Frequently asked questions
What is the ADC used for?
It controls single-phase and three-phase motors directly — ideal for high-power hoists where the pendant switches the motor current itself.
How many buttons does it have?
Three: one twist-to-release emergency stop and two direction push buttons, with 2 directions mechanically interlocked.
What is the rated current?
Rated thermal current (Ith) is 25 A at a rated insulation voltage (Ui) of 500 V.
What switching capacity does it offer?
1-phase/2-pole 230…400 V AC — 2.2 kW; 3-phase/3-pole 230…400 V AC — 4 kW.
Is there an emergency stop?
Yes — a Ø30 mushroom emergency stop, turn to release (EN ISO 13850).
What protection class does it offer?
IP65 with a double-insulated ABS enclosure.
Which versions are available?
ADC3, ADC3.RG, ADC3.GE (1-speed) and ADC3D2 (two-speed); contact Konrak for other configurations.
