DESCRIPTION

The CRS-2000 series consists of DC-DC converters with galvanic isolation between input and output. The converters operate at a fixed switching frequency and use full-bridge converter topology. For optimum regulation, remote sensing terminals must be connected on the load allowing to compensate for a voltage drop up to 0.3V on each cable. A current limiting circuit protects the PSU against overloads and short-circuits. The device is also protected against reverse polarity on input and the input fuse blows if an improper connection is made. Under input undervoltage condition the PSU is disabled to prevent excessive discharge on the battery. Once the input is within the range the unit restarts automatically. START-UP Cable connection should follow power and signal connection figures. Remote sensing is not mandatory, but if it is required, use of a co-axial or a twisted-pair cable is recommended. WARNING: If the load is connected to the tabs of remote sensing (+/-S) and the connection from the output to this load is missing the remote sensing function could be made unusable due to the acting of the internal fuse protection. If power levels close to the maximum are required, make sure the assembly enhances cooling by natural convection and the unit is placed in vertical position. If several converters need to be paralleled, do as follows:

  • Adjust output voltage of paralleled PSUs till they values match.
  • Join the load outputs by using cables with a cross-section no greater than the one required and of equal length.
  • Connect both output loads using cable with proper cross- section area and equal length.
  • Do not use remote sensing. For safety reasons, provide the equipment with a protective enclosure that complies with the electrical safety directives in effect within the country where the equipment is installed. INSTALLATION It is possible to install the unit by means of the threaded holes on the bottom or using mounting brackets, see accessories section. The inlet and outlet air must be free of elements that cause an airflow reduction (the minimum recommended distance to other objects is 50mm). It is necessary to consider the environmental conditions of maximum temperature and altitude since they can limit the maximum output power. See cabling recommendation below. LEDs The CRS-2000 is equipped with 4 LEDs that light up when:
  • Vin pres. → Control supply voltage OK
  • Vin OK → 70% < Input voltage < 125% of nominal
  • Vout OK → 90% < Output voltage < 115% of nominal
  • ORing OK → ORing circuitry is active ALARMS The alarm is activated when one of the following occurs:
  • 70% > Input voltage > 125% of nominal voltage
  • 90% > Output voltage > 115% of nominal voltage
  • There is a defective fan → LED Vin OK blinks at 2Hz
  • Internal temperature > 98°C → LED Vin OK blinks at ½Hz
  • ORing circuitry fails → LED ORing OK blinks at 2Hz and output turns off
