IGBT POWER SUPPLY, 0 TO 22 VDC, 4500 AMPS, P/N 6137C2

Description:

MSA Tower switch mode (IGBT) rectifier, air-cooled:

• A modular “building block” design is easily expandable
• < 3% ripple through full output range for consistent process results
• High efficiency (>90%) and power factor through the full output range
• Smaller and lighter than SCR or power stat rectifiers
• 100% duty cycle (rated for 100% output 24/7)
• Corrosion resistant, e-coat primer with powder coat top coat, steel cabinet
• Steel base and removable side panels
• All connections are accessible from outside, making maintenance easy
• To remove/add a module: simply loosen the screw and cable connections (disassembly of
  module stack is not necessary)
• DC output through copper bus bars in the back
• All power conductors are made exclusively out of copper
• Current and voltage adjustable from 1% to 100% with wear-free power semiconductors
• Complete modular rectifier concept designed as a ready-to-go system
• Switch mode modules operated in parallel to achieve the specified output
• Each module is housed in an e-coat primed, powder-coated enclosure for maximum corrosion
  protection
• The design allows for quick and easy replacement of the modules if needed
• 0-10 V analog interface for automatic line control systems

Integrated power module features:

• The system consists of one control module, plus one to five power modules
• High efficiency, 19” rack mount switch mode power modules (up to 25kW each) operating
  in parallel
• Maximum of 5 modules, up to 125kW (up to 7500A depending on VDC)
• Maximum output voltage (depending on the model chosen) 45 VDC
• EMC filter to minimize EMC noise to the power grid
• Fully electronic current and voltage control loop
• High efficient control and rectification system with galvanic isolation between AC input and
  DC output

Air cooling system:

• Cooling airflow: 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 the exceptional service life

Main Components:

• A circuit breaker with an overcurrent trip function
• EMC filter to reduce noise back to the power grid
• Electronics for constant current and voltage control
• Power distribution panel

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 – 10Vdc
• Voltage feedback values: 0 – Volts actual: 0 – 10Vdc
• Current feedback values: 0 – Amps actual: 0 – 10Vdc
• On/Off via potential-free contact (Customer)
• Fault Feedback (Customer)
