Three phase network analyzer with display
KET-PMT-300 is a three phase network analyzer with a built in backlighted display to show measured values. Direct access to setup is provided through local menu.
The analyzer can be used for current reading using Rogowski transducers and is suitable for voltage range up to 600 Vac (50 Hz or 60 Hz).
The following electrical values are provided: Vrms, Irms, Watts (bi-directional), Var, VA, frequency, Cosφ, bidirectional energy.
All values can be acquired via serial communication both in floating-point format that normalized.
KET-PMT-300 is equipped with CANopen, RS485 and UART-TTL communication ports.
