IEC 60669-1 Clause 19.3 Self-Ballasted Lamp Load Cabinet For Load
Switching Capacity Test
Standard:
IEC 60669-1: 2007 ”Switches for household and similar
fixed-electrical installations - Part1:General requirements” clause
19.3
Product information:
Sample and restrictions: Switches for controlling self-ballasted
lamps.
Test purpose: Used to test the load switching capacity of switches
for controlling self-ballasted lamps.
Test principle: Switches used to control self-ballasted lamps
should withstand the electrical and thermal stresses that occur
when controlling LED circuits without excessive damage or other
harmful effects. The purpose is to assess whether there is
continuous arc flash in the switch, whether the contacts are
welded, whether the contacts are closed or disconnected for a long
time, and whether there is excessive wear and other harmful
consequences.
Equipment structure and characteristics:
The load cabinet adopts an integral steel structure frame and
Toyota white sealing plate. At the top of the front is the
operation control panel. There are control power switches, product
test voltage and power display instruments, alarms and touch
screens, etc. It also contains resistor and capacitor load
combinations, AC contactors, and relays. There are terminals under
the cabinet, which are connected to the products in the testing
machine through wires to output current and provide load during the
testing process. The equipment mainly has the following features:
1. This load cabinet has been preset with standard load conditions
before leaving the factory. As long as the test voltage is adjusted
to 250V~ and the operator presses the switch button with the same
rated current as the switch under test, its rated power, impulse
waveform, Ipeak and I2t will meet the corresponding requirements of
the standard.
2. It is easy and intuitive to use, with digital display of input
voltage and output power, and the pointer ammeter can observe the
current impact.
3. There are 3 stations, which can test 3 switches at the same
time.
4. With metering mode and dedicated metering port, built-in
90-degree closing plate, it is convenient to measure the output
waveform, Ipeak current value and I2t energy value, fully meeting
the standard requirements for equipment measurement.
5. This equipment is equipped with a voltage regulator, and can
reach the voltage of 250V~ required for switch testing without an
external voltage regulator.
Equipment dimensions: Approximately: 800×800×1800 (mm) W×D×H,
Equipment weight: 200kg
Technical parameters :
| Test station | 3 stations, independent output |
| Electrical control method | Touch screen + button control, instrument display |
| Digital voltage value | Range 0～300V, accuracy 0.5 |
| Digital power value | Range 0～9KW, accuracy 0.5 |
| Output voltage | 0-280V adjustable, ensure the test voltage is 250V |
| Preset switch rated voltage | Each channel is 250V, with four optional rated currents: 10A, 13A,
16A, and 20A |
| Working parameter setting | All parameters are set according to 250V, including W, Ipeak, I²t
and impulse current waveform |
| Measurement function | Each set of equipment is provided with a closing control device
(select the "measurement" function on the touch screen). At this
time, it is turned on at a 90-degree angle each time. This function
can be used for initial adjustment and measurement verification of
the equipment. (The measurement method is to derive the current
waveform from an external oscilloscope, and then use the
calculation method to obtain the I2t value. The oscilloscope is
self-equipped) |
| Protection function | With long-off/long-on function, the protection time can be preset
from 1 to 99 seconds, and the machine will stop and alarm when it
is protected. |
