Output voltage external control function is available. Output voltage can be varied by applying an external voltage (3-6V) to ‘PV’ and ‘COM’ terminals at
signal connector CN1
Please consider the following characteristics.
Notes:
For 12V & 36V output model, limit output voltage variation range at 60% - 110%. At PV voltage variation 3V - 5.5V
For 24V output model, limit output voltage variation range at 60% - 120%. At PV voltage variation 3V - 6V
For 48V output model, limit output voltage variation range at 80% - 120%. At PV voltage variation 4V - 6V

Provide clearance 15mm or more on top of power supply
Mounting Method
1 This is convection cooling type power supply. In consideration of the heat radiation and safety, please keep a distance of more than 15mm between the power supply and the peripheral
parts. When lining up multiple units, please make sure to place them 5mm or more apart from each other
2 Maximum allowable penetration of mounting screws into the power-supply is 5mm
3 Recommended torque for mounting screws (M4): 1.27 Nm (13.0 kgf.cm)
