Telecommunication Specialized DTS Series
Description：
DTS series is an electrical dedicated inversion power supply,
Powerstar designs a telecommunication industry classes inverter
power supply production. The system adopts the non-master-slave
parallel multistage decentralized control technology which has
features like non-operation bottleneck and reliable function. DTS
is comprised of the static switch module, system machine cabinet,
system monitoring unit and 1 to 36 power modules (optional 4850
rectifier) in parallel and also include the standard manual
maintenance switch, OBO lightning protection module, RS232/RS485
communication interface and host computer monitoring software. Its
capacities have 36KVA, 72KVA, 108KVA three series. The power module
is 3KVA that the users can random choose according to the carried
loads condition. The users can set randomly the 3 / 1 or 3 / 3
in-out wire mode and N + X redundancy. It is based on the actual
demand to upgrade the expansion on line. According to the
telecommunication industry's existing resources and higher
standard, all the power modules adopt the hot plug mode to random
expand, replace and share the battery units. They also have the
internal AC isolation transformer to isolate the external impact
caused the possible damage for the UPS system or the loads. When we
select the original components of the UPS we choose the high
quality components with strict test program which suit for the
telecommunication industrial requirements to ensure the
products'stability and reliability.
(1)Static Switch Module
Static Switch Module is mainly used for quick switch between the
inverter's output and the AC bypass power supply to completely
enhance the system power supply Safety and reliability.
They receive two groups AC input, when they choose one group output
in the online conditions the Static Switches are going to connect
the power module inverter output to the system output, if the power
module can't provide the enough voltage at a particular time the
static switch will immediately switch to the bypass power supply.
The static switch adopts the mixed type control technology which is
the parallel high-performance AC switch, consisted of the rapid
semiconductor devices (controlled silicon) and the electromagnetic
contactor, it solves the switching time problem and also enhances
the anti-impact ability and anti short-circuit ability of the
static switch to greatly improve the system's reliability and
stability.
The inside of static switch have self-test function, interlock
function, system output fault protection function, instantaneous
power-off protection function, output overload and short-circuit
protection function etc. It also has the RS485 communication
function that can communicate with system monitoring to send and
receive operation orders and various alerts information at any
time.
(2)System Monitoring Module
System Monitor is located in the top of the machine cabinet,
through the display and the operation panel the users can easily
understand the system's working status, parameters'inquiry and all
kinds of event information. After the system is installed the users
can finish the all operations for the system by the monitoring
operation panel.
System Monitoring completes the data collecting system by a
dual-core 16-bit processor. The monitor adopts the 128240 VDF
technology to display clearly, it has a 5-button operation menu
mode to do the simple and flexible operations.
It Offers RS232, RS422 and RS485 communication interface and the
multi-path dry contact output. System Monitor is divided into three
regions: status indicator area, data information display area,
keypad operating area. The status indicator area provides the
simple system status information for the users by the different
states display of LED; the data information display area provides
the detailed system status information The system monitoring
display: system data (Data), main interface (Graphic), records of
historical events (Events), function settings (Setup) four friendly
operation interfaces. The keypad oper
