MACCOR In-line AC Impedance Measurement System

High Power Module

Series 4300M

Online AC Impedance Measurement

AC impedance (AC Imp) measurements can be performed immediately after charge/discharge cycles without the need to move the device under test.

Using Frequency Response Analyzers (FRA), precise low-impedance readings can be achieved with scanning frequencies ranging from 1 mHz to 25 kHz.

The Frequency Response Analyzer can be integrated with existing Maccor test systems or used as a standalone unit.

Maccor’s FRA is a fully integrated turnkey system capable of executing a wide variety of experiments — including cycle life testing, pulse discharge, cyclic voltammetry, differential capacity, and frequency sweep analysis — using either half-cell or full-cell samples.

8-Channel External Connectivity — Key Benefits:

High accuracy for low-impedance measurements, capable of measuring down to 200 micro-ohms.

Multi-channel transmission system eliminates the need to stop test channels or move samples when switching between measurements, enhancing efficiency.

Seamless switching between samples without disconnecting or reconnecting equipment, reducing measurement errors caused by equipment handling or human operation.

No manual adjustments or keyboard inputs required — simply connect the system and begin testing.

Multiplexed design allows a single FRA to connect with up to 8 test channels.

Parallel testing capability, allowing up to 8 independent experiments to be queued for measurement.

Supports impedance measurements on devices up to 5.5 V DC.
