1-1-2 Phase Stabilizer
The medical-grade Phase Stabilizer power conditioner is designed to provide the reliable, high-quality power
necessary to suit the needs of today’s sensitive medical devices.
This three-phase, 60 Hertz, self-contained, modular unit provides isolation and regulation of AC power. The
zero-current tap switching voltage regulation circuitry automatically adjusts for an input voltage range between
+8% surge and -10% sag about the nominal rated voltage with an output voltage range of ± 1.5% typical to ±
2% maximum. Each phase is regulated independently.
The Phase Stabilizer is available in input voltages of 208 or 480 VAC and output voltages of 208Y/120 and
480Y/277 VAC. This unit is 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 15 to 100 kVA Phase Stabilizer with 480 VAC or the 15-75 kVA with 208 VAC is shown in Illustration 1-3.
The 125 to 400 kVA Phase Stabilizer with 480 VAC input or the 100-400 kVA with 208 VAC input is shown in
Illustration 1-2.
