CPS20.481-D1

C-Series

48V, 10A, DC/DC CONVERTER

22.7. SERIES OPERATION

DC/DC converters of the same type can be connected in series for higher

output voltages. It is possible to connect as many units in series as needed,

providing the sum of the output voltage does not exceed 150Vdc. Voltages

with a potential above 60Vdc are not SELV any more and can be dangerous.

Such voltages must be installed with a protection against touching.

23/25

Earthing of the output is required when the sum of the output voltage is

above 60Vdc.

Avoid return voltage (e.g. from a decelerating motor or battery) which is

applied to the output terminals.

Keep an installation clearance of 15mm (left / right) between two DC/DC

converters and avoid installing the DC/DC converters on top of each other. Do not use DC/DC converters in series in

mounting orientations other than the standard mounting orientation (terminals on bottom of the unit).

Pay attention that EMI and inrush current will increase when using multiple DC/DC converters.

22.8. INDUCTIVE AND CAPACITIVE LOADS

The unit is designed to supply any kind of loads, including capacitive and inductive loads. If extreme large capacitors,

such as EDLCs (electric double layer capacitors or “UltraCaps”) with a capacitance > 0.15F are connected to the output,

the unit might charge the capacitor in the Hiccup

PLUS

mode (see chapter 6).
