Description
SW1001 Switch Mainframe for High-Precision Multi-Channel Battery Testing
The SW1001 Switch Mainframe from Hioki is an essential solution for laboratories and production facilities needing efficient multi-channel battery testing. By housing up to three SW9001 or SW9002 Multiplexer Modules, the SW1001 enables simultaneous measurement of OCV, internal resistance, external potential, and low-frequency AC impedance for battery cells up to 60 V DC.
Designed with precision in mind, the SW1001 reduces measurement errors across channels by minimizing magnetic flux interference and separating source from sense signals. This circuit-friendly design ensures high accuracy for impedance measurements, with an effect as low as 0.01% full scale when paired with BT4560 battery testers.
The switch mainframe allows connection of up to two measuring instruments, enabling flexible testing setups. Users can switch between instruments for different measurement types without interrupting the workflow. Its scan function automates channel selection and triggers synchronized measurements, streamlining large-scale testing operations.
A dedicated PC application makes setup, monitoring, and data management simple. Additionally, the SW1001 reduces the number of communication ports required, transmitting commands from the PC to the measuring instrument directly, which simplifies system integration and reduces cable clutter.
With channel switching as fast as 11 ms and compatibility with both 2-wire and 4-terminal pair configurations, the SW1001 Switch Mainframe is ideal for high-precision multi-channel battery evaluations, identifying defective cells, and investigating the causes of battery performance issues. When combined with multiplexer modules, it scales testing capabilities efficiently, making it indispensable for R&D, quality control, and production line battery testing.
