ECI Technology
11 - Bravo 10 - 48/120 - User manual - v1.1
4. ECI Technology1
Inverter modules carrying the ECI logo and the EPC mark are triple port converters (AC in, DC in, AC out). Sinusoidal
output is converted from Mains or/and DC.
The block diagram below gives an explicit description of the topology and operation.
The module is built around the following sub-converters:
•AC to DC at input
•DC to DC at input
•DC to AC at output
The energy can flow either from the AC source or the DC source under the control of the local DSP controller. Thanks to
internal energy buffering, the output sine wave is constant and disturbance free regardless of the active source.
The ECI works according to True Redundant Structure (TRS) that features decentralized and independent logic, redundant
communication bus and three internal levels of disconnection to isolate a module after internal failure.
This functionality is included in every inverter module. Running them in parallel provides a modular system with, no
single point of failure, always-conditioned output, high system efficiency and 0 ms source transfer time.
1 Information and data given in this chapter is intended to serve as an overview of the ECI Technology. Detailed features and parameters for each individual
module type in the range may differ and should be referred to in the dedicated data sheet.

ECI Technology
12 - Bravo 10 - 48/120 - User manual - v1.1
4.1 On-line Mode
DC is the primary source of supply whilst Mains (AC) works as the secondary source. Switching time between DC input
and AC input is 0 ms (source transfer). The power delivered by the DC source (usually a battery, but possibly any other
type of DC generator) is converted to provide regulated and transient-free power to the load.
Inverter modules carrying the ECI logo together with the REG mark work only with DC input. Sinusoidal output is converted
from DC with the module operating as a traditional inverter. EPC mode is not available with REG modules.
4.2 Safe Mode
Safe mode uses DC as the primary source of supply while Mains (AC) is on standby.
Mains (AC) is normally disconnected through an internal inlet relay and is only connected when down stream clearance
is required.
The transfer between DC and AC results in a typical transfer time of 10 ms.
Typically the safe mode is used in extremely harsh environments such as railways. Under such conditions, it provides
extra isolation against mains-borne disturbances.
4.3 EPC Mode
Mains input (AC) is the primary source whilst DC works as backup.
The ECI is designed to operate on Mains on a permanent basis and to deliver output voltage conditioned with low THD.
The output sine wave is physically independent of whether the source is AC (or) DC. If the Mains is out of tolerance
or goes down, the converter seamlessly switches to DC and the converter operates in “Back-up mode” (Changeover
switching time is 0 ms).
As soon as the Mains returns to its valid range, the EPC mode is automatically resumed.
The EPC mode offers higher efficiency (up to 94% depending on the model) without compromising the purity of the
output sine wave.
4.4 Mix Mode & Walk-in Mode
Under some circumstances the DC and AC sources can be combined. The sequence is defined by a user selectable set
of parameters. Start, control and exit are fully automatic.
The Walk-in mode where the transfer from DC source to AC source is ramped up within a fixed and adjustable period
of time.

When installing Bravo 10 inverter systems, UL489 listed AC upstream (input) and downstream (output) circuit breakers
are required. Refer section 6.4.6, page 25.
AC Input and Output
•Branch circuit protection breaker should be provided in upstream switchgear regardless of any protective device
already installed at the input of the Bravo 10 system.
•An appropriate branch protection should be provided between the Bravo 10 System and the load.
DC
•An appropriate DC disconnection device should be installed at Input.
Output distribution should be structured to guarantee tripping segregation.Contact the manufacturer for recommendations
and calculation methodology.
•Refer to section 6.4.6, page 25 for sizing protections and connecting cables. All cables must be copper rated
for min 90°C (194°F).
•All cables must be C-UL-US or CSA Listed cables.
•All cables lugs must be C-UL-US or CSA listed. They must be sized according to the rated current of the
converter system and to the customer terminal connection.
•Wire all positions for future expansion.
•Input AC / Output AC / Input DC / Signal cables shall be separated.
•Cable crossings shall be done in 90 deg angles.
•Empty converter positions shall be covered with blank module.
•Bravo 10 system is designed for temperature controlled (40°C / 104°F max) and clean environments. The
presence of airborne particles such as urban dust, sand, metallic dust, and corrosive vapours is forbidden. Install
only in a relatively free of conductive contaminants environment.
6.1 Transformer and Generator Sizing
The inverter is capable of operating at 125% of rated capacity for 15 seconds.
•Transformers supplying AC to the converter should be sized at a minimum of 1.25 times the kVA rating of the
converter to meet this requirement.
•Generators supplying emergency AC to the building and to the converter should be sized at a minimum of two
times the kVA rating of the converter.
