DIV-503A
On-vehicle High Voltage Data Logger for Crash Test

Summary

This logger has 980.7m/s2 (100G) impact resistance, and can safely measure the high voltage signals such as those of batteries used in electric and hybrid vehicles.
Between input channels are insulated, therefore this can safely measure the high voltages of batteries used in electric and hybrid vehicles during crash tests.
There are two measurement methods. One is unit acquisition mode (maximum 20kHz sampling) that records within the logger data which is recovered after testing, and the other is PC acquisition mode (maximum 100Hz sampling) that transmits and saves data on a connected PC in real time. This means that unit acquisition mode can be used during crash tests, and PC acquisition mode can be used during voltage monitoring and other preparations.

Features

●Measurement range ±500VDC/±250VDC
●At sampling frequency 20kHz, measurement for approximately 62 seconds, and at 100Hz, for approximately 8 hours (PC acquisition mode).
●Real-time measurement possible (sampling frequency 100Hz or less)
●Frequency characteristics are DC to 1kHz
●Measurement: 3 channels
●Maximum sampling frequency 20kHz
●nput level display LED built-in
●Use of 100BASE-TX for high-speed data transmission possible
