Certified Europe: (CE) A mark applied to electronic
products (including some power
supplies) to be sold in Europe. The
mark certifies the power supplies
meet the applicable EMI/RFI and
safety directives.
Chassis: See Enclosure.
Chassis Ground: The voltage potential present
on the chassis, frame or enclosure surrounding
a power supply.
Charge Rate: The rate at which current is applied
to a battery cell to restore its capacity. Typically expressed
as ampere-hours or milliampere-hours.
Choke: See Inductor.
Choke Input Filter: A fi lter that uses an inductor
as its input component. Often used with a capacitor
(as an L/C filter), choke input filters offer improved
line regulation and are more resistant to input variations
than capacitor filters. See Input Line Filter,
Capacitive Input Filter, Common Mode Filter,
Pi Filter and Output Filter.
Chopper: See Inverter.
Circuit Breaker: A fuse like protection
device that opens when a circuit is overloaded.
Once tripped, circuit breakers can
be reset.
Circulating Current: See Ground
Loop.
Clamp Diode: A diode found in clipper or
clamp circuits. They are often used as part
of a power supply protection circuit.
