What is the part number for a potentiometer to control Schneider Electric Altivar variable speed drives (VSDs) ?
The recommended specification for potentiometers compatible across our range of drives (ATV11, ATV12, ATV31, ATV312, ATV21, ATV61 and ATV71 and the legacy ranges ATV15, ATV25, ATV452, ATV16, ATV66, ATV18, ATV28 and ATV58) is 2.2k Ohms. It is possible to use a value between 2.2k Ohms to 10k Ohms in certain instances.
Schneider Electric can supply two potentiometers of the optimum value of 2.2k Ohms;
2.2k Ohms - 3 Watts - IP65 - 9.5 mm cut-out
For use in dry environments on a wall-mounted or floor-standing enclosure.
This potentiometer's degree of protection means that it can be used on an enclosure exposed to humidity.
See dimensions and mounting below.
Harmony style potentiometer mounting adapters
Schneider Electric offers IP66 potentiometer mounting adapters that compliment the Harmony diameter 22mm offer.
Two versions are available for potentiometers with shaft length 45 to 50 mm long and either 6mm or 6.35mm diameter shaft.
ZB4BD192 (metal version) 6 mm diameter ZB5AD192 (plastic version) 6 mm diameter
ZB4BD922 (metal version) 6.35 mm diameter ZB5AD922 (plastic version) 6.35 mm diameter
Potentiometers to fit these adapters are not sold by Schneider Electric, they can easily be sourced at specialist distributors.
