The Allen Bradley 20AD027A5AYNANG0 AC drive is engineered for robust motor control applications. Rated for a three-phase input voltage of 480 VAC, it handles a power output of 15 kW (20 HP) with an output current of up to 27 A under continuous load.
This drive demonstrates impressive overload capabilities, providing 110% overload for up to one minute and up to 150% for three seconds to accommodate short-term power requirements. Users can set two acceleration and deceleration times independently, giving flexibility for specific application needs from 0 to 3600 seconds.
Rated for operating conditions between 0°C and 50°C without derating, this unit is suitable for various environments. It also incorporates encoder feedback with a quadrature of ±27° to assist in precise motor control.
In terms of performance frequencies, the drive operates with a carrier frequency of 2-10 kHz under standard control and 2-12 kHz in vector control mode, enabling effective motor management. The construction includes a brake IGBT; however, it lacks an internal brake resistor. Additionally, this model does not have any internal communication module, which could simplify the control setup. The enclosure type is rated as IP20 or NEMA Type 1, suitable for limited protective applications against dust and moisture.
