POWER QUALITY GUIDEBOOK Recognize electrical disturbances. Understand their impact. Select the correct power solution.

Optimize production efficiency by eliminating power disturbances and noise. Power Quality’s Increased Importance Industrial environments depend on electronic equipment to succeed in today’s highly competitive, efficiency-driven business world. Computers, drives, motion controllers and sensors have become essential for optimal productivity, consistency and quality. However, these sensitive components require clean and stable electrical quality to perform properly. Power quality issues, such as voltage fluctuations, harmonic distortions, noise and power outages, disrupt production, damage equipment...

Recognize electrical disturbances. Understand their impact. Select the correct power solution. VOLTAGE SURGE A voltage surge, also referred to as an overvoltage or a line swell, is a temporary voltage level increase for durations from a half cycle to a few seconds. These disturbances can also last as long as several cycles. Voltage surges can be caused by large load shut-downs, such as switching off high-power electric motors and the normal cycling of HVAC systems. They can also be caused externally as loads are shed from the utility. POWER INTERRUPTIONS Power interruptions are a complete loss...

Surges and swells can lead to significant equipment and hardware damages. UPS Power Conditioners* Voltage Regulators SolatronTM Plus Power Conditioner Power interruptions halt production and can decrease the lifespan of electrical equipment. The sudden nature of most power interruptions can also create hardware failures and crashes in PLCs and other computer-based equipment. Brownouts can negatively impact the efficiency and lifespan of electrical equipment. They can also result in hardware crashes and occasional equipment failure. Voltage Regulators* Similar to voltage reductions, repeated exposure...

Recognize electrical disturbances. Understand their impact. Select the correct power solution. VOLTAGE TRANSIENTS Voltage transients, also called spikes and impulses, are the result of sudden massive increases in voltage. FREQUENCY VARIATIONS While rare in utility power, frequency variations are most common with back-up power systems, such as standby generators. HARMONIC DISTORTION Voltage distortion is created by multiples of the fundamental frequency (for example, 180 Hz in a 60 Hz system). ELECTRICAL NOISE Electrical noise is a low amplitude, low current, high-frequency disturbance. POWE R...

Sensitive electronic equipment is most at risk from these disruptions. A voltage transient may cause system lock-up or failure, which can corrupt or lead to loss of valuable data. Surge Protective Devices* Power Conditioners Isolation Transformers Surge Protective Devices Frequency variations can cause system crashes and equipment damage, even ones that have UPS protection. Harmonics represent trouble for equipment throughout industrial facilities by overheating neutral conductors and transformers, tripping breakers, creating a high neutral current, reducing system capacities and even loosening...

ACTIVE TRACKING® FILTERS & SURGE PROTECTIVE DEVICES Today’s industries depend on their production, computing, networking and telecommunication equipment for optimal manufacturing performance. SolaHD’s surge protective and filtering devices protect these critical operations across facilities from the continuous threat of voltage transients and electrical noise. The STV 100/400K series consists of hardwired surge protective devices and the STV 25K is a DIN Rail mountable surge protective device. Installed in electronic control cabinets, they both can be found in harsh industrial environments such...

POWER CONDITIONERS Power conditioners hold output voltages steady relative to the wide swings in input voltage. They also mitigate noise and other disturbances generated throughout the facility. SolaHD’s power conditioners ensure that the power reaching your equipment is free from damaging voltage transients, voltage reductions, sags, surges, harmonics and noise. Constant Voltage Transformers Hardwired CVS Series SOLATRON™ Plus Three Phase Power Conditioner Constant Voltage Transformers are excellent for industrial applications requiring tight voltage regulation. Using a ferroresonant transformer...

UNINTERRUPTIBLE POWER SUPPLIES - Off-LinE SolaHD's Off-line Uninterruptible Power Supplies (UPS) provide economical protection from damaging impulses and power interruptions for smaller, less critical, stand-alone applications. They are ideal for computers and workstations that can tolerate the 2 – 4 milliseconds of transfer time when the UPS switches from AC input to battery power. SolaHD has UPS systems that protect your equipment from all power disturbances. SDU AC DIN Rail UPS The SDU DIN Rail AC UPS combines an industry leading compact design with a wide operation temperature range and unique...
