A battery analyser and data logger in one
13 June 2015
New from Aspen Electronics, the WENS 900 Series analyser and data logger for UPS battery field management provides a single, quick, test to show the health of the battery at variable loading conditionings for impedance, voltage, temperature and current measurements.
The WENS 900 provides abundant data logging and accurate trend analysis; unit has an internal SD card back-up to store up to 100,000 data readings. Data is available in both text and graphic mode.
The unit measures internal resistance, open-circuit voltage and terminal temperature of secondary batteries, including lead-acid batteries, nickel-cadmium batteries, lithium-ion batteries and nickel-metal hydride batteries.
It has an ac four-terminal method to measure the internal resistance by eliminating lead resistance and contact resistance to get the accurate results which are simultaneously displayed along with voltage and temperature.
There are 99 sets of composite comparator functions, which can be set at resistance and voltage values to get reliable detection of battery deterioration. Integral with the unit are pin type leads, supplied as standard, for easy contact with the battery electrodes to get a more accurate connection.
Four-terminal measurement is possible and there is a clip type lead with temperature sensor and a clamp adaptor for dc current measurements. There is a dual display to show the internal resistance and voltage of the battery simultaneously.
