State of the art switch mode technology PM2000 rectifier provides secure DC power in combination with a parallel battery, for supply of all types of DC consumers including constant voltage and current sources. The rectifier module is suitable for charging many types of batteries including: vented lead-acid, valve regulated lead-acid (VRLA) or nickel-cadmium batteries (NiCd). It can also be used as a direct power supply without batteries. The rectifier can be used in Protect MIP systems.
Output rating from single rectifier:
24 V DC; 50 A
After an EMI filter, the single phase mains AC voltage is boosted with a Power Factor Corrector to smoothed 400 V DC voltage. This allows it to achieve a power factor of > 0.99. From this, MOSFETs generate an AC voltage of 100 kHz. Through a transformer, the galvanic insulation and the voltage adjustment take place at the secondary side.
The high frequency AC voltage is then rectified by means of fast-acting diodes. An output filter is installed to reduce the voltage ripple. The output voltage and current are controlled by pulse width modulation of the transistor switch on the primary side.
