TSI TECHNOLOGY
4. TSI TECHNOLOGY 1
Inverter modules carrying the TSI 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 here 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 TSI can handle continuous over load of 110%, It can also handle overload capacity upto 150% for 15 seconds.
The TSI output Voltage, Frequency, and Mode can be selected and controlled by selector switches and Front (ON/
OFF)/,remote (ON/OFF) respectively.
The TSI has a PFC alarm (major and Minor) to indicate the status of system.
The TSI can be deliver full power up to 50°C (122°F) ambient and in higher ambient DSP automatic derating the power.
The functionality is included always conditioned output, high efficiency and 0ms source transfer time.
1) Information and data given in this chapter intend to for an overview on the technology. Detailed features and parameters for each individual module type of the
range may differ and should be referred in the dedicated data sheet.

10 – TSI Y-One 230 VAC – User manual – v7.4
TSI TECHNOLOGY
4.1 On-line Mode
DC is the primary source of supply whilst Mains (AC) works as the secondary source of supply. Switching time
between DC input and AC input is 0 ms (source transfer).The power delivered by the DC source (usually a battery, but it
could be any other type of DC generator) is converted to provide regulated and transient free power to the load. In case
of short circuit at the load side, the boost is automatically and timely energized to trip downstream protective devices.
4.2 Safe mode
Safe mode use DC as primary source of supply while Mains (AC) is in standby.
Mains (AC) is normally disconnected through internal inlet relay and is only connected when down stream clearance is
required (boost) or if DC is unavailable.
The transfer between DC and AC results in typical transfer time of 10 ms.
Typically the safe mode is used in extremely harshed environments such as railways. Under such conditions it provides
extra isolation against disturbances carried by the Mains.
4.3 EPC-mode
Mains input (AC) is the primary source whilst DC works as backup.
The TSI is designed to operate on Mains on permanent basis and to deliver output voltage conditioned with low THD.
There is no physical difference on the output sine wave 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”
(Switching time back and forth is 0 ms).
As soon as the Mains returns in to valid range, the EPC mode is automatically resumed.
The EPC mode offers higher efficiency (up to 96% depending on the model) without compromising the purity of the
output sine wave.
Note: REG modules
Inverter modules carrying the TSI logo together with REG mark are modules working only with DC
input . Sinusoidal output is converted from DC and the module operates as a traditional inverter.
EPC mode and the boost are not available with REG modules.

Installation

6.2 Wiring
Caution:
The TSI Y-One has internal fuses on both DC & AC inputs.
Those devices do not protect the upstream cables connected to DC & AC inputs and upstream
breakers or fuses shall be set up in accordance with AC & DC wires ratings, to meet the local
national electrical code standard.
All breakers, cables and wires should be classified for min 90°C (194°F) operation. Matching
respectively Line / Neutral feeder to Line / neutral input connections is required.
Before any intervention on the TSI Y-One inputs, operator has to make sure that power is
switched off on both DC leads and AC input mains.
Some safety labels are stuck on the TSI Y-One. They must not be removed.
It is strongly recommended to install external surge arrestors upstream to the AC input terminal
at the cabinet & the room/building levels with related energy ratings.
The insulation cover of conductors must meet the local and international standards and the cross section must be
related to the upstream protections.
