STS (Static Transfer Switch)

The DPQ33 Static Transfer Switch provides break-before-make switching between two independent AC power sources for uninterrupted power to critical electronic equipment. The DPQ33 series STS adopts the technology of parallel of Thyristor and AC contractor, producing high levels of power availability and power system tolerance. The switch is suited for data processing, distributed computing, telecommunications equipment, and high-tech manufacturing applications. Features include: Modular structure: The DPQ33 series STS is in the modular structure , including monitor unit, input unit and output unit.Transfer time :0.4ms maximum transfers between AC power sourcesManual and automatic transfersWorking modes: one source works as priority or non source works as priorityDisplaying: Clear LCD monitoring panel with on-screen instructionsMaintenance: The switch permits maintenance without shutting down critical equipment.
