20DR156A3ENNACNAN

The 20DR156A3ENNACNAN model, crafted by Allen-Bradley, operates as an adjustable frequency AC drive specifically engineered for industrial use. Rated at 650V DC, it suits three-phase power applications and possesses the capability to manage input currents of 156 amps. Its design ensures efficient energy management and precise motor control, which are crucial for effective automation systems.

Housed within an IP20-rated enclosure that conforms to NEMA Type 1 standards, this drive offers adequate protection for typical indoor environments. User interaction is facilitated by a comprehensive full numeric LCD, allowing operators to monitor and adjust settings effectively.

The absence of an integral braking system is compensated by an adjustable bus undervoltage trip feature, which safeguards operations by ensuring that the drive functions within safe voltage parameters. In terms of thermal management, the model includes a heat sink thermistor that is continuously monitored by an embedded microprocessor to prevent overheating and ensure reliability.

With a logic control ride-thru capacity of 0.25 seconds while the drive is not operational, it is designed to maintain system stability during brief outages. Additionally, it supports a power ride-thru capability lasting 15 milliseconds under full load conditions, guaranteeing uninterrupted performance in critical applications. Overall, the 20DR156A3ENNACNAN is a vital part of Allen-Bradley's PowerFlex 700S series, delivering outstanding control for demanding industrial applications.
