Unipower APM380 is an electronic measurement transducer that measures power in kW on 3-phased asymmetric loads, also after frequency inverters, according to the formula:
P = √3 x U x I x Cosϕ
* Suitable for mains voltages from 3x230V to 3x575V
* Measures after frequency inverters; PWM 10Hz - 1kHz
* 10 ranges for currents up to 80A internally
* 0(4)-20mA and 0(2)-10V analogue outputs
* Programmable filter function
* Galvanic isolation between mains net and I/O (incl. 24V)
* Prepared for control functions and serial communication.
