DS POWER 300HT

Product catalog summary

General Specifications:
The DS Power range UPS by TescomR offers advanced features such as galvanic isolation at output, low input current total harmonic distortion (THD), high input power factor, and efficiency up to 94%. It includes a cold start function, static and maintenance bypass switch, and output short circuit and overload protection. The system supports external REPO switch input, has a memory for 512 events, and features a clock and calendar supported by a battery. An automatic battery test and remaining battery time indicator are included, with an optional temperature-compensated charge system. The UPS is equipped with 2 RS232 serial ports, 12 dry contact outputs, and a modular structure controlled by DSP. Optional features include SNMP and MODBUS adaptors, a graphical panel, and ecomode operation. The system is designed with fewer electronic components, advanced diagnostics, and selectable input/output voltage/frequency/range. It also includes split bypass input, output DC leakage protection, and separate DSPs for inverter and PFC control. The UPS offers high charge current capacity, advanced remote control features, and is manufactured according to EC Directive EN62040 with a 2-year warranty.

Technical Specifications:
The DS Power range covers models from 10 to 500 kVA, with input voltage options of 380/400 VAC and a frequency of 50Hz/60Hz. The power factor is ≥ 0.99, and THDI is ≤ 3%. The output voltage is 380/400 VAC with a frequency tolerance of ± 2% line synchronized and ± 0.1% free running. Efficiency reaches up to 94%, with overload protection for various load percentages. Battery specifications include VRLA AGM/GEL/NiCd types, nominal voltage of ± 336 VDC, and external battery cabinets. The system supports automatic testing every 72 hours and includes multiple protections. General features include compliance with EN62040 standards, a user interface with an LCD panel, and advanced self-diagnostics. Communication options include RS232 ports and dry contact alarm relays. The system operates within a temperature range of 0ºC to 40ºC, with a protection degree of IP20 and a maximum relative humidity of 90%. Acoustic noise levels vary by model, and the system supports parallel operation up to 8 units.

Options:
Optional features include different input/output voltage configurations, a galvanic isolation transformer at input, and various software and adaptor options for enhanced monitoring and control.

DATA CENTER MALLS & FACILITIES DS POWER 300HT 10-500kVA Galvanic Isolation at Output IGBT Rectifier DSP Control SERVICE / TECH. SUPPORT POWER FACTOR DS Power range UPS uses the latest DSP technology to be programmed to suit a wide variety of electrical environments without impending its performance. With the DS Power range, efficiency, reliability and functionality are enhanced to levels unattainable with the old analogue technology. This technology does not only create significant increase in MTBF, but the capability of DSP to accurately manipulate signals at very high speed permits all the UPS subsystems to be controlled with greatly increased precision.
