The COSMO 1500 - 1500/1 - 3000 series of power supplies are
supervised by a microcontroller. These power supplies are protected
against polarity reversal, short-circuit and overvoltage and can be
connected in series and in parallel so they can be used in assembly
lines or wherever high voltage and current are required.
Control mode
The power supply can work both in voltage mode and in current
mode, depending on the use and/or the type of load it is intended
for. The currently active control mode is shown by the position of the
arrow to the left of the controlled quantity field. Refer to the illu-
stration below.
V = 13.8 VOLT
I = 2.50 AMP.
operation in voltage mode
Enabling the output
The output is enabled or disabled by pressing the push button 7.
Adjusting the maximum voltage
The power supply lets you set a maximum voltage value in excess of
which the output is automatically disconnected..
To set the maximum voltage value,
follow these instructions.
a) turn the knob 10 all the way to the right

b) press the push button 9; by doing this, the power supply is auto-
matically disconnected from the load and enters into the OVP
adjustment mode, as shown in the illustration below.
SET VMAX = 32.0
OUT DISABLE
b) adjust the maximum voltage by slowly turning the knob 10 to the
left
c) press the push button 9 again to exit the adjustment phase.
Note: we recommend you set the maximum voltage value when
the voltage and current adjustments have already been
performed so as to avoid activation of the protection during
the adjustment phase.
Overtemperature protection
If the temperature of the dissipators exceeds 80°C, the output is
disabled and the following message is given:
OVERTEMP. PROTECTION
In the event this occurs, wait for the temperature to lower and reactivation
of the output.
Note: in those cases where the protection intervenes to ascertain the
above-mentioned anomalies if the power supply is switched off, it is
temporarily reset; therefore, if the anomaly persists when the power
supply comes back on, it deactivates after the initialisation phase.
