Unregulated Power Supplies
An unregulated power supply does not contain any form of regulating circuitry. Output load ‘regulation’ is determined by the inherent transformer impedance and circuit resistance. Output line ‘regulation’ is directly proportional to the AC input change. Unregulated power supplies are adequate for non-critical loads such as relays, solenoids, and lamps and are a lower cost alternative to regulated supplies.
Typical applications
General purpose use - including, but not limited to:
- relays
- solenoids
- lamps
- actuators
- anywhere that good regulation and/or low ripple is not required
