Note
Red Pitaya devices:
should be operated at normal conditions with ambient temperatures not exceeding 30°C (86°F) and should not be covered.
are intended for indoor use at a maximum altitude of 2000 m, pollution degree 2, and relative humidity less than 90%.
intended for use with low-voltage energy sources and signals; it should not be used in any direct connection with voltages above 30 volts.
Warning
All inputs and outputs available through SMA and BNC connectors share a common ground connected to the power supply ground.
Warning
Power supply precautions:
STEMlab 125-14, STEMlab 125-14-Z7020, STEMlab 125-14 4-Input, STEMlab 125-10, SDRlab 122-16 shall only be powered by an isolated external power supply providing 5 volts direct current, and a maximum current of 2 Amperes. The KA23-0502000DES model is recommended. Any other external power supply used with Red Pitaya must comply with relevant regulations and standards applicable in the country of use.
SIGNALlab 250-12 shall only be powered by an original KA2401A 24V/1A isolated power supply or through RJ45 ethernet connector (PoE version only).
