Product overview
The SER100040K3B combines 40 kW output, a 50-1000 V DC range and a stated peak efficiency of 97%. Its -40°C to +75°C operating range supports charger designs for demanding climates, while the 300-1000 V constant-power range and 133 A current limit provide a clear engineering envelope for system integration.
Key Product Advantages
● 40 kW per module
Enables high cabinet power with fewer conversion units and interconnections.
● 97% peak efficiency
Reduces conversion losses and cooling load under specified operating conditions.
● Wide temperature range
Operation from -40°C to +75°C is stated, with derating above +55°C.
● 50-1000 V output
Supports broad battery-voltage coverage for next-generation charging platforms.

Module Size, Efficiency and N+1 Redundancy
Fewer modules simplify assembly Higher power per module reduces connectors and addresses for a given cabinet rating.
Each module outage removes more capacity N+1 strategy should compare acceptable reduced output with the 40kW step size.
Efficiency changes cooling demand At 97% peak efficiency, remaining losses still become heat; use full efficiency curves for thermal design.
Engineering checkpoint: Define minimum available charger power after one module failure and verify the controller's derating and alarm behavior.
Selection Guidance
01
Choose the 40 kW module when cabinet density, efficiency and environmental range justify the higher per-module capacity.
02
The host cabinet must provide the required input current, airflow, temperature monitoring and fault isolation.
03
Review acoustic performance, fan service, redundancy targets and N+1 strategy: fewer high-power modules can simplify assembly but may increase the capacity lost when one module is unavailable.
Recommended Applications
●High-power integrated DC chargers
●Climate-exposed charging equipment
●Space-constrained charger cabinets
●Heavy-duty and fleet charging systems
●High-efficiency platform upgrades
