Photovoltaic power generation system has the following requirements for module power supply:
1. 200-1200VDC voltage input,
2. output 12V/15V/24V and other conventional voltage
3. the input and output can withstand high isolation voltage characteristic
4. equipped with input under-voltage protection,
5. anti-reverse connection protection, output over-current protection,
6. short-circuit protection and over-voltage protection.
To meet the extreme working temperature difference requirements in different regions, for the high voltage characteristics and application requirements of photovoltaic power generation system.
CHONDA specially developed a 200-1200VDC voltage input, 4000VAC isolated module power supply, and combined with the photovoltaic system each unit circuit safety isolation characteristics, to provide a set of control unit power supply scheme.
