Our Masterguard Online UPS series have two types, standard machine with built-in Batteries (Model suffix with “S”) and long run machine (Model suffix with “L”).
For example, MGT-10KS, “MG” means MasterGuard Series, “T means three phase and “10K” stands for 10KVA, Suffix “S” means Standard Machine with built-in Batteries.
Standard UPS is with the built-in backup batteries which allows you to save/back up your data and shut down your sensitive electronic devices safely and/or avoid downtime altogether.
However, the typical backup time is about 5 to 15 minutes, so it cannot withstand a prolonged power outage. The UPS should be used for safe shutdown of the system and as a connection until the generator starts up.


Long run effective UPS provides you with extended backup time from 30 mins to 4 hours or longer, long run models are connected with optional External Battery Cabinet (EBC) as below.
External Battery Cabinet Example
No matter what type of UPS system you buy, you’ll need to make sure it has enough capacity to support the wattage of the devices you plug into it, as well as enough battery runtime to shut down safely. 
Simply tally up the wattage of every device you plan to connect your UPS to (this is your load) and multiply that number by 1.25 to determine the UPS capacity you need. Your load should not exceed 75%-80% of your UPS system’s capacity. 
However, for the load with motor or the compressor, due to the initial startup current is around 5-6 times of the rated, so you need approximately 5-6 times of rated power capacity when choose the UPS.
