SI24 3U (24V / 20-40A)

The SI24 Series power system are based on hot plug rectifiers. They have been designed for powering the 24 V DC loads with uninterruptible current of up to 20, 30 and 40A respectively in a system with a common positive rail.

The system provides direct floating operation (rectifier units and powered devices are connected with uninterruptible battery banks in parallel).

All the connections of the power systems are made on the back panel, but the entire service process, including exchange of fuses, is possible on the front panel. In the device you can install up to four rectifiers.

 

  • professional telecommunications (telephone exchanges and access systems)
  • subscriber telecommunications
  • industrial automation systems
  • precise maintenance of floating operation voltage - dependence on temperature
  • battery bulk charging with charging current limitation
  • low and high battery voltage control
  • battery continuity check and LVDD
  • overload control of outputs
  • full control of device correct operation
  • optical, audible and remote signalization
  • digital measurement of voltage, current and temperature
  • input for two external alarms
  • record of event history in non-volatile memory
  • cooperation with computer software
  • communication via RS-232 or RS-485
  • cooperation with external communication modules
