Description:

 PowerRack LT2 switch mode (IGBT) rectifier, air cooled:

  • < 3% ripple through full output range for consistent process results
  • Highest quality components
  • System expertly engineered for long service life
  • High efficiency and power factor through full output range
  • Smaller and lighter than SCR rectifiers
  • 100% duty cycle (rated for 100% output 24/7)
  • Up to six modules operating in parallel to achieve specified current outputs
  • Fewer, large capacity modules (up to 25kW each) versus competitive systems for higher reliability
  • 25kW up to 150kW (up to 9000A total, depending on VDC) maximum output power
  • Automatic load sharing between the power modules and integrated EMC filters
  • If one module fails, rectifier continues operating at reduced output
  • Corrosion resistant, e-coat primer with powder coat top coat, steel cabinet
  • Each module also housed in individual powder coated enclosures for maximum corrosion protection
  • Easy maintenance access through the front door
  • 19” slide rack modules for quick replacement if needed
  • All power module connections in the front for easy access
  • Steel base and removable side panels
  • Input power and control cables enter from the top
  • DC output through copper bus bars in the back
  • Galvanic isolation between AC input and DC output
  • All copper internal power contactors and transformer for high efficiency
  • Analog interface (0-10Vdc) for remote control

Air cooling system:

  • Cooling air flow: inlets on the sides, into the front of each module, and exhaust out the rear of the enclosure
  • Minimal cooling air required: quiet, variable speed, thermostatically controlled fans
  • Air is directed only to heat sinks cooling the power components
  • All sensitive electronics isolated from the cooling air
  • Conformal coated circuit boards for additional corrosion protection
  • Thoughtful design ensures exceptional service life

Main Components:

  • Front door circuit breaker with lock out handle
  • Input contactor
  • EMC filter to minimize noise to the power grid
  • Fully electronic current and voltage control adjustable from 1% to 100% with wear-free
  • power semiconductors

Protection Devices:

  • Ultra-fast electronic DC over-current limitation
  • DC short-circuit current limitation
  • Over-temperature protection (with indication through potential-free contact)

Controls Interface:

  • Set-point adjustment for Volts & Amps: 0-10 Vdc
  • Actual feedback values for Volts & Amps: 0-10 Vdc
  • Rectifier On/Off (customer terminal Input)
  • Rectifier running (customer terminal Input)
  • Rectifier fault (customer terminal Input)
