Isoled Electronic transformer input 220-240V AC output 11.5V AC 0-105VA dimmable housing material: plastic/blue rated voltage/current: 230V AC apparent power in VA: 105 protection class: IP20 dimmable: yes dimming specifications for a connected load from 30VA:phase control: 20 - 100% standard dimming. er: 15-1 00% Universal dimmer: 15 - 100% With connected loads below 30VA, the dimming range is reduced! Special features including over-temperature fuse (not resetting), when using AC voltage transformers, the apparent power of the connected load must be taken into account for the correct power measurement. If the transformer is dimmed, the reactive power of the connected consumers can multiply. Note: apparent power and transformer design for LED bulbs at 12 V AC voltage To maintain the life of the LED bulbs and transformers, it is of crucial importance to deal with the apparent power of the LED bulbs. Undesirable reactive power LED bulbs are generally not ideal ohmic consumers, but show capacitive or inductive load behaviour depending on the design. This results in a phase shift and an undesired reactive power is created in addition to the rated power (= active power) when operating with AC voltage, which is indicated in VAr (formerly reactive watts bW). Reactive and active (= nominal) power becomes apparent power. The apparent power is calculated from this reactive power and the rated power. The apparent power is indicated in VA and can therefore be easily matched with the power specifications on AC voltage transformers, which are also listed in VA. Note: Private or small consumers do not have to pay for the additional reactive power of a light bulb to the energy supplier. The costs incurred for the necessary expansion of the cable network (as more and more reactive power occurs in the public network) are divided among all customers or charged only to the biggest causes of reactive power (industrial companies or solar power feeders).
