Roughly 4 decades ago, Bell Labs developed Network Equipment-Building System (NEBS) certifications to assist standardize electrical equipment in Regional Bell Operating Centers (RBOCs). As a whole, three kinds of certification were developed: Level 1, Level 2, and Level 3.
When data centers use battery-based, uninterruptible power supplies (UPSs) for emergency backup power, they might require an inverter to alter the household power (Electricity) electricity that batteries produce to alternating electric current (AC) electricity that many modern electrical equipment and appliances use. Which degree of NEBS certification is the greatest fit for any data center inverter? Below, we answer the issue by elucidating each degree of NEBS compliance.
L1 NEBS certification pertains to inverters that satisfy the personnel and equipment safety needs for GR-63-CORE and GR-1089-CORE. It does not address the operability needs of the inverter. Consequently, they’re generally employed for test purposes and therefore are rarely present in environments that provide the requirements of the finish user.
L2 NEBS certification pertains to inverters that adhere to the personnel and equipment safety needs for GR-63-CORE and GR-1089-CORE, and address operability needs on the narrow scale. The needs affect indoor operating environments that do not feature adverse conditions. Generally, the operability needs are attuned towards the general operating atmosphere of the data center that stays online night and day .
L3 NEBS certification pertains to inverters that satisfy the personnel and equipment safety needs and all sorts of operability needs for GR-63-CORE and GR-1089-CORE. It is normally present in inverters which are set up in indoor or outside environments that need the gear to function under adverse conditions, for example vibration, the existence of airborne contaminants, and weird acoustics, to mention a couple of. It’s also probably the most generally used NEBS certification.
Selecting a NEBS inverter to facilitate the whole process of an information center’s UPSs is really a guessing game, unless of course you realize what different amounts of certification are made to deliver. Because L2 certification is basically standardized to use to data center environments, NEBS L2 inverters are generally the kind of inverters that data centers implement, although L3 inverters are often used, too.
