The pure sine wave DT-1000 Series inverters are BWITT new expand
customize inverter. This Series is a professional 19” rack
enclosure with a
wide range of options to suit applications.
Description:
This type Rack mount Inverter with a new generation of dual input
inverter solution
designed for the field of communication applications, which is
suitable for the high
reliability of the communication system. The solution is equipped
with 230V AC power
supply and 24V DC power Input , which fills the gap between the
traditional UPS power
supply and common pure sine wave inverter solutions.
It uses a novel design structure that helps users to provide Pure,
stable and durable AC
power for critical loads, and has the same high reliability as the
AC power supply system.
The design characteristics of the dedicated communication pure sine
wave inverter ensure
the seamless conversion between the AC and DC power supply, almost
no conversion
delay, and build in the static switch.
Main features:
Standard 19” Rack mount2 RU Chassis;
True sine wave output (T.H.D < 3%)；
Large 128*64 digital Lcd display data information,4 led display
working;
5 Routes Dry contact for system (DC input fault, AC input fault,
overload
information, by-pass information and output fault)；
RS232 and RS485 & Optional SNMP communication Port；
Power-on self-test, Soft output start,Start auto restart while Ac
or Dc is recovering;
Auto switch function: DC to AC, AC bypass, less than 5ms;
Real-time monitoring of the system operating status,Audible and
visual alarm;
Record the historical alarm message and can be queried;
Build in voltage regulator Stabilize AC voltage;
Maintenance bypass /DC available;
Protection :Short load protection, over load protection, battery
over/under voltage
protection, over current, over temperature;
Application:
All business critical applications and all types of AC loads.
The design is modular and scalable with hot- swappable
inverter modules which ensures low Mean Time to Repair
reduction in service costs and meets the changing
needs for future expansion.
