LT-DC05 Battery short circuit tester

The product description

1. Test Purpose: Remote control high current short circuit device is designed to meet GB\IEC\EN\UN38.3\UL and other standards based on a variety of battery short circuit test standards. According to the standard requirements, the short-circuit device must meet the internal resistance range is far less than 100mΩ, to obtain the maximum short-circuit current required by the test.

2. Product Description: This machine is a remote control high current short circuit device, which is designed by integrating various battery short circuit test standards and requirements. According to the standard requirements, the short-circuit device must meet the internal resistance range *100mΩ below, to obtain the maximum short-circuit current required by the test. The circuit design of the short circuit devices also must be able to withstand the impact of high current, so we will choose industrial-grade copper dc electromagnetic contactor and terminal and internal copper diversion, built-in active ball bearing axial flow fan to provide effective thermal protection, which will lead to large current short circuit devices more secure, and effectively reduce the wastage of the testing equipment, to ensure the accuracy of the test data.
