Regulated Power Supply 0-30V Price and Specifications

O-30V DC SINGLE  Or DUAL TYPE VARIABLE POWER SUPPLY.
When the selection of power supply specifications, the following questions must be need:
rpsu1

  1.  How much current does the system require
  2.  How much ripple voltage can be tolerated?
  3.  How much voltage drift with temperature is acceptable?
  4.  Do we use one lager regulator or many individual regulators to match the various load ?
