Doghouse BC-2500 Industrial Battery Charger

The Doghouse BC-2500 is a compact, modular DC battery charger designed for substations, switchgear, and other industrial applications where space, reliability, and continuous operation are critical.

The Doghouse BC-2500 uses multiple independently operating intelligent Power Modules, or iPMs, instead of relying on a single power-conversion component. The modules share the connected load, helping eliminate single points of failure and maintain DC output if a module becomes unavailable.

Multiple iPMs operate in parallel and distribute the load across the charger. The system can be configured with N+1 or N+2 redundancy so the remaining modules continue charging if one or more modules are taken offline.

Yes. The iPMs are hot-swappable and can be removed by loosening two screws. A module can be replaced while the remaining modules continue supporting the battery and connected DC load.

The charger combines multiple iPMs within one compact four-slot chassis. This reduces the amount of equipment required while providing modular capacity and redundancy for demanding DC control-power applications.

The four-slot chassis measures approximately 17.125 × 12.78 × 17.28 inches and weighs approximately 28 pounds when unloaded. Its compact construction makes it easier to position in substations, switchgear rooms, and other space-constrained installations.

The Doghouse BC-2500 can be installed on a wall, shelf, floor, or EIA 19-inch rack. Rack installations can be configured for front or rear mounting.

The charger accepts single-phase AC input with a rated range of 100–240 VAC and an operating range of 90–264 VAC. It supports rated frequencies from 50–200 Hz and operating frequencies from 45–205 Hz. Operation below 100 VAC may reduce the charger’s available output power.

Yes. The User Interface Module can be powered by either AC or DC. When AC power is lost, the connected battery can continue powering the user interface, monitoring functions, and alarms.

Yes. The battery eliminator capability is included as a standard feature. The charger’s low-output ripple allows it to operate as a filtered DC power supply for connected DC loads.

The charger uses natural convection cooling and does not require cooling fans. This removes fan-related failure points and helps support dependable operation in demanding industrial environments.

The Doghouse BC-2500 operates from -40°C to 70°C (-40°F to 158°F). The 48 VDC and 130 VDC configurations operate in reduced-power mode when temperatures exceed 50°C.

The charger is rated for environments with 0–95% non-condensing humidity. Its circuit boards are conformal coated to provide added protection against moisture.

At full load, the charger provides greater than 91% efficiency with a 120 VAC input and greater than 93% efficiency with a 240 VAC input.

The charger includes protection against current-limit conditions, short circuits, reverse polarity, surges, lightning-related transients, inrush current, undervoltage, and overvoltage.

Yes. Battery temperature compensation with controlled limits is available to adjust charger operation based on battery temperature. Ten-foot and 30-foot battery temperature sensors are available through the product configuration options.

Yes. A digital amp and volt meter is included as standard. The charger also includes an internal web server and can be connected directly to a laptop for configuration or monitoring.

The charger can be configured with standard 10 kAIC magnetic breakers or optional high-interrupt 22 kAIC magnetic breakers.

Yes. The charger can be configured with a ground fault detection switch. Configurations are available with no GFD switch or with a GFD switch that is turned off by default.

Yes. Remote DC voltage-sensing wiring is available in 10-foot and 30-foot lengths. Remote sensing allows the charger to account for voltage at the connected battery rather than relying only on voltage measured at the charger output.
