Flatpack2 PS System ~ Telecom The example in Figure 1 represents a typical Flatpack2 PS system for DC power supply of telecom equipment. The system is fed from an external AC mains supply, and consists of rectifiers in power shelves, a controller and DC distribution unit.
1 Introduction Flatpack2 PS System ~ Hybrid Solar The example in Figure 2 represents a typical hybrid, solar Flatpack2 PS system for DC power supply of telecom and industrial equipment. The system is fed from strings of solar panels (DC feed), and uses a diesel generator as AC feed backup at night and during cloudy days, thus ensuring extra battery charging.
1 Introduction Flatpack2 PS System ~ Industrial The example in Figure 3 represents a typical Flatpack2 PS system for DC power supply of industrial equipment, in all areas of the industry, power generation and distribution. The system is fed from an external AC mains supply, and consists of rectifiers in power shelves, a system controller and DC distribution unit.
Flatpack2 DC power systems are implemented by mounting the rectifiers in 23” or 19” power shelves (4 modules across). A wide range of features are implemented in the Flatpack2 module, as mentioned below. Key Features Highest efficiency in minimum space Resonant topology makes the module efficiency industry leading, and contributes to the module’s ultra compact dimensions.
Read also chapter “Keying Scheme ~ Modules and Power Shelves”, page 19. CAUTION: Never install Flatpack2 modules in power shelves with different output voltage than the module’s. The module’s output voltage and the power system’s output voltage must always be the same.
Rectifiers — Output Voltage Lower than 60VDC Flatpack2 Rectifier 24V, 1800W HE Part number 241115.205. For description, refer to chapter “Flatpack2 Rectifier 48V, 2000W HE”, page 11. For technical data, read chapter “Specifications Flatpack2 Rectifier 24V, 1800W HE”, page 23.

The technical specifications for “Flatpack2 Rectifier 48V, 2000W BF” are the same as for “Flatpack2 Rectifier 48V, 2000W”, except for their heat management and operating temperatures, which are: “Flatpack2 Rectifier 48V, 2000W”...
2 Flatpack2 Rectifier & Converter Modules Rectifiers — Output Voltage Higher than 60VDC Flatpack2 Rectifier 110VDC, 2000W HE WOR - (Industrial) Part number 241115.805. High efficiency rectifier for DC power supply facilities with or without battery in all areas of industry, power generation and power distribution.
2 Flatpack2 Rectifier & Converter Modules Flatpack2 Rectifier 220VDC, 2000W HE WOR - (Industrial) Part number 241115.815. High efficiency rectifier for DC power supply facilities with or without battery in all areas of industry, power generation and power distribution. With efficiency up to 95.3%, the losses have been reduced by 50% compared to the current industry standard.
2 Flatpack2 Rectifier & Converter Modules Flatpack2 Rectifier 380VDC, 2500W HE - (Data Centres) Part number 241119.825. High efficiency rectifier for High Voltage DC power supply facilities in data centres, central offices, HVDC UPS, etc. This module enables implementing large systems of up to 2.4MW, e.g.
The Flatpack2 HE SOLAR charger is suitable for any telecom site with autonomous (solar only) or hybrid solar power. It can be used in parallel with any other Flatpack2 rectifiers (front-to-back air flow systems only) fed by generator or unreliable mains, on hybrid sites.
CAUTION: Do not relocate already hot-plugged modules to other positions in the power shelf. New Flatpack2 modules must be hot-plugged in the power shelf, one at time, starting with position 1, 2, 3 and so on. This is usually performed before shipment of the system. Read your system’s quick start guide for more information.
A non-keyed power shelf will allow both keyed and non-keyed modules to be plugged in the shelf. CAUTION: Never install Flatpack2 modules in power shelves with different output voltage than the module’s. The module’s output voltage and the power system’s output voltage must always be the same.
The AC Input Connections are not polarity sensitive, even when the system uses DC input feed instead of AC input feed. CAN Bus Addressing (plug-and-play) When a Flatpack2 module is hot-plugged in the power shelf the first time, the system’s main controller automatically assigns the module with the next available ID number (CAN bus address).
