It gives development engineers of EVs, electric trucks, buses, construction, and agricultural vehicles the possibility to accurately monitor the energy consumption under the most extreme temperature conditions.  Exclusively designed to be used with the LR8450 Data Logger Series, up to 55 currents can be logged simultaneously on one device at a bandwidth of up to 5 kHz. Applications range from providing a detailed energy consumption insight of a vehicle under test to other complex electrical systems. The CT7822 with its PL14 connector can be used with the LR8450 Data Logger either in combination with the U8556 Plug-in Current Module or alternatively with the LR8536 Wireless Current Module (requires LR8450-01).

The Z5021 Probe Power Unit for the MR6000 Memory Recorder is a factory-installed option designed to provide power to up to eight current probes or clamps from the CT670x or 327x Series. Additionally, the Z5021 supports up to four CT6710 or CT6711 current clamps. For applications requiring higher voltages the Z5021 can power up to eight 9322 or up to three P9000 Differential Probes. It delivers a stable output voltage of ±12 V DC and a rated output current of 0.6 A per terminal. The Z5021 must be ordered together with the main instrument at the time of purchase. For an installation at a later stage, the main instrument needs to be sent to a HIOKI service center.
