Medical standard approved, Low Power Consumption and High Efficiency SFX Power Supply !

Medical standard approved, Low Power Consumption and High Efficiency SFX Power Supply !

Medical standard IEC60601-1 3rd(MOOP) approved
Double-sided through hole PCB suitable for industrial use.
High efficiency with synchronous rectification circuitCompletely independent voltage-stabilizing circuit is mounted for all outputs. Min. load current is 0A for all outputs.
Safety standard approved (IEC/UL/CSA/CCC)By building in the thermal-sensing variable speed fan, noise reduction can be realised.
Heat-related issue for CPU can be settled with fan speed changeover switch.
