DATA SHEET DBC-1 DEIF Battery Charger

Overvoltage protected Boost/equalisation functionality Failure alarm functionality DC supply The DBC-1 can be used as DC supply due to the low ripple of maximum 1.3 %. Automatic recovery and protection against overload, short circuit and reverse polarity are standard functionalities of the DBC-1. Battery charger DBC-1 is ideal for the use as battery charger. The general recommendation for charging lead (Pb) batteries is a voltage ripple of maximum 2-5 %, where the maximum voltage ripple for DBC-1 is 1.3 %. It is designed to charge both lead-acid and gel batteries. The recommended charge...

Voltage drop The charger can be adjusted to compensate the voltage drop in the wiring between the battery and the charger. Please notice that the current is only 50 % of the nominal current if the boost/equalisation function is used. Examples of voltage drop can be found in the table below. Example of DC voltage drop Wire size, mm2 * Based on threaded copper wire at 20°C. The voltage drop formula is: dV = length x current x cable resistance x 2, thus the double current or double length will also double the voltage drop. Example: 1.5 mm2, 5 m, 10 A => dV = 1.2 V Setting for Pb battery...

Protected against continuous short-circuit and no-load operation Protected against reverse battery polarity connection, and automatically restarts operation after the fault is removed Protected against over-temperature Protected against undervoltage on line input Protected against overvoltage on output. The unit shuts itself down when an overvoltage on output terminals arises. An alarm condition occurs in any of the above cases. Power derating The DBC-1 series has a high temperature protection designed to allow safe operation at all times. The power output derates above 60°C of ambient...

The alarm contact is steady open when: • Failure on the line input or input fuse The alarm contact will work intermittent when: • Failure caused by battery reverse polarity connection Overvoltage condition on output terminals. (Note: when overvoltage is detected while battery is connected, the alarm relay is open and locked in this position until the battery is disconnected) LED indication and alarm relay status Alarm relay Normal operation Short circuit on output Reverse polarity connection Switching open/closed *) High temperature/power derating No input voltage with battery connected No...

Equalisation is activated by making a short circuit between the terminals "minus" and "boost". When the equalisation is activated, the output voltage is increased by 0.8 V DC at 12 V versions and 1.6 V DC at 24 V versions. The current will be reduced by approx. 50 %. Inom Imax INFO Equalisation is only for lead-acid batteries and not acceptable for gel type batteries. Please check the battery manufacturer specifications for equalisation charge. Technical specifications General data Duty ratio Continuous duty is allowed Protected against continuous short-circuit No-load operation Protected...
