TEST SET UP FOR COMPLETE LED LUMINARY FITTING

SCR ELEKTRONIKS make PC based ELECTRICAL SAFETY TEST EQUIPMENT for LED LUMINARY is an application specific, customised & automatic test bench for testing of LED based LUMINARY.

Features

The test system comprises of:
1. Earth Bond Tester: An AC current source (maximum 6V) settable between 2 & 20A is
provided (pre-set to 10A) for this application. The resistance is calculated and displayed
on meter. The resistance limit is settable with pot-meter, normally 1Ω.
2. High Voltage Tester: This is for Hipot Test from 0 to 1.5kV or 0 to 4kV selectable by
switch. The tripping currents are 2, 5, 10, 25 and 50mA can be selected through switch.
Fault Indicator to confirm test results on bench and same is available in TestWare.
3. Insulation Resistance Tester: This test is conducted at 500V DC, with measuring ranges
from 0.1MΩ up to 20MΩ and selectable tripping levels- 1, 2, 5, 10, 20MΩ. Fault/Pass
Indicator to confirm test results is available in on bench & in TestWare.
4. Leakage Current Tester: This test is carried out simultaneously with Performance Test at
nominal voltage. The test is carried out for both supply polarity.
5. Lamp Burning (Glowing) Test: The voltage is increased gradually and the value at which
the lamp glows is noted.
6. Performance Test:
This test includes:
a. Limiting Low Voltage Test: This is for measurement of DC output (voltage &
current) at specified low input voltage.
b. Limiting High Voltage Test: This is for measurement of DC output (voltage &
current) at specified high input voltage.
c. Nominal Voltage Test: This is for measurement of DC output (voltage, current &
power) at nominal input voltage, AC input voltage, current, power, and power
factor.
The equipment has a Programmable (Solid State) AC Voltage Source. This is a programmable voltage
source with settable voltage & settable rate of rise of voltage between 20V & 350V at 40, 50 or
60Hz. The output voltage, current, wattage and power factor are displayed on meter and are
available on PC based TestWare. This source is used for:
Performance Test at Limiting Low Voltage, Limiting High Voltage & Nominal Voltage
a. The “limiting low voltage” is adjusted and DC current & voltage is measured, stored
and compared with set limits.
b. The “limiting High Voltage“ is adjusted and DC current & voltage is measured, stored
and compared with set limits.
c. The “Nominal Voltage” is adjusted and DC current & voltage is measured, stored and
compared with set limits. The leakage for both the polarities is measured during this
test.
