PSTX470-600-70

The ABB PSTX470-600-70 is an external braking chopper module (also known as a brake IGBT) designed for use with ABB drive systems. Its core function is to safely dissipate regenerative braking energy to prevent overvoltage on the DC bus of a variable frequency drive system.

Key Specifications Parameter Category Specification Product Type Braking Chopper Module (External Brake Unit) ABB Series / Model PSTX470-600-70 DC Bus Voltage Rating 600 V DC Continuous Braking Current 70 A Peak Braking Current Typically 140-150 A for short durations (e.g., < 2 seconds). Refer to the datasheet for exact duty cycle and peak current specifications. Control Logic Voltage threshold-based activation. Turns ON when DC bus voltage exceeds a set level (e.g., ~760-780V for a 600V nominal system) and turns OFF when it drops below the reset level. Power Connection Connects in parallel to the positive (+) and negative (-) terminals of the shared DC bus of the drive system. Resistor Connection Terminals for connecting an external braking resistor. The resistor is not included and must be sized separately based on the required braking power and duty cycle. Status Indication Typically includes LED indicators for power and fault status. Key Features • Designed for integration with compatible ABB multidrive systems (e.g., ACS880 cabinet-built drives). • Provides reliable overvoltage protection for the DC bus. • Compact, cabinet-mountable design. Protection Features • Thermal overload protection for the IGBT. • Short-circuit protection for the braking resistor circuit. Mounting Cabinet mounting (IP00 chassis). Must be installed inside a suitable electrical enclosure. Core Application Safely dissipating regenerative energy in VFD applications with frequent braking, deceleration of high-inertia loads, or overhauling loads (cranes, centrifuges, test benches, downhill conveyors).
