ATX power supply with a built-in lithium-ion battery
 HNSP5-350P-S20-B1V More space can be saved because of the battery package in a housing
Double-sided through hole PCB suitable for industrial use.
Achieved low noise and low leakage current
Min. load current is 0A for all outputs.
By building in the thermal-sensing variable speed fan, noise reduction can be realised.
Signal for shutdown control by RS232C
