What is the fuse rating on the main power supply assembly in the 33220A Function/Arbitrary Waveform Generator?Description
The main power supply provides an input fuse (type UL/IEC127, rated 250VAC H 3.15A) to protect against the danger of fire in the event of a failure of the power supply circuitry. However, this fuse will not fail ("open" or "blow") in normal power supply operation. The fuse fails only in the event of a significant overload indicating a failure of the power supply circuitry. Replace the entire main power supply assembly if the input fuse fails. Note that a power supply failure may be caused by a failure elsewhere in the instrument.
