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 ?

REGULATED POWER SUPPLY (RPSU) vs SWITCH MODE POWER SUPPLY (SMPS)

GENERAL SMPS RSPU
Efficiency 65 – 85% 25 – 50%
Ripple 20 – 50 mV p-p 5nV p-p
Temperature 20 – 40 c 50 – 100 c
Regulation 0.3% 0.1% or better
Weight 65 w/lb 22 w/lb
Volume 1 cu in/w 2 to 3 cu in/w
Isolation from Transients Very good Inferior, noisy lines
RFI/EMI Troublesome Less likely
Magnetics Small design Bulky
Reliability Better to cooler operation Higher temp., makes poorer
Cost More, but trend is decreasing Less for smaller ranges,Test MOSFET
