AC Power for Business-Critical Continuity™ Liebert STS (10A & 16A) Power Redundancy for One-way Power Supply The STS is a kind of single-pole automatic transfer device with the capacity of 10 / 16A. It performs the core functions of detection and transfer in the dual-bus system composed of two ways of AC power, and is used in the high-end uninterruptible power supply applications that require high power supply reliability. Features The key component in the system, the auxiliary power, adopts redundancy design to ensure that the equipment can still operate normally upon the failure of one single power. Full DSP control ensures strong data processing capacity and improves the system reliability. Advanced power-off detection method enables quick judgment of power-off failure. Powerful communication function realizes the remote management through SNMP card (option) Redundancy The main power and the standby power can directly connect to the STS on the rack, and the STS can provide redundancy control on the power. Once the main power fails, it will automatically switch to the standby power. Reliability The STS adopts the control technology of“First Disconnect Then Connect” If one-way power fails, the STS can ensure the uninterruptible power supply to the equipment through the other way of power. Once short circuit occurs, the STS can ensure that the failure will not extend to the standby power, and thus ensure the uninterruptible power supply to the equipment. The Liebert STS Is Ideally Suited For: Computer equipment rooms Internet data centers Telecom & financial data centers Industrial process control centers Liebert STS Specifications Model Number 02352247 02352244 02352190 IEC309 x 2 IEC-C20 x 2 Input Input Connectors C14 x 2 Rated Voltage 220 /230VAC Rated Frequency 50 / 60Hz Voltage Range 150 to 300VAC Frequency Range 50 / 60Hz ± 5Hz Voltage Distortion < 10% Output Output Connectors C13 x 6 C13 x 6 + C19 x 1 Power Factor 0.75 to 1 lead or lag Overload Capacity 125% for 30 minutes Efficiency 99% Transfer Number of Poles Automatic Transfer Interval 2 poles < 6ms typical, < 11ms max Environmental Parameters Operating temperature Storage temperature Relative humidity Elevation 0 to 40°C -40 to 70°C 5 to 95%; no condensation 3000m Mechanical Parameters Dimension H × W × D (mm) Net weight of standard equipment Gross weight with options 44 × 430 × 250 4.5kg 5kg
