The DPA-1i instrument is indigenously designed and developed by UMA Electronics to make the testing Simpler, Faster, Accurate, and Reliable with its high performing DSP based circuitry and user-friendly operational features.
DPA-1i Rename now SPPT-1
It serves various industries in Electrical Machines (like Transformers, Motors, Stabilizer), Power Electronics (like UPS, Inverter, Rectifiers), and Lighting devices (CFL, Ballast, LEDs). The high-speed simultaneous sampling using 24-bit ADC ensures True RMS measurement for the wide range of input Voltage and Current. This instrument displays Voltage, Current, Frequency, Active Power, Power Factor, and Apparent Power simultaneously in a 7-Segment Display. The measurement is valid at all power factors and gives accurate results even in the presence of harmonics in the system.
The Meter is provided with a Hold facility. The functionality of the meter is further enhanced with a PC interfacing facility through USB Port. The accompanying software is capable of Data Logging and viewing the Meter Variables in real-time on the computer using the GUI provided.
