VR-192GLA-LED-HW adopts VR-ETC75W-4L series electronic load module for pulling, each aging car has 7 layers (the lower 3 layers are 180mm high; The upper four layers are 120mm high). 7 VR-ETC75W-4L load modules are installed on each layer, and a total of 49PCS of modules are installed. VR-ETC752 (G) -4L load module is divided into 4 channels load, CC, CV, LED, mode;

3．The trolley is divided into aging area and load area. The product placement area is about 300mm wide. The product input interface adopts movable wiring strip (including fast clip) to facilitate the fast connection of large and small products. PCB output interface with parallel switch and fast clip, with LED indication;

4．0.5mm high temperature insulated epoxy board is laid on the pallet board to solve the defect of insulation skin shrinkage at high temperature；

5．Aging car is equipped with PC computer, which is used to load monitoring software and control electric control part, can set and display aging current and product output voltage, and has the function of automatic detection and judgment of output voltage and current. Aging current/voltage can be set in layers, one aging car can aging products of seven different specifications at the same time;

6.LED is used to indicate the load status of each load group.

7．Electronic load module has OCP (overload protection function);

 

Electronic load VR-ETC150W-2L main technical parameter：

Aging electronic load VR - ETC75W - 4 L (G) is the main characteristic of switching load flexibility, can unattended operation process, save manpower, optional multimachine parallel function, meet the needs of high-power multiple sets of aging test, load current, soft start function load process will have any impact to the products tested, with stable performance not drift, master modularization, the most simple and convenient operating interface, use convenient adjustment, constant current and voltage (optional) load working mode, main power devices are imported to the United States and Japan, long life and high reliability, digitally stepless setting load current value; Ultra high brightness LED dual screen displays the set voltage and current value, intuitive and simple, high reliability OVP (over power protection function), fault free interval time (MTBF) up to 87000Hours.
