Page 6: Product Function
The BCDC2420(-LV) is a three-stage, 24 V DC-DC battery charger that operates from an alternator input of 12 V nominal or a 12 V nominal solar panel input. The BCDC2420 will also charge from an alternator input from a 24 V nominal vehicle . -
Page 7: Charging Process
4.2. CHARGING PROCESS BOOST The Boost stage maintains a constant current until the battery voltage reaches its Absorption Voltage. The current in Boost stage may vary during operation in order to maintain safe operating temperature, or to limit the difference between input and output voltages. ABSORPTION The Charger will then move to Absorption stage which maintains a constant voltage level for a predetermined period of time or until the current being drawn by the output battery drops to less... -

Page 9: Installation
Mount the unit to a flat surface close to the Figure 2: Mounting the Charger auxiliary battery and away from any heat sources. The BCDC2420(-LV) has six wires and should be installed as described over the following pages. The charger operates in any orientation (but it is recommended that the front of the decal be visible). -
Page 10: Fusing
The heavy gauge wires on the BCDC2420(-LV) unit carry peak currents of up to 40 Amps, and it is important to make a good, low resistance, electrical connection that will not degrade over time. -

Figure 5: Ensuring a good wiring connection Crimp both wires to the butt splice using Solder the wires to the butt splice. Ensure single-indent type crimpers. Fold the cable over that a good connection is made. Keep before inserting into the butt-splice as required. heatshrink away until after soldering is Single-indent crimpers should also be used on complete and has cooled. -

Ignition SOLAR INPUT The BCDC2420 is also capable of charging the auxiliary battery from a Solar source. The Unit will accept an input directly from an unregulated 12V nominal solar panels and act as a MPPT Solar Regulator. To select the Solar charging mode, the BLUE ‘Source Select’ wire can either be left disconnected or connected to GROUND. -

Page 17: Frequently Asked Questions
FREQUENTLY ASKED QUESTIONS The BCDC2420(-LV) turns ON at 12.9 V (12 V) and OFF at 12.7 V (11.9 V), but you say it operates down to 9 V, explain? The BCDC2420(-LV) will turn OFF for a split second every 100 seconds to measure the unloaded voltage at the battery. - Page 18 The most likely cause of this issue is that the BCDC is somehow ‘stuck’ in 24 V mode. Try removing the ‘Source Select’ (BLUE) wire and reconnecting it. If the problem still exists please contact REDARC Tech Support. 18 | Frequently asked questions...
