Double drive

Two adjustment drives and all control functions are fitted into a single casing. DUOMAT double drives represent the most cost-effective solution for the individual adjustment of head ends and foot/knee ends in motorised beds and mattress surfaces. Thanks to their “all-inclusive” design, double drives can be fitted in next to no time. If additional adjustment functions are needed, more single drives can be connected to TRIOMAT or QUADROMAT drives.


Duty cycle

This technical factor defines the maximum period of time during which a drive can be operated without interruption. A pre-set currentless time must also be maintained following operation. 
Both time values are shown as a ratio which indicates the duty cycle data. A factor of “2/18 minutes” is now standard in the furniture sector – this means that a 2-minute period of uninterrupted operation must be followed by a break of 18 minutes. 
Of course, in the event of operation for a shorter period of time, the break can be correspondingly shorter. It is vital for the operator to follow the instructions regarding the duty cycle, otherwise possible overloading might result in the activation of the protective devices.
