below is the output power settings that can be issued by this inverter:
DC voltage and Transformer "T2" winding recommendation:
Winding Power Supply
12VDC 750W P: 24V "12-0-12" / S: 220V
1500W 24VDC P: 48V "24-0-24" / S: 220V
2250w 36VDC P: 72V "36-0-36" / S: 220V
3000w 48VDC P: 96V "48-0-48" / S: 220V
3750w 60VDC P: 120V "60-0-60" / S: 220V
4500w 72VDC P: 144V "72-0-72" / S: 220V
5250w 84VDC P: 168V "84-0-84" / S: 220V

Transformer used is the transformer CT
R1 serves to regulate the voltage to 220v inverter
R2 serves to regulate the inverter output frequency of 50 or 60 Hz (as appropriate)

This boost converter is quite useful to improve conversion efficiency, reduce output ripple, and the use of small external components. In default, the LED current is set with external sensor resistor Rset, feed back voltage is regulated to 2000 miliVolts. During the operation, the current LED can be controlled using 1-wire digital interface through CTRL pin or with PWM signal that applied to the CTRL pin through the duty cycle. It determines the feedback reference voltage. The device also has a feature of integrated open LED protection that will disable the boost converter, this is to prevent the output from exceeding the absolute maximum ratings during open LED condition.
