PC Power Supply with Resin Panel
 eNSP-300P-S20-00S Easy Grade-up to Nonstop Power Supply (with UPS function)! Starting with regular ATX power supply first to keep implementation cost low, install the optional Nonstop Unit (BU-300P-24P) to meet the backup requirement (against power failure) in case you need it later on.

•Nonstop unit and signal unit can be added to obtain backup function.
•Peak 300W output with 12V connector
•Power Factor 98% with Active Filter (PFC)
•Very Quiet with thermo-sensing speed control FAN
