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.
