The DPA-1 instrument has been designed and developed by UMA Electronics to make testing simple, fast, accurate and reliable with its high-performing DSP-based circuitry and user-friendly operational features. It serves various industries in electrical machines (such as transformers, motors, stabilizers), power electronics (such as UPS, inverter, rectifier) ​​and lighting devices (CFL, ballast, LED). High-speed synchronous sampling using 24-bit ADC ensures true RMS measurement for a wide range of input voltage and current. The device displays volt, current, frequency, active power, power factor, and current power simultaneously in a 7-segment display. The measurement is valid on all power factors and gives accurate results even in the presence of harmonics in the system.
