Lovato BCG1212 Automatic Battery Charger 12 V 12 A

Lovato BCG1212 automatic battery charger, 12 V 12 A

The Lovato BCG1212 is a single-phase automatic battery charger for 12 V sealed or non-sealed lead-acid batteries, with a charging current of up to 12 A. It runs from 110 to 240 V AC, has one charging level with a boost of +4.4 percent, and carries protections against short circuit, reversed polarity, low battery voltage and output overload. Seven Star LLC supplies the BCG1212 in Oman and the GCC as an independent supplier in Muscat.

The code BCG1212 reads as family BCG, 12 V battery and 12 A charge current. The BCG1024 with 24 V and the BCG0612 and BCG0524 variants in the same catalogue group follow the same pattern.

BCG1212 technical specifications

How the BCG1212 charges a lead-acid battery

A single-level float charger holds the battery at a constant voltage chosen by the V1 or V2 position, 13.8 V or 13.5 V for a 12 V battery, and delivers up to 12 A while the battery is discharged. The boost function raises the voltage by 4.4 percent after a deep discharge to speed recovery and then returns to float. Adjusting the current limit between 20 and 100 percent matches the charger to a smaller battery so it is never charged with more current than it can accept.

The choice between 13.8 and 13.5 V depends on the battery maker and the ambient temperature: hot battery rooms call for the lower value to avoid water loss and premature ageing.

Protections and alarm of the BCG1212

The unit refuses to charge when the battery terminals are shorted, when polarity is reversed, or when the battery voltage is too low to be a viable battery, and it limits current under overload. A relay contact rated 5 A at 30 V DC can signal alarm conditions to a PLC or annunciator. Always read the instruction manual to see which events operate the relay before wiring a remote alarm.

Where the BCG1212 fits

It backs up control circuits at generator sets (starting batteries), fire pump controllers, switchgear tripping supplies and telecom equipment. Lovato diesel pump and generator controllers such as the FFL700DP and RGK series rely on a healthy 12 V or 24 V battery for starting, so the charger is a natural companion. The 24 V version BCG1024 serves 24 V systems.

BCG1212 selection and ordering checklist

• Battery voltage, chemistry and capacity in Ah
• Charge current as a fraction of the capacity, then set Ic
• Position V1 or V2 per the battery manufacturer and temperature
• Load that stays connected during charging
• Whether an alarm contact is wired
• Ambient temperature range

Installation and maintenance of the BCG1212

Install in an enclosure on a DIN rail or with screws, away from battery gases, and connect the battery with correct polarity before applying the mains. Fuse the battery lead close to the battery. Test by disconnecting the mains and confirming the load remains powered by the battery. Replace batteries on a schedule, because a healthy charger cannot save a worn-out battery.

Typical BCG1212 applications in Oman and the GCC

In the Gulf, high ambient temperatures shorten battery life considerably, so the charger voltage setting and the cooling of the battery enclosure matter. Standby generator starting batteries, fire pump battery banks and remote telemetry boxes are the most common uses.

Sizing the charging current for the BCG1212

A common rule is to limit the charging current to between one tenth and one fifth of the battery capacity in ampere-hours. A 12 A charger therefore suits batteries of roughly 60 to 120 Ah at full current, while a smaller battery needs the current dial turned down towards 20 percent, which equals about 2.4 A. Any load that stays connected during charging, such as a controller, takes current from the same output, so it reduces what reaches the battery. After a long outage, charging time can be estimated from the energy removed divided by the available current.

Do not use the charger as a general DC supply without a battery. Its output is built for battery charging, with a float voltage and boost step, and the ripple and transient behaviour with no battery attached are not stated in the data sheet.

Site conditions in Oman for the BCG1212

Electrical rooms and outdoor panels in the Gulf often operate well above the 25 °C reference temperature used in many catalogues. Before you finalise the BCG1212, compare the expected panel temperature with the operating range and any output derating stated in the manufacturer documentation, and leave the recommended clearance above and below the device for convection. Supply quality also varies between sites, so confirm the input voltage range, frequency and any requirements for protection on the supply side.

Where the device feeds or monitors critical loads, plan how faults will be signalled to the control system and how a replacement can be installed quickly. Keeping one spare BCG1212 per site and recording its settings helps maintenance teams in Oman restore service with minimum downtime.
