SECTION 16610 STATIC UNINTERRUPTIBLE POWER SUPPLY SYSTEM PART 1 GENERAL 1.1 SUMMARY This specification describes a three phase continuous duty, an on-line, solid-state, uninterruptible power system, hereinafter referred to as the UPS. The UPS shall operate utilizing the existing power distribution system to provide a high quality, reserve source of power to electronic equipment loads.
This transition shall be accomplished without any switching or coupling, and with no interruption of power to the critical load from either a failure or restoration of the utility AC power. C. Recharge - Subsequent to restoration of utility AC power, the rectifier shall automatically reactivate and provide DC power to the inverter, simultaneously recharging the system battery. This occurs automatically and without interruption to the critical load. D.
Submit a copy of factory and field test reports. 1.5 ENVIRONMENTAL CONDITIONS A. The UPS shall be capable of withstanding any combination of the following external environment conditions without mechanical damage, electrical failure or degradation of operating characteristics. 1. Operating ambient temperature: 0 degrees C to +40 degrees C (32 degrees F to 104 degrees F) no derating required. 2. Recommended operating temperature range: +20 degrees C to +30 degrees C (68 degrees F to 86 degrees F). 3.

The manufacturer shall fully and completely test the system to assure compliance with the specifications, before shipment. B. All UPS units shall come equipped with one (1) factory test report included in the UPS enclosure. The factory test report shall include the following: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13.

Power walk-in time: 10 seconds (0% to 100% load). Power factor: 1. 0.98 leading typical at 100% load. 2. 0.90 leading typical at 50% load. G. Reflected input current total harmonic distortion (THD): 1. 6% typical at 100% load. 2. 9% typical at 50% load. 2.1.4 Bypass Input A. B. C. D. 2.1.5 Nominal input voltage: 480V, 600V.
2.1.6 DC input and Battery 1. 2. Voltage: 480V DC nominal, 400V DC minimum. Voltage ripple (normal operation): less than 2% of DC voltage. A. The Battery System shall be sized to provide the specified back-up time to the inverter when the UPS is supplying 100% rated load. B. Each Battery System shall include a disconnect 600V DC circuit breaker to facilitate isolation of UPS Module DC Input and the Battery System.
input current total harmonic distortion (THD) into the utility AC input source at nominal voltage and rated load. The reflected input current shall typically not exceed 9% THD at 50 % load. C. Automatic Input Power Walk-in The rectifier logic and control circuit power walk in function enables delayed and timed ramping of input current.
following AC input restoration and subsequent to the power walk in function. This equalizing charge will occur until the battery target voltage is reached (condition is met to end equalizing charge), in which float voltage will be applied. D. Battery Temperature Compensation The UPS shall have as standard a battery temperature compensation function allowing the rectifier voltage to fold-back to a safe value in the event the battery system temperature reaches a pre determined (dangerous) level.
Input current limit setting: 110% of nominal rated current. The AC input current limit shall be set up so that the rectifier/charger can provide sufficient capacity to the inverter at rated load and have the capability to recharge a discharged battery. The input current limit protects hybrid converter components from damage due to excessive input current. 2.2.1.
within +/-5% of the nominal value. D. Voltage Transient Response The dynamic regulation and transient response shall not exceed +/-2% for 100% step load (applied or removed), +/-1% for loss or return of AC input and +/-5% for inverter to bypass and vice versa transfer. E. Transient Recovery Voltage transient response shall not exceed the above specification and shall recover to within nominal voltage regulation tolerance within 16.7 ms F.
J. Inverter Overload Protection The inverter output shall utilize the electronic inverter current limiting for protection against overload conditions (excessive overload, faults). The inverter shall utilize a contactor to isolate its output from the critical bus and the load transferred to the bypass source. The bypass static switch circuit shall be sized to provide fault clearing.
F. The UPS Module Control power supply employs a redundant design configuration, utilizing the UPS AC input (utility) and the UPS Module inverter output therefore enhancing reliability. 2.2.4 Bypass and Static Switch UPS module contains an automatic bypass static switch circuit and associated bypass static switch transfer control circuitry. A. General A bypass circuit shall be provided as an alternate source of power other than the inverter.
The static switch shall be a high speed transfer device comprised of naturally commutated SCR's. During manual transfers the static switch is not required. The static switch shall not use fuses for protection. 2.2.5 Operation/Display Panel The control panel shall employ the use of a touch screen interface which allows lock-out of all UPS control function for security (The Emergency Power Off function shall not be lock-out). The operator interface shall provide the following: 1. 2. 3. 4. 5.
