Purpose: Provide multichannel power for VMM FEE and Readout Boards 

Ratings and Specifications:

Power Total:         200 W / 8 Channel Board
Current / channel: Maximum 2.5 A (30W)
Voltage Output:    Adjustable from 6.0V to 12.0 V out

Ripple:               

 < 1.0% at full load ( Bandwidth >20Mhz),
 < 0.5% ripple (20MHz)

Regulation:          < 1.0 %
Output Impedance: 0.20 ohms
 

Over-Voltage Protection: TVS crowbar  > 12.0 V
Over-Current Protection: Output Fuse 2.0A

Form Factor: 6u PCIe board/ DEP power system crate

Recovery Time (transient stability): Output settles to within +/- 0.5% steady state with 10% or greater change in load current

Operating Temperature: (operating environment): 0 deg. C to 50 deg. C with negligible derating
50 deg. C to 60 deg. C PSU will de-rate ~ 5.0%

Temperature Coefficient: Output Voltage change ~ 0.03% / deg. C
 
Thermal Protection: 

Each 8 channel power board is monitored with a board mounted temperature sensor from the crate controller

The individual DC/DC modules will drop output Voltage if the regulators temperature exceeds 80 deg. C

EMI: Shielded Module

Low far and near field emissions
negligible conductive EMI 

Form Factor:        6u PCIe board/ DEP power system crate
