EverExceed 48v three phase diode bridge telecom Rectifier with EHDVS-336 high DC voltage system

EverExceed High DC Voltage System---EHDVS-336 system is designed for applications operating up to 336VDC power system. The foundation of the system is a latest, proven 10kW rectifier, featuring high frequency switching technology in a compact package.

Equipped with these rectifiers, this 336V DC power system offers high efficiency over a wide operating range and exceptional reliability. Full galvanic isolation eliminates the cost and complexity of an external isolation transformer.A flexible and modular design enables deployment in a variety of site configurations and allows for scalable build-outs to avoid
stranded capacity.

• Telecom – Cable savings due to copper cable reduction compared to -48V DC
• Data Centers – Simple architecture with few power conversions offers high reliability
• Commercial Building Microgrids –Easy integration of renewable energy sources

The 10kw high efficiency rectifier converters standard AC supply voltages
into stable 336VDC, adjustable up to 400VDC. Each unit in the system
operates independently and delivers conditioned, isolated power onto a
common distribution bus. The rectifiers function in parallel for seamless
redundancy and load sharing within the system .These pure three phase
rectifiers provide ideally balanced currents back to grid with low harmonic
content.
The rectifiers are designed with the latest soft switch-mode technology,
using DSP (Digital Signaling Processor)functionality for efficient
operation.Rectifiers are designed to be hot-swapped into operational
systems by trained personnel. This allows rectifiers to be added for
expansion or removed and replaced for maintenance, with no interruption
to the critical load.

The flexible, modular architecture of the EHDVS-336 can easily be configured to meet the needs of a number of
deployment scenarios. Depending on the output distribution topology chosen, the distribution section of the
power module can be integrated with either:
Load distribution panels are used to feed powered equipment racks. Bulk distribution panels can be used to
feed a bus way system or LDPs in an additional
Distribution Module. Load breakers can be added or changed in the field as needed.
Each Distribution Bay can contain up to two LDPs, which can be configured for A+B feeds, or connected
together to provide more breaker positions.

A matching battery cabinet is specifically designed for use with the EHDVS-336 Series. LFP(lithium iron
phosphate) battery options is standard configuration for this system, and VRLR battery is available.
Each battery cabinet holds 48V*7 battery blocks configured in 336V nominal battery string. A single string can
supply several minutes of backup time in particular situation(load capacity and battery capacity) . This energy
system configuration with multiple function , such as BMS, remote communication, perfect protection function
and so on.

The main controller provides primary power system control, alarm management, data acquisition, and
advanced battery and energy management. Low voltage disconnect (LVD) functionality is provided to remotely
trip battery circuit breakers and protect batteries against over-discharge. If equipped with optional temperature
probe(s), the controller can support battery charge temperature compensation. Temperature probe(s) may also
be designated to monitor ambient air temperature. The EHDVS-336 ships pre-configured from the factory.
The controller has a local touched-LCD display, keypad and Ethernet port for remote connectivity through
TCP/IP or CAN2.0. Access to an internal web interface for remote system management is provided. The control
section also contains the ground fault monitoring hardware and
algorithms.
The EHDVS-336 has several maintain- ability and redundancy
features built into the controls section. The modular controller is
hot-swappable, allowing for field replacement or upgrade and the
entire controls section can be removed from an operating system
for replacement or repair without disturbing the output bus.
Additionally, redundant power supplies are provided to ensure
maximum uptime of this sub-system.
