Power supplies for DC control circuits
Phaseo
Universal range
The ambient temperature is a determining factor that limits the power that an
electronic power supply can deliver continuously. If the temperature around the
electronic components is too high, their life will be significantly reduced.
The nominal ambient temperature for the Universal range of Phaseo power supplies
is 50°C. Above this temperature, derating is necessary up to a maximum
temperature of 60°C.
The graph below shows the power (in relation to the nominal power) that the power
supply can deliver continuously, according to the ambient temperature.

There must be adequate convection around the products to assist cooling. There must
also be sufficient clearance around the Universal range of Phaseo power supplies:

Example for ABL 8RPS:
- Without derating, from 0°C to 50°C
- Derating of nominal current by 2% per additional °C, up to 60°C
The nominal power is fixed.
Increasing the output voltage means that the current delivered is
reduced.
To allow heat dissipation, the power supplies must not be in contact with
each other.
