Online ups 110v output factory1/1/2024 In addition, there are also components such as an External Maintenance Bypass, which enables the UPS to be removed and/or replaced without interrupting the load, Transient Volt Surge Suppressors (TVSS), and Simple Network Management Protocol (SNMP)-compliant monitoring and communications applications. Having to transfer to mains supply isn’t ideal as the power won’t be filtered or conditioned as usual in an online double-conversion UPS, but it does enable equipment to continue functioning while the UPS is repaired or replaced.ĭepending on the size and type of UPS, there are several other common components that may be included, for example, fans or capacitors. In the event of a UPS fault, the static bypass switch automatically connects the load to the mains supply, bypassing the rectifier, batteries, and inverter. This component is a safeguard in case there’s a failure within the UPS system. This conversion process (AC to DC to AC) and filtering smooths out events such as spikes, sags, surges, and electrical noise, ensuring the final output is a pure sine waveform. This component fulfils the second half of the double conversion by switching the DC voltage from the rectifier or battery back to an AC output that powers the critical load. Whereas in larger solutions, UPS batteries are often housed in their own standalone cabinets. ![]() Batteries within a string are connected in series, so if a single battery fails, so too does the entire string.įor smaller UPS systems, the batteries are often internal to the unit. UPS battery systems have at least one string of batteries, with the number of batteries required depending on the DC voltage of the UPS. Either the rectifier or a separate charger ensures that the batteries are always charged. The batteries in a UPS system provide emergency power when the mains supply fails. UPS rectifiers can accept wide input voltage fluctuations, meaning the system can handle overloads or surges without having to engage the batteries. below 3 kVA) it is not uncommon for the rectifier and battery charger to be separate components. With smaller uninterruptible power supply systems (i.e. Its second main role is to recharge the batteries, while the DC power routes to the inverter too.ĭepending on the size of the UPS, the rectifier module may incorporate the battery charger. The first is to convert the input power from AC (Alternating Current) to DC (Direct Current). The rectifier carries out several key functions. There are four main components in any online double conversion uninterruptible power supply (UPS) system: Rectifier UPS Batteries Inverter and Static Bypass Switch.
