Applications
These three – phase dc power supplies of the DNT series supply an unregulated DC voltage of 24V DC with a residual ripple of <5% under nominal conditions.
Description
These devices are designed to operate electrical and electronic DC devices. They are also particularly suitable for operating your PLC cost-effectively and reliably.
For safe grid separation, three-phase safety transformers built according to EN61558-2-6 are used. The devices comply with protection class I.
The three-phase bridge rectifier with downstream filter capacitor ensures a residual ripple of typically 4.2%. The output is additionally connected to a varistor and protective capacitor. The readiness for operation is indicated by a green LED. The terminals used are finger-safe and comply with VBG4. The power supplies can be operated up to an ambient temperature of 40 ° C with rated power. In order to achieve higher output currents, or to retrofit systems, devices of the same type can be operated in parallel. The total current is reduced by approx. 10% compared to the individual output currents.
The installation of the devices must be done vertically. The DC power supplies are compact and easy to install due to their construction
