Programmable resistive load module (hereinafter referred to as resistive load) is a linear analog load for electronic products such as UPS power supplies, inverters, and photovoltaic simulators. By simulating the linear load characteristics of computers, network communication devices, etc., precise control of power output power and quality can be achieved. This product is widely used for performance testing and aging testing of DC current electrical products with linear loads in power, shipbuilding, broadcasting, telecommunications and other departments, as well as UPS, inverter, switch power supply and other manufacturers. It effectively avoids the inability of the tested product to drive the load or cause pollution to the power grid during actual use.

Features:

Modular load design, expandable in parallel

The module has intelligent parallel control. After parallel connection is completed, the PC only needs to send instructions to control the main module, while other modules are controlled by the main module.

Forced air-cooled heat dissipation is safer in electrical terms than water-cooled heat dissipation

Equipped with automatic overload protection function to prevent poor heat dissipation and damage caused by overheating

Protection functions: overvoltage, overcurrent, temperature protection, fan overload protection

CAN communication interface mode

The resistive material adopts new power consuming components with high power density, no red heating phenomenon, and all electric heating elements comply with UL safety specifications;

Load voltage measurement accuracy: 0.1% F.S., current measurement accuracy: 0.1% F.S;

The power connection line of the load module is in the form of a charging gun holder, which can be easily connected without the need for screw operation.
