The humidity in the computer room has changed from about 50% down to 35% Relative Humidity (RH).
What influence does this have on Electrostatic Discharge (ESD)?
A customer requires THDi from the UPS not to exceed 3% and wants high efficiency. The UPS has a 6-pulse SCR/thyristor rectifier and is loaded ~80%. Many ICT changes are expected in the next 3 years. What should you recommend?
The location of a data center is just above the Arctic Circle (North Pole). The outside air temperature is never above 21°C/70°
F.
Taking energy efficiency as the highest priority, which cooling system should you recommend?
A data center requires an audit to find out whether it conforms with ANSI/TIA-942 Rated-3 (concurrently maintainable).
Will the network architecture be part of this audit?
Management requests a 15-minute battery bank at full UPS load. UPS specs:
30 kVA, PF 0.8
Battery 384 V (192 cells), end discharge 308 V
Inverter PF 0.8, 400 V output
What information is missing to perform the calculation?
You are changing the design of the fire suppression system for your computer room from a halocarbon fire suppression system into an inert-based fire suppression system. Could you use the same formula to calculate the gas content for the gas?
