Key Features
ABB DSSR 122 48990001-NK can Pulse Width Modulation Technology with a switching frequency of 350 kHz, achieving a conversion efficiency exceeding 85%. And accept low-power operation to minimize energy loss. The built-in power factor correction circuit optimizes energy utilization, reduces harmonic pollution, and meets green energy-saving requirements.
ABB DSSR 122 48990001-NK is capable of Modbus and Profinet communication protocols, connecting to PLCs, HMIs, and other devices for remote monitoring, fault diagnosis, and real-time data acquisition.
ABB DSSR 122 48990001-NK supports parallel operation of multiple modules to enhance system fault tolerance, using high-quality capacitors and semiconductor components, achieving an average mean time between failures (MTBF) exceeding 100,000 hours.
ABB DSSR 122 48990001-NK features multiple protection mechanisms:
Overvoltage protection: Automatically cuts off output when output voltage abnormally increases to prevent equipment damage.
Overcurrent protection: Monitors output current and triggers current limiting or shutdown when exceeding the rated value.
Short-circuit protection: Rapidly responds to load short-circuits to prevent module burnout.
Over-temperature protection: Built-in temperature sensors automatically reduce output or shut down the unit when temperatures rise excessively.
