Applications
Efficient, primary switched mode power supply in slim plastic housing. A
powerful and flexible option that's still light and compact. Our real all-rounders,
these power supply units are suitable for a highly diverse range of applications
in solar, measurement and control technology as well as industrial and building
automation. The devices cover the lower and average power requirements from
25 W to 100 W. Versions with 12 V, 24 V, and 48 V are available, enabling a
whole range of applications. A version with 3.8 A rated current is available for
establishing NEC Class 2 circuits. All power supplies also comply with the EN
60335-1 standard for domestic appliances. The output voltage can be easily
set using the rotary potentiometer on the front of the housing. The DIN rail
fastening method and push-in connection terminals enable fast and secure
mounting.
For applications in the medical field, power supplies are available with approval
according to UL 60601-1.
