Uninterruptible Power Supply
p. UPS Output Fuse: When the UPS is overloaded, the fuse will open.
q. UPS Output EMI Filter: To eliminate the magnetic interference from the UPS Output and avoid the interference
caused by the output load and the UPS.
r. CAM Switch(Maintenance Bypass Switch): Through this switch, the output load can be supplied by Bypass
Source, so a routine maintenance job can be proceeded without interruption of the systems connected to the
output.
s. UPS Isolation Transformer:
t. Communication: RS232 serial port & RJ45 parallel port with CAN technology.
u. Optional Slots: for variety use of interfaces provided such as SNMP card, 2nd RS232, USB, Relay Contact Board,
etc.
v. Optional Interface Boards: WEB/SNMP card, Dry Contact Board, RS485 card, USB card, 2nd RS232 card, etc.
w. Remote Control Box: To provide remote monitoring and control functions.
