Power Supply
Technical Information
■
Selection of Wires
Wires for the Power Supply should must be carefully selected. Refer to this table when selecting the wires.
Recommended Maximum Current: The table is applicable to wires with 1 to 4 conductors. Keep the current value to within 80% of the values shown in this table when
using wires having 5 or more conductors. The following chart shows the voltage drop per meter in terms of the relationship between
the current and conductor diameter. Make sure that the current value does not exceed the recommended maximum current value.
Voltage Drop per Meter
(UL1015 Vinyl-sheathed Wires for Heat-resistant Equipment)
Note. The current indicates the allowable current. In practice, application must be below the recommended current values.
