| LH SERIES UPS SYSTEMS : True Online Double Conversion Intelligent Sinewave Long Backup (no internal batteries) 700VA - 3000VA Click on the pictures below to view full specifications on the UPS system |
 |
|||
|
The LH Series UPS is an advanced true on-line, double conversion UPS system which is suitable for larger battery banks to provide longer back-up times. It is Intelligent Microprocessor controlled. Generator compatibility is one important advantage for certain power supply conditions and RS232 communication advanced design make it compatible for sophisticated monitoring software. The 2KVA and 3KVA models have better power security through 'Redundant' features and also have an internal SNMP slot option.
