General information 1. General information 1.1 Application and advantages 1.1.1 Application 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...

General information 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. 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, 10A => dV = 1.2 V Setting for Pb battery charging: 27.6...

Technical information 2. Technical information 2.1 Description of functions 2.1.1 Protections ● ● 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. 2.1.2 Power derating The DBC-1 series has a high temperature...

Technical information Inom Imax 2.1.4 Charger Failure Alarm These units have a dry contact alarm output which is closed (energised) under normal operating conditions (no failure). The alarm contact is steady open when: ● Failure on the line input or input fuse ● No output voltage. 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) 2.1.5 LED...

Technical information Alarm functions The LED will be steady red when: ● Failure on the line input or input fuse ● No output voltage. The LED will flash between red and green when: ● Failure caused by battery reverse polarity connection ● Overvoltage condition on output terminals. Boost-charge indicator The LED indicator will turn blue when the boost-charge mode is activated. Input power OK The LED indicator will be steady green when there is healthy voltage on the output terminals. 2.1.6 Equalisation/boost-charging Equalisation is activated by making a short circuit between the terminals...

Technical information 2.2 Technical specifications 2.2.1 General data Duty ratio Continuous duty is allowed Protected against continuous short-circuit No-load operation Protected against continuous no-load operation DIN-rail, EN 50022-35 or 4 pcs. Ø4.5 mm holes for screw mounting.To obtain optimum cooling, it is imperative to comply with the specified installation position, where the terminals are at the bottom. If the mounting differs from this, a reduction in output must be expected, depending on the ambient temperature. If placed in conditions with vibrations, it might be necessary to...
