E-LIGHT Lamp Constant Temperature and Durability Testing LaboratoryThis is a specialized testing equipment designed and manufactured in accordance with the requirements of clause 12.3.1 of GB7000.1-2002 standard.
This device can achieve environmental temperature control for lamp testing, using circulating heating or cooling of indoor air and advanced PID control technology to stabilize it within the set range. This device uses a regulated power supply for testing input, with 4 or more independent adjustable outputs; Each output has independent voltage regulation and voltage indication; Each group outputs independent current indication, working status monitoring, and working time indication.

Specialized control software monitors the working status, and users can independently set the voltage and testing time control (startup time, shutdown time) and counting control for each test power supply according to actual needs; Multiple on-off cycles can be set for work and time settings for work cycles (such as 21H power on, 3H power off, 10 cycles or 1-hour power on, 2-hour power off, 100 cycles); The equipment has fault detection functions such as over temperature detection, open circuit detection, and short circuit detection, and analyzes the causes of faults while generating different sound and light alarms based on different faults.

3.Test rack type: Three layers in total, each layer24Group power socket, floor height400mmThe installation board adopts insulation board.
4.Each output has independent voltage regulation and voltage indication; Each group outputs independent current indication, working status monitoring, and working time indication.
1)Test cycle setting:0-10000One.
2)Power on time setting:0-99999minperhapsH.
3)Power outage time setting:0-99909minperhapsH.
5.Each test rack is equipped with a monitoring box on the side, which can independently adjust the voltage of the twelve test positions on each layer, indicating the on/off status and direction of each test outputPLCProvide the working status of each group of ports.
3、 Control system functions:
1.Each control box is equipped with three voltage regulators, which adjust the voltage of each layer of the test rack. The test voltmeter adopts a digital voltmeter, which can set low voltage alarm and high voltage alarm.
2.Each layer of twelve test positions uses a contactor, which controls the on/off of each power supply group by controlling the contactor.
3.Each testing station is equipped with a current monitor, and when a testing station has a fault, its signal is fed back toPLC.
4.The current detector uses a magnetic ring induction coil to sense the signal, which is amplified by the signal line and isolated by an optocoupler before being fed backPLCAt the same time, the control panelLEDindicator light; Each board12A testing position.
5.Composition of control system:PLC+7Inch or 10 inch color LCD touch screen.
6.Each workstation has twoLEDIndicator light, the green indicator light is on during normal testing, and the red indicator light is on when there is a fault during testing.
7.When there is a fault in one of the test positions on the same path,PLCRecord the power-off time of the test position, and continue testing the other test positions.
8.Control system composition: MitsubishiPLC+brand7Inch color LCD touch screen.
4Control function:
