UBEK PowerSupply

Job Description:


I need to have a power supply system designed. Please see Mauch electronic as an example (shown below), but have distanced differences. Each voltage must consist of three individual PSUs with their outputs combined. Each individual PSU must deliver the design voltage @ 10A continuously and with short bursts @15A and current cut-off @ 20A PSU based on LM5116 reference design Output files in Altium format Requirements Input voltage 13.5V - 60.0V Supply from two input sources. Inputs must be isolated. Supply voltage from input 1 must NOT flow out input 2 Output voltages options – each output consist of one Molex P6 5.3v 2x Molex P6 + 1x Molex P4 Fan connector (three individual PSUs combined) 7.4v 2x Molex P6 (three individual PSUs combined) 12v 2x Molex P6 (three individual PSUs combined) 24v 1x Molex P6 (three individual PSUs combined) Dual (redundant) 100V linear voltage regulators for FET driver and digital circuit per PSU. The power supply (each voltage) is fully redundant (merge 2 separate units) 5.3v Connector for cooling fan Power ON / LED for each power supply Soft start to ensure proper power up from GND. Output ripple voltage maximum 0.005V @5A. Outputs are rated with a continuous current of 10A with short bursts @15A (current cut-off 20A). Output includes independent under-voltage protection (13.5V) Overvoltage feedback loop for all outputs. Oversized FET in the input stage. -> Nearly spark-free connection. Control/power switch option. If no switch is connected unit must auto-power after 2-5 seconds If the digital part fails, then the unit must arm itself within 3 sec. This emergency power on the circuit must run parallel to the main control and be fully independent. Once armed, it can be only disarmed with a positive signal from the switch above 1500us. Please provide a price estimate for producing a schematic.
