TECHNICAL FEATURES OF THE STELVIO1800 SERIES
The innovative characteristics of the STELVIO1800 range of battery chargers are the following:
1.
Slim form factor for on board and off board installation.
2.
Protection grade IP20.
3.
Advanced technology
High frequency
system.
4.
Active PFC.
5.
Resonant technology
6.
Charging process fully controlled by microprocessor.
7.
Input voltage: 200-240 Vac 50-60Hz.
8.
Charging process start in the “soft start” mode.
9.
Protection against polarity inversions, short-circuits, over-voltages or anomalies by means of a fuse.
10.
Signaling of possible anomalies by red LED flashing and LED bar.
11.
Insensitive charge parameters in case of ±10% network voltage oscillations.
12.
Efficiency > 90%.
13.
Control card powered directly from battery (except for lithium battery, in this case an internal power supply is fit).
OPERATING PRINCIPLE OF THE STELVIO1800
Stelvio control board is powered directly from battery so for power on it as well as connect the mains is necessary
connect the battery. After the battery connection the control card perform its self-check and if all ok starts to charge
blinking the yellow led/bar, otherwise if has been recognized errors the red led/bar blink.
The blinks number of yellow led/bar are the number of curve phase.
The blinks number of red led/bar are the error code.
If the user disconnects the battery from the battery charger during the charging process, the battery charger stops
immediately the charge and power off itself (control board no longer powered).
The progress of the charging process is shown by two LED’s and a multicolor led bar: yellow and green, as in the
whole range of the battery chargers.
The green LED shows the end of the charging or the last phase in case of deep charging process.
VISUAL SIGNALS
Please find in the following table a list of the visual signals of the STELVIO1800 series.
SIGNAL (LED)
MEANING
X Yellow LED/BAR blinks
X = number of blinks are the number of curve phase
Green LED/BAR on
End of charge or maintenance phase
Blue led on
Mains connected
ANOMALIES
X Red LED/BAR blinks
X = number of blinks are error code
5 = phase timeout
12 = charging process timeout
3 = power supply fault
4 = internal bus voltage fault
1 = calibration error
10 = over temperature
