No, the different types of 12V switching adaptor have different amperage. LACTOSCAN Thermostatic devices must be used only with the 12 V switching adaptor with 3A amperage which included in the set. If you use it with another 12V switching adaptor, for example, with 2A amperage, the switching adaptor won’t be able to supply the device, the protection of the switching adaptor will activate and the thermostatic device won’t switch on.
