Three-phase DC power supply RDRK 2.5–60 (K)

THREE-PHASE DC POWER SUPPLYRDRK 2.5 – 60Three-phase compact rectifier transformersStandard version:with a downstream three-phase bridge rectifier,Input 3AC 380/400/420V, output DC 24V, residual ripple < 5%Capacitor design:with a downstream three-phase bridge rectifier and capacitorInput 3AC 380/400/420V, output DC 24V, residual ripple < 2% General:The RDRK series has been specifically developed for use with programmable logic controllers (PLCs). The transformers are very well-sized and voltage-stable. This results in a particularly flat characteristic curve between no-load and load conditions, ensuring that overvoltages or undervoltages critical for PLCs do not occur, even during significant mains fluctuations.The rectifiers are protected against short-term current surges and voltage spikes.The protective circuitry for the capacitor version is provided by a protection board containing the corresponding varistor, film capacitor, and discharge resistor.Configuration:Open, upright design, stationary, for equipment installation and mounting in dry rooms, isolated windings, all connections via creepage-current-proof screw terminal blocks. The terminals are protected against contact by the back of the hand and fingers in accordance with UVV (BGV A3).IP 00, insulation class E, max. ambient temperature 40°C (ta40°C/E)For versions with a capacitor, the dimensions change slightly. The mounting dimensions remain unchanged.Other versions available upon request (fuses, voltages, connections, etc.) Insulation class E
