ = 0,9 (lagging);
– a resistance R 3 equal to 0,25 Ω in the test circuit to the load. This value is obtained with a wire having a cross-sectional area of 1,5 mm 2 when switches with rated current up to and including 13 A are being tested and 2,5 mm 2 when switches with rated current over 13 A up to and including 20 A are being tested.
Standard: IEC60669-1:2017 clause 19.3
Application: This device is suitable for breaking capacity and normal operation life test to fixed switches for house held and similar purpose, especially suitable for self ballast lamp switch electric stress and thermal stress test when control the LED circuit. To verify whether the switch can withstand normal use, any mechanical damage or electrical fatigue failure under normal operation, any contact adhesion phenomenon or long term closure or disconnection phenomenon, to test whether excessive wear or other harmful consequences.
Test sample: Self Ballast Lamp(SBL) Switches
Feature: Dimension about: wide (800mm) * Deep (800mm) * high (1800mm). The frame is blue and the side panels are light white. Above the front is the operation control panel. On the control there are power switch, product test voltage and power display instruments, alarms, touch screen, etc., there are resistors and capacitor load combinations, AC contactors, relays. There is a terminal under the box, which is connected to the product in the testing machine through the wire, and outputs current and provides load in the inspection process.
The load device has been preset with standard load conditions before shipment. As long as the test voltage is adjusted to 250V~, the operator presses the switch button with the same rated current as the switch to be tested, and its rated power, impulse waveform, Ipeak and I2t meet the corresponding requirements of the standard.
There are 3 stations and 3 switches can be tested at the same time.
With metering mode and metering dedicated port, built-in 90-degree closing plate, easy to measure the output waveform, Ipeak current value and I2t energy value, fully meet the standards for equipment measurement requirements.
The device is equipped with a voltage regulator, which can reach the voltage of 250V required by the switch test without the need of an external voltage regulator.
