output overvoltage protection (31.8Vdc typ. / 32.5Vdc max.)
Overload / short-circuit current -- 42A / 0A at heavy overloads (when output voltage falls below 13V) the power supply delivers continuous output current for 2s. Then the output is switched OFF for approx. 18s before a new start attempt is automatically performed. This cycle is repeated as long as the overload exists. If the overload has been cleared the device will operate normally. Load impedance 10mΩ. Discharge current of output capacitors is not included.
Over-temperature protection -- Output shutdown with automatic restart. Temperature sensors are installed on critical components inside the unit and turn the unit OFF in safety critical situations which can happen e.g. when ambient temperature is too high ventilation is obstructed or the derating requirements are not followed. There is no correlation between the operating temperature and turn-OFF temperature since this is dependent on input voltage load and installation methods.
Series / parallel operation -- not possible
Back-feeding loads max. 35V / 4J -- The unit is resistant and does not show a malfunction when a load feeds back voltage to the power supply. It does not matter whether the power supply is ON or OFF. For all 4 outputs in total

The FIEPOS Basic series offers 1 DC output and is available with a power of 300W or 500W.
The IP54; IP65 and IP67 field power supplies are perfect for the decentralized supply of 1-phase or 3-phase systems and machines.
The field power supplies can be easily connected in parallel; e.g.
to increase total performance or realize a reliable redundant system.
