Test Purpose
The dynamic mechanical load tester is used to verify the ability of components to withstand static and dynamic loads under conditions such as wind or ice. This machine is used to test the compressive strength of photovoltaic modules, using dynamic pressure holding technology, simulated load test, to evaluate the product under load state, compressive ability.

The system realizes the simulation of dynamic load in the form of cylinder & sucker, Pressure mode sucker + pressure sensor + cylinder + proportional valve +PLC. Each cylinder drives a sucker, and each cylinder piston rod is installed with a tension pressure sensor. The air pressure is calculated by PLC according to the real-time feedback value of the pressure sensor, and the cylinder movement is controlled by adjusting the opening of the proportional valve, so as to achieve the control of the force value. Each cylinder is a separate control module. Periodic load pressure tests are performed on the mounting plane of the component. The main frame of the system is 8080 European standard aluminum profile design, taking into account the installation of conventional components, the installation of screw holes and the installation of double glass components. The device also provides real-time monitoring of component shape variables as well as current continuity and component temperature during testing.

Product Features
- The control software synchronously collects the pressure of each cylinder, solar panel pressure, panel temperature, continuous current, panel voltage, shape variable and other information
- Humanized human-machine interface graphics, the current can be set arbitrarily, which can meet the diverse needs of customers
- Visual ICONS and EXCEL output form to meet the diverse needs of customers

Product Introduction
PID power supply has multi-channel output, can provide multiple components simultaneously test, voltage can be continuously adjusted voltage parameters can be displayed in real time.

PID monitoring communication and according to the customer's self-defined time requirements, the system output high voltage to test the tested products. The system can monitor the internal temperature and humidity of the environmental test chamber according to the latest standards (on-line communication with high temperature dehumidification equipment).

When the environmental test chamber fails, the PID power supply will automatically receive the fault information of the environmental test chamber. The software will force the power system output to "0" to avoid damage to the remaining test samples and equipment safety due to the incompatibility of the two systems.

Power supply has current alarm function, alarm can be set pattern.
