EXPLANATION UPS TYPE:

ISZBN  AAA/aaa – BBB/bbb – 1f(or 3f)/ccc – ddd
– AAA/aaa  (rectifier voltage / rectifier current)
– BBB/bbb (output voltage DC/DC converters / output current)
– 1f or 3f / ccc (output one phase or three phase / output power kVA
– ddd (battery capacity C10)
For example, ISZBN 220/100 – 48/40 – 1f/7.5k – 200 
Values: rectifiers, output 220 VDC – 100 A , 
+ DC/DC converters 220 VDC / 48 VDC – 40 A  
+  DC/AC inverters 220 VDC / 230 V,50 Hz  
– output power 7.5 kVA 
+  battery 220 VDC – C10 = 200 Ah
– the customer needs to define:  input voltage, output voltages, output power,
autonomy and specification of output switches
