Substitution of Phaseo ABL8RP/WP power supplies by
Phaseo ABL4 power supplies
For the majority of applications, power supplies ABL4 easily replace power supply
models ABL8RP/WP due to:
v
the reduced size of the ABL4 (up to - 56% in volume),
v
tested compatibility with the function modules ABL8B/RED/8D/8P,
v
the presence of a diagnostics contact on all models,
v
a higher withstand to temporary overcurrents than the equivalent ABL8 RP/WP
power supplies.
However, for some applications the following points must be checked before
substituting ABL8RP/WP power supplies by ABL4 power supplies:

Standard IEC/EN 61000-3-2 defines the harmonic limits of the input current that can be
produced by equipment such as regulated switch mode power supplies ABL4 or ABL8. This
standard is only applicable to electrical or electronic devices that are intended for connection
to low voltage public distribution systems. This is rarely the case in industrial applications.
