BS Series 2U Rackmount Modular DC Rectifier & Battery Charger
Modular Rackmount Rectifier and Battery Charger for DC Power Systems
The BS Series is a 2U rackmount modular DC rectifier and battery charger system, offering 24V, 48V, 110V and 220V DC configurations for telecommunications, data centres and industrial power applications.
The BS Series is a rackmount switch-mode DC power system designed to provide regulated DC output and battery charging functions. Its modular architecture combines rectifier modules with system monitoring in a compact 2U, 19-inch rackmount configuration.
The system supports different DC power capacities through parallel rectifier module configurations. Hot-swappable modules, capacity expansion and N+1 redundancy arrangements allow the system to be configured according to power demand and redundancy requirements.
Available with nominal DC outputs of 24V, 48V, 110V and 220V, the BS Series can operate with or without batteries. Its monitoring and protection functions support the management of DC power distribution and charging requirements.

SYSTEM FEATURES
Modular DC Power and Battery Charging Features
The BS Series combines rectification, charging, monitoring and protection functions in a modular system designed for capacity expansion and serviceability.
Hot-Swappable Modules
The modular system uses hot-swappable rectifier and monitoring modules, supporting module servicing and replacement within the intended system design.
Capacity Expansion
Parallel rectifier module arrangements allow DC output capacity to be increased according to the selected modules and overall system configuration.
N+1 Redundancy
The modular architecture supports N+1 redundancy configurations for applications requiring additional rectifier capacity beyond the normal operating requirement.
LCD and LED Monitoring
LCD and LED indicators provide system operating information. The brochure also identifies RS232, RS485 and dry-contact communication functions.
Battery Charging Support
Constant-current and constant-voltage charging characteristics support battery charging arrangements, while the system also permits operation without connected batteries.

MODULE CONFIGURATIONS
Published Rectifier Output Ratings
The product brochure lists different rated output currents for single-phase rectifier configurations. The complete system can use parallel arrangements for higher current requirements or redundancy.
| Nominal DC Output | Listed Rated Current Options |
|---|---|
| 24VDC | 60A / 120A / 180A |
| 48VDC | 50A / 100A / 150A |
| 110VDC | 20A / 40A / 60A |
| 220VDC | 10A / 20A / 30A |
These are the brochure's listed single-phase rectifier ratings, not the total output current of every assembled system. Confirm the selected module and parallel configuration when specifying the required DC output.
