INTRODUCTION
Many thanks for the choice of our products; we are in a position to grant you high quality
products, which follow high quality insurance models, UNI EN ISO 9001 and which use
the best materials that modern technology is able to offer.
Our products are the synthesis of the experience that our engineers have gained in the
field of planning and in the realization of uninterruptible power supplies, DC-AC inverters,
power supplies, emergency light device, emergency DC power supply and a lot of
customized products.
Every device is given with an “ only and personal test certificate “; the final check up is
entrusted to an automatic machine (run by a personal computer), which provides a
checking up certificate with the real data at the end of the process.
CAUTION !
Read through this manual respecting all the safety
instructions, during the installation and the use of the
device, as it works using dangerous voltages and currents.
SEE EMERGENCY SWITCHING OFF PROCEDURE.
Always refer to this manual for further references.

GENERAL DESCRIPTION
The Voltage & frequency regulator is composed as follows:
RF INPUT FILTER – EMI filter.
INPUT SWITCH – Input AC automatic switch. Mains protection.
INPUT RECTIFIER – Bridge rectifier.
LIMIT-IN CIRCUIT-Limit-in board. It is used to provide soft charging of internal
capacitors (40 seconds) during start up procedure. (see “start-up procedure” section)
IGBT CONTROL UNIT (SINUSOIDAL INVERTER) - The inverter electronic circuit has been planned
with pulse width modulation system (PWM) ; it provides control to drives IGBT power module and to
protect it against short circuit, overload etc. An output electronic feed-back is provided directly from
output due to reduce the transformer loss voltage insertion.
IGBT POWER MODULE – It is composed by a power IGBT and its driver.
RF OUTPUT FILTER – EMI filter.
OUTPUT AUTO-TRANSFORMER – The output transformer translates the voltage from
IGBT (nominal 230Vac) into an higher voltage (about 270V). It is an auto-f transformer. It
is included only in 20 & 30A version. An output coil associated to IGBT module, provides
the perfect output sine wave
The transformer is not used in three phase input version.
CONTROL UNIT – Provides acoustic and visive alarms and functioning situation. It also
control the 50/60Hz selector and external enable & 0-10V control input.
LCD DIGITAL DISPLAY – Output voltage and current indication (this is not an
instrument).
OUTPUT SWITCH – Output AC automatic switch. Output disconnection and protection
device.

REMOTE BOARD DB9 CONNECTION
WARNING!: To prevent possible damage, using REMOTE CONTROL is
always necessary connect GROUND BOLT.
WARNING!: During REMOTE CONTROL situation, please turn the frontal knob in the
minimum output voltage level.
Verify the frontal knob voltage setting is always recommended!.
When “remote enable” is disabled, the output voltage comes back immediately to level
setting by frontal knob.
