7.2.1. Supply Voltage X5
Pin
Name
Function
1
SV+
Supply voltage plus
2
GND
Power GND (supply voltage minus)
SV+
(X5-1)
Supply voltage plus
Supply voltage:
15.0 V … 48.0 V (max. 50 V)
Supply current:
depends on the output load (max. ~15A)
There are no internal fuses. The supply voltage has to be fused external.
Supply voltage should be approx. 10% above maximum Peltier voltage.
Make sure that the supply wiring (SV+ and GND) is as short as possible.
Warning:
There is no inverse polarity protection for the supply
voltage. Wrong polarity may damage the device
substantially. This will void the warranty.
