USEFUL HELPERS Car System E Accessories, engineering E Useful helpers 163730 Step-up transformer (0.8 to 3.3 V) Compact electronic circuit using an input voltage in the range of 0.8 to 3.3 V to generate a constant 3.3 V output voltage. Module allows to operate e.g. LEDs in Car System vehicles running on one rechargeable battery cell (1.2 V) only. Its outputs are fitted with suitable protective resistors so that SMD LEDs Art. 163750, Art. 163751, Art. 163752, and Art. 163753 can directly be connec- ted. Analogue Car System truck models can be equipped with lighting when combined with »Step-up transformer (0.8 to 3.3 V)«, Art. 163730. Suitable products are, for example, ∙ Car System Digital, LED Trailer light bar, Art. 163758 ∙ Car System Digital LED Lighting kit for lorry MB SK, F2000, Art. 163759 ∙ 5 SMD-LEDs, white, Art. 163750 ∙ 5 SMD-LEDs, blue, Art. 163751 ∙ 5 SMD-LEDs, red, Art. 163752 ∙ 5 SMD-LEDs, orange, Art. 163753 40 161352 (H0, N) Expansion module The expansion module is connected to the basic module (interface) per LocoNet, to have more inputs and outputs for stop sections, branch-off junctions, traffic lights, lighting, sensors and parking spaces for more complex model layouts. Several expansion modules can be connected in series. 11 inputs for sensors, 12 outputs for operational elements. 180641 (H0, TT, N, Z) Transformer Transformer for high output. Especially applicable for the operation of fair rides, electrical appliances, lighting, power supply for Car System controls and other model making acces- sories. With overload protection. 16 V, AC voltage 3.15 A 12 V, DC voltage 0.6 A (controlled) 5 V, DC voltage 0.6 A (controlled) 147 x 84 x 64 mm 180633 (H0, N) Rectifier Rectifier to transform 16 V alternating current into direct current. Especially applicable for LED lighting in order to avoid a slight flickering of the small bulbs (art. 180647, 180648, 180649 as well as the lights 180630 + 180633).
