Overview
Features
Voltage/thermometer unit
When monitoring the status of each cell of the battery pack is required, install the optional voltage/ thermometer unit OP02-PFX. By installing OP02- PFX on PFX2512/2532, voltages/temperatures for four cells are able to be monitored/logged with one sheet, respectively. (Up to 3 boards can be installed.) For a battery pack connected in series, monitoring of balance among cells is important. With OP02-PFX, the charge and discharge control can be stopped according to the status of each cell.In addition, it is equipped with a function to stop charge and discharge when the balance beteen the cells in the battery pack becomes large (maximum voltage – minimum voltage). Furthermore, at the time of pulse discharge, voltage can be measured at the same time as the synchronization of all cells for load fluctuations.

*1 You can apply a voltage from -20 V to 22 V. *2 Ambient temperature at 18 °C to 28 °C. *3 The temperature scale conforms to JIS C 1602-1995 (ITS-90). (ITS-90 is an international temperature scale.) *4 Depending on your thermocouple’s specifications (thermocouple class, wire diameter and insulation), the usable temperature range will vary. *5 When the voltage that the thermocouple calibrator produces is measured. *6 This shows the internal sensor performance. This indicates the temperature measurement accuracy of the thermocouple connector. Thermometer accuracy = Measurement accuracy + reference junction compensation + thermocouple tolerance
