TOSHIBA International Corp GUIDE SPECIFICATIONS THREE PHASE UNINTERRUPTIBLE POWER SYSTEM TOSHIBA 4200FA 25 kVA CT – Internal Battery UPS GUIDE SPECIFICATIONS 4200FA CT March 4, 2010 1
(25 kVA CT) 1.0 SCOPE 1.1 System This specification describes a continuous duty, three-phase, on-line, solidstate uninterruptible power supply system, hereafter referred to as the UPS. 2.0 SYSTEM DESCRIPTION 2.1 Applicable Standards The UPS shall be designed in accordance with and be compliant with the following sections of the current revisions of the following standards: ANSI C62.
H. Input / Output EMI / RFI Filters 2.3 System Operation The UPS shall operate as an on-line, fully automatic system in the following modes: A. NORMAL - Incoming AC power is boosted using a chopper circuit, and converted into DC power. The DC power is then used to charge the battery bank while at the same time providing clean, DC power to the inverter circuitry. The inverter converts DC power to regulated AC power which feeds the load. B.
protection against spikes, common/normal mode noise, load steps and frequency shifts (without battery back-up capability). 3.0 SYSTEM PARAMETERS A.
+/- 3% (loss or return of input power) +/- 8% (bypass to inverter) 13) Transient Voltage Recovery 50ms maximum to within 2% of nominal 14) Overload Cap. (on inverter) 125% for 90 sec., 150% for 30 sec. 15) Overload Cap. (on bypass) 1000% for 10ms, 125% for 10 min. 16) Crest Factor 2.5 – 3.0 within the kW range. 17) Harmonic Voltage Distortion 1.
4.0 FUNCTIONAL DESCRIPTION A. Converter / Charger / DC Chopper DESCRIPTION - The converter/charger shall consist of a solid-state three phase rectifier, DC to DC converter (chopper), output filter, and transient suppresser network to regulate and maintain DC power to the inverter. 1) TRANSIENT SUPPRESSER - The incoming AC utility shall first be connected to a molded case circuit breaker as a means of disconnecting power to the UPS.
2) OVERCURRENT PROTECTION - The output circuitry shall be equipped with a Hall Effect Current Transformer to detect and protect the inverter from excessively high currents. C. Static Bypass Switch 1) TRANSFER - The static bypass switch shall consist of thyristor switches in conjunction with an output contactor to permit manual switching from bypass to UPS and UPS to bypass without power interruption.
AC OUTPUT VOLTAGE (Line to Line, Line to Neutral) AC OUTPUT CURRENT BATTERY VOLTAGE BATTERY CHARGING CURRENT INPUT FREQUENCY OUTPUT FREQUENCY INPUT/ OUTPUT kW POWER FACTOR 4) SYSTEM DIAGNOSTICS - The following diagnostic information shall be provided to troubleshoot the UPS should a fault occur: UPS Ok Memory Error Wrong Phase Rotation of AC Input Internal AC Circuit Fault Internal DC Circuit Fault Heatsink Overheat DC unbalanced DC Circuit Over/Under voltage DC Circuit Overcurrent Chopper Input Overcurrent
C. Ventilation and Maintenance Requirements The UPS shall require the following minimum space for ventilation and maintenance: 28” (front), 18” (top), 6” (rear), and 0” (side). 6.0 STANDARD FEATURES A. Emergency Power Off (EPO) Emergency Power Off (EPO) terminals which trip open the UPS and battery circuit breakers. B. RS232 Communication Interface Serial data link will enable the UPS to interface with a computer to provide power status and diagnostic information. C.
B. Maintainability Calculated and demonstrated MTTR (Mean-Time-To-Repair) shall be 30 minutes including time to diagnose the problem and replace subassembly. C. Warranty The UPS system shall be provided with a comprehensive three-year onsite warranty (when purchased with a Factory-Authorized Start-up). The warranty shall cover parts, labor, travel and freight for the UPS. The battery system has a full 2 year warranty with 3 year‟s prorata total of 5 year warranty.
