,Hot Plug DC Power System
The CTOS0502 Compact HE Flatpack S 2U DC Power System is a highly integrated rack-mounted power solution launched by Eltek. Equipped with the classic Flatpack S 48/1800HE high-efficiency rectifier and Smartpack S intelligent controller, this all-in-one unit integrates power conversion, distribution, and monitoring functions. It adopts a 2U low-profile design with a shallow depth of only 270 mm, making it compatible with most standard cabinets and an ideal replacement for legacy power equipment.
The system supports 85–305 V AC and 85–250 V DC dual wide input, with a rated output of −48 V DC, maximum current up to 150 A, and total output power reaching 9 kW. All rectifier modules, controllers, and circuit breakers support hot plugging, enabling maintenance without power interruption. Built with diversified power distribution circuits and optional LVBD/LVLD protection functions, it complies with multiple international electrical and EMC standards. This reliable power system is widely deployed in mobile communication base stations, fiber access networks, and other telecom scenarios.
- All-in-One Integrated Design: Combines rectifier, controller, and power distribution in one 2U unit. Plug-and-play, simplifying on-site assembly and wiring work.
- Full Hot Plug Function: Both the rectifier and Smartpack S controller support hot swapping. Modules and breakers can be replaced without system shutdown to reduce operation downtime.
- Wide Input Compatibility: Works with 85–305 V AC and 85–250 V DC dual input, adapting to unstable power grids and generator power supply in different regions.
- Diversified Distribution Layout: Comes with 4 large breaker positions and 10 × 30 A pluggable MCBs. Supports flexible power distribution for multiple loads.
- Dual Protection Options: Equipped with standard LVBD function and optional LVLD protection, effectively protecting batteries and key loads from damage.
- Remote Monitoring Capability: Embedded Ethernet port enables real-time data viewing, parameter configuration, and remote fault alarms for unattended management.
- Standard Rack Specification: 19-inch flush mounting, 270 mm shallow depth, suitable for various compact cabinets and limited-space deployments.
- High Efficiency & Stability: Matched with high-efficiency rectifier modules to lower heat generation and power consumption during long-term operation.
- Strict Standard Compliance: Passes UL60950-1, EN series safety and EMC certifications, meeting global telecom deployment requirements.
