MICHAEL RIEDEL RDRKL 16K/27S THREE-PHASE ISOLATION TRANSFORMER WITH RECTIFIER UNIT P/N 11271283, 0.432KW

MICHAEL RIEDEL RDRKL 16K/27S is a German-made 3-phase transformer + rectifier integrated power supply unit from RDRKL series, part number 11271283, rated power 0.432kW, designed for PLC and marine low-voltage control system power supply. The transformer unit accepts 3-phase AC input 3×380/400/420V 50/60Hz, converts AC voltage and rectifies to stable 24VDC output with ripple less than 2%. The transformer unit integrates built-in bridge rectifier and capacitor smoothing circuit, delivering steady 24VDC logic power for automation I/O modules, controllers, alarm panels and marine console electronics. The transformer unit adopts separate primary and secondary winding isolation design, integrating varistor surge protection circuit to suppress voltage spikes and transient noise from ship power grid. The transformer unit maintains flat voltage regulation curve under light and heavy load variation, avoiding accidental system reset caused by grid fluctuation.

MICHAEL RIEDEL RDRKL 16K/27S adopts open frame horizontal metal mounting structure for installation inside low voltage control cabinets. The 3 phase power supply module complies with EN61558 / VDE0570 safety standard, CAGE CLAMP vibration-proof screw terminals, ideal for marine and industrial vibration environments. The 3 phase power supply module has IP20 protection rating, insulation class E. The 3 phase power supply module features low heat generation and long service life; built-in surge absorption circuit protects downstream PLC and I/O hardware against power transients. The 3 phase power supply module is a reliable spare component for retrofitting marine engine control, machinery alarm and unattended machinery space automation systems.

MICHAEL RIEDEL RDRKL 16K/27S is widely deployed on cargo ships, tankers and offshore vessels to supply stabilized 24VDC control power for marine automation, PLC and alarm monitoring systems. The industrial spare part can replace defective transformer rectifier units to restore isolated 24VDC stable power supply rapidly. The industrial spare part matches original mechanical mounting dimensions and wiring terminals for direct cabinet replacement. The industrial spare part has clear part marking for fast identification and stock management. The industrial spare part reduces vessel downtime during control cabinet overhaul and marine survey inspection.
