Product Description

The ST-3KW Series is a new expandable and customizable pure sine wave inverter ,

designed specifically for 19-inch rack-mounted applications in the communication field.

Housed in a 4RU 19-inch rack chassis, it features a new-generation dual-input solution with 220V AC

and 12V DC power inputs.

This fills the gap between traditional UPS power supplies and common pure sine wave inverters,

providing a highly reliable power source for critical communication loads.

Equipped with double CPU intelligent control technology, it offers excellent performance.

The inverter has multiple operating modes such as grid mode, energy-saving mode, and

battery mode, providing flexible application scenarios. It has an RS232 communication port

for easy connection to monitoring systems. The LCD display shows real-time equipment parameters

and operation status clearly.

The unit comes with a series of protective features including short load protection, overload protection,

battery over/under voltage protection, overcurrent protection, and over-temperature protection.

It also has a maintenance bypass and DC backup option. The pure sine wave output (T.H.D < 3%) ensures

stable and high-quality AC power supply, and the seamless conversion between AC and DC power sources,

with a switch time of less than 6ms, is achieved through a built-in static switch.

Main features:

 Standard 19” Rack mount 4RU Chassis;

 True sine wave output (T.H.D < 3%);

 LCD display equipment parameter in real-time, operation status be

 clear at a glance;

 Double CPU intelligent control technology, excellent performance;

 The grid mode/energy-saving mode/battery mode could be set, application flexible;

 RS232 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 6ms;

 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
