Product Description:

Industrial automation requires the SC4405-01000 Frequency Drive made by Danaher. The frequency drive runs on a 230 VAC power supply that functions through single-phase and three-phase systems. This control device has an output power capacity of 5 kW. It maintains a continuous current delivery of 10 A RMS. The fixed operation point of the internal bus maintains a constant 325 VDC value.

The SC4405-01000 frequency drive operates through switching frequency to deliver stable and uniform performance at 8 kHz. The drive provides exact torque control accuracy, which stays within ±2% of the complete scale operating range. PID tuning operates together with digital servo control in this frequency drive. The device features four digital inputs, which can be programmed along with two relay outputs, 24 VDC at 1 A. The SC4405-01000 frequency drive enables reception of two analog input channels which operate with ±10 VDC voltage signals. The drive allows integration through RS-232 and RS-485 communication interfaces. It operates with three types of feedback sensors. These are incremental encoders, absolute encoders, and resolvers. All signals moving between I/O modules meet the necessary industrial safety requirements. The drive meets the protection standards of IP20 for control cabinet usage.

The SC4405-01000 frequency drive holds measurements of 200 mm in height with a 100 mm width facing a 150 mm depth. The unit controls its temperature using built-in cooling fans that supply forced air for safe operation under continuous use conditions. The drive works within temperature ranges of 0°C to 50°C while it remains in storage between -20°C to 70°C. The wide applicability of this frequency drive arises from its features that accommodate various motion control systems. The equipment provides 20 A peak currents and permits short-term overloads at 200% during a maximum duration of 3 seconds.
