Two Channel DC Voltage and Current Data Logger records DC voltage and DC current (avg, max and min) at high accuracy. The voltage and current logger is provided in a comprehensive kit which includes the data logger, a DC current probe, three fused voltage leads, a USB lead, a 12Vdc PSU and FREE software—all for one low price. This model is specifically designed to accurately monitor one or two DC voltage channels from 1V to 300Vdc, and one DC current channel (+/-10A or +/-100A). This enables many battery testing applications including monitoring PV (photovoltaic) cell output, DC charger performance, and other uses including equipment monitoring of DC motors. 

For reliable protection from dust and damage, the data logger is rated IP65, with NEMA 12/4 rated versions also available. Users can select an averaging period to suit each situation, accurate to <1% of range. When recording, the DC logger will store the average DC voltage and DC current over the period chosen (user-settable from 1 sec to 60 min), and will also record the highest and lowest values during that period. Memory capacity is 32,000 true RMS values per channel (10 bit), providing up to 300 days of continuous recording. All the stored data is uploaded to a PC via the supplied USB cable, and for simple storage, the data logger fits easily into the included carrying case. Additionally, FREE software loaded with features is provided to upload the USB logger’s recorded data to a PC. This setup software allows users to export data files as well as plot graphs showing energy/power costs and find savings using voltage optimization techniques. The software also features a database which can be used across a network to track the logger’s location and enables alarms for late returns, emails data files, and prints report-quality graphs. Users can draw electrical line diagrams, view print previews and output to PDF, RTF, XLS, HTML, etc.
