1-2 BENEFITS
The Power-Reg, Ultra-Reg, Phase Stabilizer and CP 18 protect electronic equipment from an overvoltage
condition during line power surges and an undervoltage condition during sags. In addition, the unit protects
equipment load by attenuating transients present on utility power lines. overvoltage, overcurrent, and transient
conditions stress electronic components and decrease system reliability.
In medical applications, voltage fluctuations affect the image quality of imaging systems. Artifacts are
introduced under sag conditions. Regulating power maintains image quality, resulting in more consistent
images.
1-3 TRANSFORMER
The transformer contained in the unit is designed for convection cooling by means of free circulation of air
through the bottom, front and back of the unit. Maximum ambient temperatures should not exceed 104°F
(40°C). The transformer contains built-in thermal sensors which monitor internal temperatures. In models with
a Input Main Circuit breaker (IMCB), the thermal sensors send a shunt trip signal to the IMCB in the event of an
over temperature condition.
