Three Phase UPS Systems
1. SYSTEM OVERVIEW
1-7
(n) Intelligent battery test: The batteries are tested after every boost (initiated
by battery discharge or by the monthly boost charge cycle). This is done without
interrupting the operation of the rectifier, preventing the risk of output AC
failure in case of a bad battery. The user is informed of the battery condition, so
that action can be taken before the full capacity of the batteries is needed.
(o) Selectable charging power: The charging power is selectable
(Lo/Me/Hi) according to A/H rating of the batteries, and can charge up
battery banks providing more than 8Hrs back-up time without adding an extra
charger.
(p) Long life fans: The fans used to cool the UPS are designed to slow down under
light load, so that the life expectancy of the fans is extended beyond the normal.
(q) Redundant power supply: A supplemental power supply is added to provide
redundancy for supplying power to the static switch; assuring there will be AC
output regardless of any internal failure.
(r) Variety of Communication ports: With built-in intelligent
communication interface as well as output ports of RS-232, RS-485 and dry
contacts, there are several options available. These options include remote
control panel, 3 phases software for PC monitoring, auto dialing module, battery
monitoring module, 3 phases SNMP card, and emergency power off (EPO) switch.
Please refer to the chapter 7 option details.
