Application Challenges

Reliable Power for Essential Operations

01 The Challenge

Sourcing and Support

Finding a dependable charging system manufacturing and supported in the United States

How the BC-2500 Helps

Designed and manufactured by Lester Electrical in Lincoln, Nebraska, the BC-2500 delivers consistent quality backed by responsive U.S.-based support.

02 The Challenge

Compliance and Battery Protection

Meeting safety and efficiency requirements while protecting battery performance and service life.

How the BC-2500 Helps

The BC-2500 complies with CEC requirements, UL 1012, NEMA PE 5, and FCC Part 15. Remote voltage sensing and temperature compensation help maintain accurate, efficient charging under changing conditions.

03 The Challenge

Harsh Operating Conditions

Maintaining reliable charging in high temperatures, severe weather, and demanding industrial environments

How the BC-2500 Helps

Heavy-duty construction, operation up to 70°C, fan-free natural-convection cooling, low DC-output ripple, and conformal-coated circuit boards provide dependable performance and added protection.

04 The Challenge

Installation Constraints

Accommodating different input power, mounting, and wiring requirements without adding installation complexity.

How the BC-2500 Helps

Universal 100–240 VAC input eliminates manual tap or jumper changes. Wall-, shelf-, and floor-mount configurations and four conduit knockout locations provide installation flexibility.

05 The Challenge

Continuity During Equipment Issues

Preventing a single component issue from compromising the entire battery-charging system.

How the BC-2500 Helps

Its modular architecture provides built-in redundancy, helping maintain charging if an individual power module needs service and allowing personnel to focus on higher-priority operations.
