Does your laboratory suffer from regular power outages, or are you finding that critical components are failing prematurely? Did you know that the issue could be with your power supply rather than your instrument? Below we detail the 10 most common power problems you may have in your laboratory.
AC Blackout is a total loss of utility power occurring for more than 2 cycles.
Power Sage refers to a short-term low voltage caused by large equipment starting inrush current, utility switching, or a temporary overload.
Voltage surge is a short-term high voltage above 110% of nominal for several cycles.
Brownout refers to a long-term reduced line voltage for an extended period lasting a few minutes to a few days.
Overvoltage is an Extended period of increased line voltage ranging from a few minutes to a few days.
Normal mode noise is a high-frequency electrical waveform between line (L) and neutral (N) caused by RFI or EMI interference.
Frequency change from nominal 60Hz or 50Hz. Operation from engine generators can produce frequency variations.
Switching transient is a fast high voltage spike with a very short duration time.
Distortion of the normal waveform is generally caused by nonlinear loads such as rectifiers, switch-mode power supplies, and variable frequency drives.
Common mode noise is electrical interference measured between ground and either neutral (N) or line (L) of a typical AC power line.
Isolated Online UPS, also known as Power Conditioned Online UPS or Laboratory Grade UPS, protects against all 10 of the common power problems. This premium technology adds galvanic isolation transformer to the online UPS topology protecting from common mode noise. Isolated Online UPS are used to provide the cleanest power under challenging applications such as industrial environments, laboratories, retail, and any installation with grounding or noise issues.
