- Generally, Static transfer switches are electronic devices that seamlessly transfer critical loads to either of two independent AC power lines. The system monitors two AC inputs and if any of them goes out of the specified tolerance, it transfers the critical load to the other. However, STSREG31; Static Voltage Regulators with 3 phase Input selector; It is a system that is fed from the 3-phase electrical network and transfers it to the loads it feeds by selecting the best of the 3 phases in order to ensure continuous regulated feeding of critical loads fed by 1 phase at its output. If we need to examine the system by dividing it into 4 parts;
- Input 3 Phase Selector Static Transfer System that can serve in the 50-300VAC input voltage range; It selects the phase of the 3-phase AC energy source at its input that best suits the set technical values and sends it to the Output Channel as the supply of the Static Voltage Regulator with 1-phase AC input at its output. If the selected phase goes outside the set technical tolerances, the Static Transfer System automatically transfers the load to the most suitable one among the other phases.
- Single phase Static Voltage Regulator It is a new generation thyristor-controlled AC Voltage regulator that puts the 90-280 VAC input voltage range into the 220VAC +/_3% Output voltage range with a correction speed of 20 Milliseconds.
- Manual Bypass For Maintenance Purposes. It connects a selected phase of the network at the input and the output channel. In position -0-, no load is connected to the STSREG31 system. In the -1- position, it bypasses the STSREG31 System and connects the L1 input phase to the Output Channel. It is the normal operating position. In the -2- position, STSREG31 connects the regulated output channel to the load.
- Automatic By-Pass to Switch Output When a malfunction occurs in the Static regulator unit within the STSREG31 System, it automatically connects the Static Switch output to the Final output channel.
