Switched modules HFM-A and HFM-D

advanced and intelligent systems that thrill you !

Description

Rectifiers of the HFM-x series are a combination of modern switching AC/DC converters and flexible 19" mechanical construction.

The advanced circuitry design provides a wide input voltage range, high efficiency, small dimensions and low weight. It is possible to order both types of the modules in a range from 24V to 220V and with the output current up to 200A.

A constant voltage and/or constant current control manages to correct the output voltage deviations that are caused by the input voltage or load transients within a very short time.

Optionally adding a gauge of the output voltage and/or a potentiometer for setting-up the output level for the module HFM-A.

A microprocessor unit (for the D-type module) with a 2-line display and 5 control keys on the front panel provides continuous monitoring of the input and output voltages, output current as well as all important temperatures and offers an easy adjustment and programming of the output parameters.

The RS232 serial interface (for the D-type module) allows monitoring of the output voltage and current and transmitting of all the parameters and measured values to a connected PC in real time. The connected PC can be used for the system setup and its control (option).

User interface - module D:

  • setup of all the operational parameters including alarms, communication parameters etc.
  • measurement of the output voltage, output current, battery temperature (optionally)
  • history of events with a time stamp
  • indication of the changed values and a logged user
  • user management - 3 levels of the access to the functions

Relay contacts - D-type module:

  • general failure
  • 6 configurable contacts standard setup:
    • remote switch-off 1 and 2
    • battery undervoltage
    • mains failure
    • summary failure
    • boost charging

Monitoring - both A-type and D-type modules:

  • output voltage high/low/delay
  • overcurrent/failure
  • battery temperature (optionally)

Communication:

  • D-type module - the RS232 interface for a link-up with a PC
  • A-type module - possibility of connection to the control system - module, eg. within the HFS system
