1-1-1 Power-Reg and Ultra-Reg
The Power-Reg and Ultra-Reg are designed to provide the reliable, high-quality power necessary to meet the
needs of today’s sensitive electronics.
These three-phase, 60 Hertz, self-contained, modular units provide isolation 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. And also single phase, 60Hz, self contained units are
available.
The Power-Reg and Ultra-Reg are available in input voltages of 208 or 480 VAC and output voltages of
208Y/120 and 480Y/277 VAC. These units are available in sizes ranging from 15 kVA to 400 kVA. The specific
rating information for your unit is provided on the label plate located on the front panel. Refer to Appendix A.
The Power-Reg and Ultra-Reg unit is shown in Illustration 1-2.
