SYSTEM OVERVIEW

Description: 400V DC Output @ up to 30kW Power System

The NetSure™ 4015, 30kW DC Power System is a complete integrated power system

containing rectifiers, intelligent control, metering, monitoring, and distribution. The

individual system sub-racks can be factory integrated into a standard 19” IT rack or

provided separately for customer integration into an existing IT rack.

This power system is capable of operating either with or without batteries online.

This system consists of the following components.

Power and Control Sub-Rack (List 11, 12)

The system contains one (1) “power and control sub-rack”, which houses up to two

(2) rectifiers and the system control and monitoring components.

Rectifier(s)

The system contains one (1) or two (2) rectifiers, which provide load power,

battery float current, and battery recharge current during normal operating

conditions. Refer to the rectifier instructions (UM1R40015000e) for more

information.

Controls

ACU+ (Advanced Control Unit Plus) Controller

The system controller provides power system control, rectifier control (including a

charge control function), metering functions, monitoring functions, and

local/remote alarm functions. Power system control includes battery low voltage

disconnect (BLVD) functionality to remotely trip battery circuit breakers which

protects batteries against over-discharge. The system can also be equipped with

one (1) or two (2) temperature probe(s). Any combination of the two (2)

temperature probes can be programmed to monitor ambient air temperature

and/or battery temperature. A temperature probe set to monitor battery

temperature can also be used for the rectifier battery charge temperature

compensation feature and/or BTRM (battery thermal runaway management)

feature. The controller also provides data acquisition, system alarm

management, and advanced battery and energy management. The controller

contains an LCD display and keypad for local access. The controller provides

Ethernet connection and supports

software upgrade via its USB port. It also

comes with a comprehensive web page

and SNMP capability for remote system

management. Refer to the ACU+

controller instructions (UM1M820NNB-1)

for more information.

System Shutdown

A “System Shutdown” pushbutton is

located on the front of the power and

control sub-rack. When momentarily

depressed, the rectifier’s AC input circuit

breakers and the Emerson provided

battery trays’ battery disconnect circuit

breakers are tripped open to isolate the

system from all electrical sources.

Manual intervention is required to restart

the system.
