Rectifiers and battery chargers
Naval battery chargers
Thyristor-controlled and N+1 SMPS battery chargers, 24 V to 550 V, for naval ships and shore installations.
Overview
What it does
Stationary battery chargers for naval ships and defence installations in thyristor-controlled and modular SMPS (N+1) designs, with output voltages from 24 V to 550 V.
Thyristor chargers run from 230 V or 415 V, 50 Hz input and deliver 15 A to 1,500 A with output regulation below 1%.
Chargers are offered as free-standing panels, mobile trolleys or container-type structures, in float, float-cum-boost and redundant configurations.
Applications
- Battery charging on naval ships
- Shore and dockyard DC systems
- Defence installations and stationary battery banks
Features
Why engineers choose it
- Automatic float/boost and CC/CV charging
- Cell monitoring and monitoring ports
- Configurations: float-cum-boost with dropper diodes, dual redundant, multiple chargers with standby unit
- N+1 redundant SMPS modules for 24–220 V DC systems
- In-house transformer manufacturing and wiring
- High transient response under load and line variations
