Product description
The SZR-16A automatic power transfer switch is designed for use in 230 V AC power supply systems. The device supports a rated voltage range of +10% / –15% at a frequency of 50 Hz and a maximum load current of up to 16 A. In the event of a main power failure, it automatically switches the power supply to the backup circuit, ensuring uninterrupted operation of the loads. A switching time of up to 40 ms minimizes power interruptions. LED indicators provide a quick overview of the voltage status at the inputs and output, facilitating system diagnostics. The device also allows for manual disconnection of a selected input for maintenance or testing purposes. The compact housing, measuring 85.5 × 83.3 × 67.5 mm, and TS35 DIN rail mounting allow for easy installation in control cabinets and switchgear.
