Complete battery quality analysis solution for UPS field management

New from Aspen Electronics is the WENS 900 Series analyser and data logger for UPS battery field management. The unit provides a single, quick, test to show the health of the battery at variable loading conditionings for impedance, voltage, temperature and current measurements (simultaneously or independently) with user-friendly software. The WENS 900 finds application in the field management of almost any battery, including UPS back up batteries in telecom industrial systems, renewable energy power plants (solar, water, wind), marine, aerospace, military, automotive and the like. Providing abundant data logging and accurate trend analysis the unit has an internal SD Card back-up to store up to 100,000 (100K) data. Data is available in both text and graphic mode. The WENS 900 battery quality analyser is designed for measuring the internal resistance, open-circuit voltage and terminal temperature of secondary batteries, including Lead Storage Cells (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. 4-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. Impedance measurement is within the range of 4mohm to 4ohm (4 range)/1uohm resolution (±0.8%rdg to ±10dgts). Voltage measurement with differential input ranges is 4V, 40V and 400V (3 range) (±0.5%rdg to ±5dgts). Current measurement (CT) ranges from 0.5A to 400A (±1%rdg to ±5dgts). DC current (Direct) has a range of 400mA to 4A (±0.5%rdg to ±5dgts). The temperature range is -10C to 100C or 14F to 212F (±1C or ±1F). The unit measures 107m (W) x 220mm (H) x 55mm (D) and weighs just 1.2kg.
