The Allen Bradley 20BD156A3AYNARA0 model is a sophisticated adjustable-frequency AC drive belonging to the PowerFlex 700 series. It is engineered for robust performance and is designed for typical operating conditions with temperature capabilities from 0 to 50 °C and a maximum altitude limit of 1000 meters.
This drive is known for its impressive efficiency, achieving approximately 97.5% in energy conversion. Its output voltage range spans from 0 to 460 V AC, which is essential for accommodating varying load demands. Additionally, the switching frequency of the device can be set anywhere between 2 to 10 kHz, providing flexibility in motor control.
When it comes to handling overloads, the drive can sustain current levels of 188 A for a duration of 1 minute and up to 250 A for short bursts of 3 seconds. The input supply requirement is pegged at 480 V with a three-phase system operating at 60 Hz. Rated output current falls at 156 A while the drive effectively manages motor power ratings up to 125 HP.
User interface is efficiently designed using an LCD keypad, simplifying operation and monitoring. The braking circuit features a Brake IGBT, ensuring controlled stopping of the motor. Moreover, the unit ensures compliance with electromagnetic compatibility (EMC) regulations by including both a filter and common mode choke.
For the control voltage, it operates at 24 V AC/DC. The DC bus hold-up capability allows a transient range of 0.5 to 2 seconds. The DC bus limits are defined at 810 V and 305 V DC, enabling safe and reliable operation in diverse applications.
