Constant Power 18
The Constant Power 18 is designed to provide the reliable, high-quality power necessary to suit the needs of
today’s sensitive electronics.
This three-phase, 60 Hertz, self-contained, modular unit provides isolation, shielding and regulation of AC
power. The zero-current tap switching voltage regulation circuitry automatically adjusts for an input voltage
range between +10% surge and -26% sag about the nominal rated voltage with an output voltage range of ±
3% typical to ± 4% maximum. Each phase is regulated independently.
The Constant Power 18 is available in input voltages of 208 or 480 VAC and output voltages of 208Y/120 and
480Y/277 VAC. These units are available in 15, 30, 50, 75, and 100 kVA capacities. The specific rating
information for your unit is provided on the label plate located inside small front door. Refer to Appendix A-3.
The Constant Power 18 is shown in Illustration 1-3.
