Electrical Safety Test Equipment for LED Luminary

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. It combines the following tests

• Earth Bond (Contact Resistance) Test
• High Voltage Test
• Insulation Resistance Test
• Leakage Current Test
• Lamp Burning Test
• Performance Test

The test equipment is a solution for manufacturers, OEMs and laboratories who want to test the safety conformance of LED based Luminaries on manufacturing line & check compliance of LED based Luminaries to standards.

The test system comprises of:

1. Earth Bond Tester: An AC current source (maximum 6V) settable between 2 & *0A is provided (pre-set to *0A) 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, *0, *5 and *0mA 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 **0V DC, with measuring ranges from 0.1MΩ up to *0MΩ and selectable tripping levels- 1, 2, 5, *0, *0MΩ. 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:

1. Limiting Low Voltage Test: This is for measurement of DC output (voltage & current) at specified low voltage.
2. Limiting High Voltage Test: This is for measurement of DC output (voltage & current) at specified high voltage.
3. Nominal Voltage Test: This is for measurement of DC output (voltage, current & power) at nominal voltage, AC 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 *0V & **0V at *0, *0 or *0Hz. 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

1. The limiting low voltage is adjusted and DC current & voltage is measured, stored and compared with set limits.
2. The limiting High Voltage is adjusted and DC current & voltage is measured, stored and compared with set limits.
3. 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.

PC with TestWare: This is standard PC with Interface system & TestWare software tailored for automatic data-logging & report generation
