output overvoltage protection (30.5Vdc typ. / 32Vdc max.)
NTC (input inrush current limiter)
Overload / short-circuit current -- 27.5A continuous current / 30A typ. intermitted current peak value for typ. 1s. Load impedance 50mΩ. Discharge current of output capacitors is not included. / Max. 11A intermitted current average value (R.M.S.) Load impedance 50mΩ
Series / parallel operation -- Buffer units can be added in parallel to increase the output ampacity or the hold-up time. Power supplies can be paralleled for redundancy to gain higher system availability. Redundant systems require a certain amount of extra power to support the load in case 1 power supply unit fails. The simplest way is to put 2 power supplies in parallel. This is called a 1+1 redundancy. In case 1 power supply unit fails the other 1 is automatically able to support the load current without any interruption
Back-feeding loads max. 35V -- The unit is resistant and does not show malfunctioning when a load feeds back voltage to the power supply. It does not matter whether the power supply is ON or OFF. The absorbing energy can be calculated according to the built-in large sized output capacitor.
