To recharge any types of rechargeable batteries, for instance vented or sealed,lead-acid,Ni-Cd, the three-phase rectifiers, empoly a 6-pulse thyristor bridge, fully controlled by PCB board.

Limit the output by dropping Diodes
Isolation transformer and Harmonic filters
Applicable international standard:IEC 60950-1
Panel IP and panel thickness:IP20 Indoor,2mm
Rectifier efficiency:≥90%
AC&DC short circuit current:TBD based on design and below specs.
Mode of controlling output voltage current specify it should be manual /automatic:Both(Manual & Automatic,but the output voltage should be regulated.
Rectifier transformer overload capacity:The Max.rectifier capacity
Type of metering indicators:Both (Analog &Digital)
Installation type:Indoor
Type of Earthing:Solidly
Input:-
3 phase AC Supply 400VAC±20%
50Hz±6%
Power Factor Approx(0.7-1)
Isolation transformer
Output:-
110VDC Regulated with ± 5% (Adjustable)
0-100A
DC Filter
Output Ripple voltage Max 5%rms nominal DC voltage
Charging Mode Selector Switch:
The charging mode should be Automatic and Manual with independently adjustable of charging via selector switch as:
Float (Trickle) Charge
Hi-Rate (Boost) Charge
Current Limit Setting
Float and boost Charge Rating capacity:Adjustable for the batteries with capacity of (100AH-600AH)
Slow-Start:
The Slow Start function is used to prevent high current surge during powering up of the rectifier and the Circuit only operate during the start-up of the rectifier.
Typically,the design is chosen to give the slow-start ramp of I0seconds from start up.
