PFC MegaPAC Mpaa-7bcccc-v-xx
p = P for standard chassis. p = X for high power chassis aa = number of outputs
b = number of DC-DC modules and FlexPACs cccccc = customer specific configuration code
v = optional revision code and may be blank. (note: v = G for RoHS compatible product)
xx = additional option codes
note: xx = MI for rugged chassis, = MC for rugged chassis with conformal coating

P Preload
1
D option: Optional for all ConverterPACs EXCEPT the DualPAC, BatPAC and RamPAC
2
F options: Optional for all ConverterPACs EXCEPT the BatPAC, DualQPAC, and FlexPAC. Trim range dependent on
module type and voltage
3
Ram: When using an external RAM, components such as autosense resistors and local sense jumpers must be removed
before turning on the supply. In addition, in order to insure proper operation, sense pins must be connected either locally or
remotely after the RAM's output. For further information, contact Applications Engineering.
4
T options: Optional for all ConverterPACs EXCEPT the BatPAC, DualQPAC, and FlexPAC. Trim Range dependent on mod-
ule type and voltage
5
V options: Optional ONLY on the ModuPAC, DualPAC and JuniorPAC. N/A on all other ConverterPACs. Requires 15%
minimum load
