50 amp rectifier

Product Information

The SAGEON® Micro 48V Series 50 amp rectifier is a switched-mode module designed to provide up to 50A of output current into a 48VDC nominal system.

This rectifier is available in 6A, 12.5A, 25A, 34A and 50A models and has been designed to be used in conjunction with a battery to provide an uninterruptable DC power system. The low noise and high reliability mean that the Sageon Micro 50 amp rectifier is ideally suited to  telecommunications applications.

From 1 to 27 50 amp rectifiers can be configured as a system using one control and supervisory unit (SAGEON® Plant Controller).

The system can be monitored and controlled remotely using SageView® software.

Current Limit20% -120% of Rated Output
Power Limit Current limit is automatically reduced in direct proportion to input voltage and in inverse proportion to output voltage
Line RegulationBetter than ± 0.05%
Load RegulationTerminal voltage drops by 0.42V ± 0.03V from zero to full load (for passive current sharing) for stand alone units, or regulates to better than ±0.05% for SAGEON® Controller controlled units
Dynamic Regulation± 2% for 10% to 90% to 10% step load change, ± 1% of final value within 1ms of step change, ± 0.2% for a 25% step change in AC input voltage
Noise< 0.96mV RMS Psophometrically weighted, < 32dBrnC, < 10mV RMS (10kHz – 100MHz),< 100mV peak to peak (10kHz – 100MHz
Load SharingBetter than ± 5% of full scale with active current sharing from the SAGEON® Controller
Protection Fusing – protects against reverse polarity connection and protects DC bus if internal components fail; Hot pluggable – no surge when connection is made to a live DC bus; Overvoltage – only faulty unit shuts down; Overcurrent – can sustain short circuit at output terminals indefinitely; Over-temperature – gradual reduction of power limit if heatsink temperature exceeds pre-set limit. Supplementary thermal overload production is provided
Voltage Withstand Test 1000 VAC output to chassis for one minute (1500VDC 100% testing on production units for 2 seconds)
