SD1500 Series 1500W Pure Sine Wave

Product Information:

The SD1500 series is a 1500W pure sine wave power inverter
designed for multiple industrial applications. It features a
parallel redundancy design for power expansion, automatic master
mechanism to eliminate single point failure, and built-in ATS and
AC circuit breaker. The optional STS module allows for transfer
time of less than 4ms. The inverter also offers RS-232
communication and input/output isolation. It has selectable output
voltage/power saving mode and can be controlled remotely using the
CR-10 remote control.

Product Usage Instructions:

To use the SD1500 series power inverter, follow these steps:

Ensure that the input DC voltage matches the requirements of
your system. The SD1500 series is available in different models
with different input voltages (12VDC, 24VDC, 48VDC).
Connect the DC input to your power source within the specified
voltage range. Make sure the polarity is correct to avoid reverse
polarity damage (fuse protection is provided).
Connect the AC input to the desired load or utility power
source.
Ensure that the output voltage and power saving mode are set
according to your requirements. This can be done using the DIP
switch on the inverter or using the remote control (CR-10).
If necessary, install the optional STS module for faster
transfer time between utility AC and inverter power.
Make sure the output load does not exceed the maximum rating
power, and avoid short circuits, overload, over temperature, and
overvoltage conditions to ensure proper output protection.

Note: The SD1500 series power inverter has a total harmonic
distortion (THD) of less than 3% under specific conditions. It
operates at an efficiency of up to 90% and provides a pure sine
wave output.
