ML15.051

MiniLine-2

5V, 3A, SINGLE PHASE INPUT

21.3. EXTERNAL INPUT PROTECTION

The unit is tested and approved for branch circuits up to 20A. An external protection is only required, if the supplying

branch has an ampacity greater than this. Check also local codes and local requirements. In some countries local

regulations might apply.

If an external fuse is necessary or utilized, minimum requirements need to be considered to avoid nuisance tripping of

the circuit breaker. A minimum value of 6A B- or 3A C-Characteristic breaker should be used.

21.4. PARALLEL USE TO INCREASE OUTPUT POWER

ML15.051 power supplies can be paralleled to increase the output power. This

power supply has no feature included which balances the load current

between the power supplies. Usually the power supply with the higher

adjusted output voltage draws current until it goes into current limitation. This

means no harm to this power supply as long as the ambient temperature stays

below 45°C. The ML15.051 can also be paralleled with power supplies from

MiniLine series with 5V output voltage. The output voltages of all power

supplies shall be adjusted to the same value (±100mV). A fuse or diode on the

output of each unit is only required if more than three units are connected in parallel. If a fuse (or circuit breaker) is

used, choose one with approximately 150% of the rated output current of one power supply. Keep an installation

clearance of 15mm (left / right) between two power supplies and avoid installing the power supplies on top of each

other. Do not use power supplies in parallel in mounting orientations other than the standard mounting orientation

(input terminals on the bottom and output terminals on top of the unit). Pay attention that leakage current, EMI,

inrush current, harmonics will increase when using multiple power supplies.
