Non-stabilized DC power supply, three-phase
DNC 24-30 C
Characteristics
General data
The robust, unregulated DC power supplies of the DNC series focus on the core task of voltage and current supply while meeting the requirements for safety isolating transformers according to EN (IEC) 61558-2-6. The power supply features high overload capacity, and the DC OK status is indicated by an LED.
Benefits
› Insensitive to surge voltage and transients
› Excellent corrosion protection and low noise emission thanks to BLOCK IMPEX vacuum impregnation
› Output-side configuration with MKT capacitors
› Varistor protection circuit
› Touch-protected connection terminals according to UVV BGV A3
