BTA20.2
BTA20 Machine Control Boards
The BTA20.2 from Bosch Rexroth Indramat is a high-performance member of the BTA20 Machine Control Boards series, designed for robust AC power management in demanding industrial automation environments. This through-hole mounted control board features bidirectional polarity and an insulation voltage of 2500 V(rms), ensuring safe operation under high-voltage conditions. It supports a continuous RMS on-state current of 20 A and tolerates a peak repetitive off-state voltage of 600 V, while its peak non-repetitive surge current of 200 A provides resilience against transient overloads. The device operates reliably across a junction temperature range of –40°C to +125°C, making it suitable for extreme thermal environments. Its compact form factor and through-hole mounting design simplify integration into existing control panels and power modules.
Performance and dynamic switching characteristics are defined by a gate trigger voltage of 1.5 V paired with a gate trigger current of 35/50 mA to guarantee precise turn-on behavior. A holding current of 60 mA ensures stable conduction, while the latching current of 80 mA secures a reliable transition from off-state to on-state. The critical rate of rise of on-state current is rated at 50 A/µs, enabling the board to handle rapid current transients without spurious switching. Leakage is minimized by a typical off-state leakage current of 2 mA, reducing standby losses and improving overall system efficiency. These technical features eliminate the need for complex external commutation networks and support tight control loops in high-speed switching applications.
Built for longevity and seamless system integration, the BTA20.2 meets UL insulation standards and requires no external snubber circuits, streamlining component count and board layout. Its rugged construction and extended temperature rating deliver consistent performance in harsh industrial settings, from motor drives to heating and lighting control. The device’s factory-assigned configuration and design facilitate quick specification and deployment in modular automation architectures. Ideal for OEMs and system integrators, the BTA20.2 excels in precision power control, offering a reliable solution for manufacturing equipment, process control systems, and energy management applications where durability and accuracy are paramount.
