Type:
Transformer & rectifier
Application:
For the power switch from high voltage AC to DC in electro-refining workshop and providing a stable current inside the electrolyte tank.
The Switch-mode DC power supply is a solid state AC to DC power conversion system. The system functions by first rectifying the AC input to an unregulated DC voltage, this intermediate DC voltage is then switched using pulse width modulation through a full-bridge converter into a high frequency transformer. The output of the transformer is rectified and filtered to provide a precisely controlled high current DC output with <2% AC Vrms content. The high switching frequency enables smaller magnetics and filters, less ripple and higher efficiency and provides for a faster control loop.

Modular Design
Any combination of power modules up to 200 VDC or 20 000A can be supplied. The rectifiers consist of 1–10 power modules. Together with a control module, they form a complete power supply.
Serviceable
Easy access to modules for repair or replacement.
High Power Factor
Low reactive power consumption throughout the whole range.
Ripple
Low ripple at all output currents.
Fault Diagnosis
The power supply features a fault diagnosing protection system to automatically shut down the unit in the unexpected event that an over-temperature or an IGBT fault condition exists. If a fault is detected, the microprocessor first verifies the fault and attempts to correct the condition. If the fault continues, the power supply will shut down.
