Product Introduction

XL-942S Non-vehicle-mounted Charger On-site Characteristic Tester Integrates functions such as on-site calibrator, power analyzer, oscilloscope recorder, BMS simulator software, vehicle DC interface circuit simulation box, insulation resistance tester, etc. Together with the load, it meets the testing requirements for metrological verification, interoperability testing, and protocol consistency testing, and satisfies the inspection requirements during the acceptance and operation phases of the State Grid Document No. 45. During interoperability testing, waveforms and messages are displayed graphically in real time, making the working status clear at a glance. The device has a built-in WIFI module for wireless data transmission and can be remotely controlled via wireless devices such as tablet computers. Technically, the XL-942S uses cutting-edge technologies to achieve high performance, such as 24-bit sigma-delta AD, imported high-stability zero-flux current transformers, and a dual-core DSP with a main frequency of 500M, making its performance outstanding.

  Main Features

• Built-in recording module with 8-channel recording capability, supporting global waveforms and event waveforms, automatically capturing fault moments;
• Equipped with a database function, test records are automatically generated and can be queried and exported by number, date, and other methods;
• Project editing function available, selectable verification projects, automatic process detection, automatic calculation of minimum time and minimum energy required for verification, saving customers time, money, and effort;
• Built-in insulation resistance testing module with integrated design, no complicated wiring needed, safe and efficient;
• BMS simulator function, which, combined with the load box, can verify working error and display error verification points;
• Built-in WIFI module enables automatic data upload and remote control functions;
• Supports multiple power supply methods, built-in large-capacity lithium battery, outdoor operation without power access, can normally work for more than 8 hours, and the battery is designed to be removable;
• Recording and diagnostic function: supports saving on-site recording data and uses recording diagnostic software to import recording data, display recording waveforms, analyze recording event times, and other functions.
