Rectifiers - CB



The energy stations (RECTIFIERS-BATTERY CHARGERS) of the SE1R (Single Branch) series are electronic equipment for industrial use, expressly designed to supply direct current users without interruption. Sturdy, reliable and particularly accurate to comply with current regulations, they essentially consist of a stabilized / filtered rectifier and a control circuit, all to keep the battery charged and ensure power supply to users in the presence / absence of the network. The SE1R energy stations are available in three circuit configurations: - RT: single buffer branch (T) - RC: single branch with drop cells (C) - RS: single branch with series regulator (S).

  • Single branch configuration
  • DC output voltages 24V, 48V, 110V, 220V
  • SCR technology (high reliability)
  • Housing in metal floor cabinets
  • High degree of customization
  • Standard / Forced natural ventilation
  • RT = Single Branch Battery Backup
  • RC = Single Branch with Drop Cells
  • RS = Single Branch with Series Regulator
  • Visualization of functions on digital display / Analogue or digital instrumentation
  • Quick charge and optional manual
  • Voltage free alarms, in terminal board


The energy stations (RECTIFIERS-BATTERY CHARGERS) of the SE2R (Double Branch) series are electronic equipment for industrial use, expressly designed to supply direct current users without interruption. Sturdy, reliable and particularly accurate to comply with current regulations, they essentially consist of two stabilized / filtered rectifiers and their respective control circuits, all to keep the battery charged and ensure power to the user.

  • Double branch configuration
  • Stabilized output voltages
  • SCR technology (high reliability)
  • Housing in metal floor cabinets
  • High degree of customization
  • High short circuit resistance
  • Standard / Forced natural ventilation
  • The battery branch is configurable for hot redundancy
  • Visualization of functions on digital display / Analogue or digital instrumentation
  • Quick charge and optional manual
  • Voltage free alarms, in terminal board


The main elements of MEDEL's SEsw systems are represented by the AC / DC conversion modules made in switching technology. They are available in various voltage and power cuts, and are typically connected in parallel to ensure maximum reliability with n + x redundancy or simply to achieve higher output currents. Designed to work in conjunction with the batteries, providing a seamless DC power source, each module can be hot swapped without the need for downtime. The low noise level introduced and the high reliability make them ideal for all critical applications such as TLC, emergency auxiliary systems, video surveillance, etc.

  • Ideal for critical TLC applications.
  • Modular and scalable
  • Designed for redundant operation (n + x)
  • High efficiency
  • Hot swap module replacement
  • Centralized control logic
  • Available in standard and custom configurations
  • Low harmonic distortion THDi <5%
  • Distribution installable on board
  • Available with the following interfaces: RS232, free contacts, TCP / IP-WEB-SNMP, modem (GSM / GPRS or telephone line)
  • Multifunction display
