New Alternator technologies like smart alternators or charge-reducing alternators require sophisticated dual battery systems to function correctly. The DBM20A can be configured with IGN-Signal (Ignition) for correct detection if the car is running and charging. 3 different charge levels/battery types with or without an additional equalize mode are user selectable. -

In the past, the alternator charged the starter battery as soon as the engine was running. Classic dual battery systems such as the IBS-DBS or IBS-DBR, also known as VSR, Voltage Sensing Relay, charge the auxiliary battery easily and reliably during this time. -
Page 5: Alternator Types
If an IBS-DBS is also installed on the DBM20A, it is very important that the correct programming of the DIP switch settings (see page 8 in the IBS-DBS manual) is carried out, especially the lithium and DBM20A configuration. -
Page 6: Applications
Applications In this overview the three main applications are shown with their options. Technical Informations The DBM20A provides a 3 to 4 step charging programm: 1. Step: Bulk The Bulk step is the first step of charging. In this step the battery is... -

5 seconds of inactivity. If the configuration mode is not started, the DBM20A starts with a fast flashing pattern, in the default mode (Low Level/Lead-Battery/80-150Ah) or the last saved configuration. -
Page 9: Charge Select Indication
Configuration charge setting When the DBM is in the charging setting, the relay LED lights up green. Six different charging modes can be set in this configuration step. If a short ground contact is made with the Link / Prog line, the system switches to the next charge level. The 6 selection levels repeat in a cycle. -

Link/Prog wire (with installed Link-Button these contacts can be made by pushing the Button or with installed IBS-DBS by pushing the link Button on the monitor [with IBS-DBS make sure to push auto Button when the DBM20A changed to Stand-by mode). -
Page 11: Mounting
Mounting Mount the DBM20A with its wires facing downwards close to the Aux Battery on metal auto-body panel to provide the best cooling. Do not mount close to hot engine parts such as exhaust or turbo charger. The DBM20A will typically warm to around 40°C depending on application. -

Two DBM20A can be operated in parallel, resulting in a maximum charging current of up to 45A. This new function is only supported if no relay is installed in the system (no link start kit or no IBS-DBS dual battery system with relay). Depending on the load behaviour, both systems work with full power, with partial load or low power, a DBM20A, a "loading error"... -

Page 20: 24V / 12V Parallel Operation Of Dbm20A
24V / 12V parallel operation of DBM20A To achieve a higher charge current in a 24V/12V system it is possible to operate up to three DBM20A in parallel. This allows a charge current up to 60A. ATTENTION: Parallel operation of DBM20A is only possible in 24V/12V systems! -
Page 21: Solar
Solar The DBM20AS has a solar input (pink cable) that supports up to 12A charging current. This enables the connection of up to 250W panel power. When a solar panel is recognized by the system, the Equalize LED flashes green. When Equalize mode is active, it is only displayed every 20 seconds in standby mode. -
