Introduction to each module of the power composition system:
1 Rectifier module
POWEC rectifier module is a plug-in modular and intelligent rectifier with frequency modulation resonance technology and power factor compensation, abbreviated as PMP (Powec Modular Power). PMP11.48SIC is a plug-in modular rectifier with power factor compensation, which adopts high-frequency resonant switching technology and is particularly suitable for the telecommunications field. Input: 205~250 V AC ± 10%, output: 48 V DC, 1100 W; It has the advantages of wide input voltage range, power factor compensation, dynamic load sharing, hot swapping, no need for fan cooling, and light weight (3.1 kg).
2 Control module
The control module is used to monitor the operation of the power system, with clear text expression for all information, guided menu and window operation, and RS232 interface, abbreviated as PCU (Powec Control Unit)
PCU 10.24-48D is a microprocessor based control unit that can monitor the power system composed of PMP10.00 SIC rectifier and PMP11.48 SIC rectifier. Input: 18-72 V DC. It has the advantages of providing clear text information, guided operation, battery discharge testing function, RS232 testing function, additional alarm contacts for connecting external alarm devices, and various parameter settings.
PCU10.24-48D is a microprocessor based alarm and control unit that can monitor an additional 17: PMP10.00SIC or PMP11.48SIC modules located on three subracks. This plug-in module can monitor the system's mains input, output voltage, current, and the working status of the PMP module, while also monitoring external conditions such as distribution fuses, load or battery detachment relays, battery capacity testing, battery symmetrical voltage, temperature, etc. The control menu is simple and provides operation guidance, and the system is operated through the buttons on the front panel. The additional alarm contacts on the alarm interface board (0398) can be used to connect external alarm devices.
Alarm: DC high voltage alarm, DC low voltage alarm, load/battery detachment alarm, DC fuse fault, module fault, mains fault, battery fault, symmetrical alarm, high temperature alarm, overload alarm.
All alarms are indicated by LEDs and displayed on the display screen, with 4 free common contacts inside providing alarm signals to the outside. In addition, two Open collector outputs are used to realize low-voltage disconnection function.
Display: 2 * 16 character LCD display screen is used to display output data, alarms, information, etc.
Communication: Remote monitoring of the system is carried out through PowCom or PAS software on a personal computer and RS232 serial interface.
3 subracks
The subrack is used to install rectifier modules, and can also be mixed with control modules. In small systems, DC distribution units, battery fuses, etc. can also be built-in, achieving * savings based on the system composition
