PRECAUTIONS
SAFETY
AC power supplies are sources of high voltage. Improper or careless use could result in fatal
electrical shock. Observe common sense safety precautions when using this and other electronic
devices.
INPUT POWER
These instruments are intended for use with 120V, 60Hz line voltage. Do not operate with 50Hz
line voltages, or 220~240VAC volt power systems. The instrument may be operated safely with
line voltages as low as 100V, but note the maximum output voltage will be lower.
VENTILATION
The louvered holes in the case provide cooling. Do not block these holes or locate this device
near heat sources. Excessive temperature buildup inside the unit can cause failure and a
potential hazard.
MAXIMUM OUTPUT VOLTAGE
The output voltage of the AC power supply is adjustable from 0 to 150VAC. It should be noted
that this is higher than the maximum recommended input voltage of most electronic devices. The
voltage setting of this unit should not exceed the device manufacturer ratings as potential
damage could occur. Most AC powered equipment has a maximum input rating of 130VAC. If
unsure of the maximum AC voltage rating, do not exceed 130VAC.
MAXIMUM OUTPUT CURRENT
Never exceed the maximum output current of this unit. Excessive current loads will damage the
variable auto transformer and isolation transformer.
ISOLATED OUTPUT
The isolated output should only be used for equipment under test. Other test instruments should
not be connected to this output.
Fuses
Use only the recommended fuse value for the Line Fuse. When replacing this fuse, be sure to
use AGC style fast blow type. Disconnect the input power cord from the AC source prior to
attempting to remove and replace this fuse.
The Output Fuse may be replaced with a lower value in order to provide current limiting
protection to the device under test. It is important to note that lower values should still be AGC
style fast blow type. Never replace this fuse with one of larger value than listed on the front panel
of the Isolated Variable Power Supply. Disconnect the input power cord from the AC source prior
to attempting to remove and replace this fuse.
