Uninterruptible Power Supplies shows you how to conquer threats posed by brownouts and blackouts and protect today's sophisticated and expensive electronics
In Uninterruptible Power Supplies you can find complete, up-to-date guidance on design, installation, operation, and maintenance.
As a twenty-first century engineer, you're being asked to guard sensitive, costly electronic equipment against the increasing dangers of rolling brownouts and blackouts, surges, sags, spikes, noise, and power failures, as well as the omnipresent hazards of lightning-induced transients.
Uninterruptible Power Supplies gives you thorough guidance on up-to-date methods and products.
Inside, you'll find what you want to--
- Design, install, maintain, and operate fail-safe systems with standby generators, chemical batteries, kinetic energy systems, with either static or rotary UPS sets
- Apply complete, system-wide design examples
- Deliver full protection from faults originating in electric utilities and all forms of dangerous power anomalies
- Support every type of load, including excursions outside normal tolerances in both power factor and harmonics
- Get realistic solutions in line with power quality issues, markets, and cost factors
- Select the right batteries, using the latest product information and criteria
- Troubleshoot standby system problems
