Product description
The ABB ETP90H-4G50 is a powerful pressure transmitter manufactured by ABB. It is designed to monitor and control pressure changes in various industrial processes.
Product parameter
working principle : AC servo working principle, with three-phase sinusoidal current drive output .
working environment : The drive can work normally under the condition that the ambient temperature does not exceed 55℃.
protection function : the circuit board adopts three anti-treatment, with overheating, overvoltage, undervoltage, motor short-circuit and overcurrent protection function .
power input : Input power of the driver is 110VAC or 220VAC, the range is -30% to +20%.
easy connection : only 3 wires are used between the motor and the driver to reduce the possibility of connection error .
Advantages and characteristics
High precision : ABB ETP90H-4G50 provides high precision pressure measurement to ensure the stability and reliability of industrial processes .
strong anti-interference capability : the circuit board three anti-treatment and a variety of protection functions, so that it can run stably in harsh industrial environment .
high starting frequency : Because the driver adopts sine current drive, the no-load starting frequency of the motor is as high as 4.3 to 5.3KHz.
position hold function : when the motor is powered on and off, the position of the motor remains unchanged, and the position of the motor is also unchanged after power failure, which brings great convenience to the work .
