Under normal conditions, the 78 Series Power Supply supplies the current required by the load. 

However, under abnormal conditions such as a short circuit or heavy overload (T0) the output voltage will be rapidly reduced to zero - followed by the current (T1). After approximately 2 seconds (T1 to T2), the power supply checks for the persistence of the anomaly over the time period T2 to T3 (30 to 100ms - dependent on the type of anomaly). If the anomaly persists, as shown above, the current is again reset to 0 A for a further 2 s (T3 to T4). This “hiccup” process is repeated until the anomaly is removed (Tn), whereon the power supply then returns to normal working. 

78.1B is able to handle this anomaly for 15 s. After this time it enters in protection mode, and a manual reset is necessary by removing and re-applying the supply voltage

## **Fold-back technology and battery charging** 

**Fold-back technology** allows load current to be maintained under conditions of heavy overload. In case of heavy overload, the fold-back circuit will provide the output current and the output voltage, in accordance with the relevant "FB" diagram. In practice, when overcurrent is drawn by the load, the fold-back circuit reduces the output voltage supplying the current up to the maximal value, then it starts to work in hiccup mode. Also in case of short circuit, the power supply will work in hiccup mode. Both these conditions end when the anomaly is removed, and the power supply returns to normal working. 

The fold-back mode allows the use of the power supply as a **battery charger,** in particular 78.50/60 for charging lead acid batteries (both standard and gel types) rated 7…24 Ah and 78.1D for charging lead batteries rated 17…38 Ah. In any case, it is necessary to verify that the charging characteristics of the batteries are compliant with the output characteristics of the power supply. 

It is suggested to insert a diode in series between the + output and the + input of the battery (if not already installed in the battery unit). 

## **Back-up connection for mains interruption** 

When the mains is ON, the power supply is able to charge the battery and supply the load at the same time (the power supply must be rated minimum 110 % of the load).  When the mains is OFF, the battery starts to supply the load.
