The power supply can also be used on two-phases of a three-phase-system.
Such a phase-to-phase connection is allowed as long as the supplying
voltage is below 240V+15%. Use a fuse or a circuit breaker to protect the N
input. The N input is internally not protected and is in this case connected to
a hot wire. Appropriate fuses or circuit breakers are specified in section 23.4
“External Input Protection”.
23.12.USE IN A TIGHTLY SEALED ENCLOSURE
When the power supply is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher
than outside. In such situations, the inside temperature defines the ambient temperature for the power supply.
The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure.
The power supply is placed in the middle of the box, no other heat producing items are inside the box
Enclosure:
Rittal Typ IP66 Box PK 9516 100, plastic, 110x180x165mm
Load:
24V, 3.4A; (=100%) load is placed outside the box
Input:
230Vac
Temperature inside enclosure:
41.3°C (in the middle of the right side of the power supply with a distance of 2cm)
Temperature outside enclosure: 25.1°C
Temperature rise:
16.2K
Nov. 2011 / Rev. 2.1 DS-QS3.241-EN
All parameters are specified at 24V, 3.4A, 230Vac, 25°C ambient and after a 5 minutes run-in time unless otherwise noted.
