Remote Sense

Compensates for 0.5 V max voltage drop, if remote sense is not required, local sense must be used

Enable

Output must be enabled, see application notes, power supply is shipped with enable links fitted

Current Share

5 supplies can share within 5%

Standby Output

5 V at 0.5 A, present whenever AC is applied (9 V at 0.3 A, user selectable, by connecting ‘VSET’, Pin 18 of CN2 to GND)
