Model VB 3.2/2/12
Description Installation of transformer printed circuit board, short circuit protection, VB and PT series 230V AC 50 to 60Hz primary winding single or double secondary winding, used for series or parallel connection (for safety compliance reasons, 0.35 to 3.2VA transformers with 2 x 15 and 2 x 18V outputs, as well as all transformers with 2 x 24V outputs, should not have their secondary windings connected in series, as this means they will not comply with VDE 0550 certification) VB series (0.35-3.2VA) inherent short circuit protection PT series (4.5-22VA) is provided by internal PTC equipment with a compact design vacuum epoxy resin molding, achieving UL94-V0 level dual load surface glass fiber reinforced polyamide wire spool 100% electrical and insulation test high efficiency and low temperature rise, low capacitance between windings, low radiation noise additional fixing holes, ensuring protection at 4.5VA Installation and fastening selection guide for upper plates of transformers and higher (double secondary) - VA Rated value | Fixed center (mm) | | Pin configuration (mm) | | | | C1 | C2 | P1 | S1 | S2 | A | Pin size 0.35 | - | - | 15 | 5 | 5 | 15 | 0.6 Ø 0.5 | - | 15 | 5 | 5 | 15 | 0.6 Ø 1.0 | - | - | 20 | 10 | 20 | 0.8 Ø 1.5 | - | 20 | 10 | 5 | 20 | 5 | 20 | 5 | 0.8 Ø 2.3 | - | - | 20 | 10 | 5 | 20 | 0.8 Ø 3.2 | - | - | 20 | 10 | 25 | 0.8 Ø 4.5 | 35 | 28 | 25 | 15 | 5 | 25 | 0.8 Ø 7.5 | 40 | 32 | 25 | 15 | 5 | 27.5 | 0.8 Ø 13 | 47.5 | 37.5 | 30 | 20 | 5 | 30 | 0.8 Ø 22 | 52.5 | 40 | 30 | 10 | 32.5 | 0.8 Ø Isolation | | Primary to Secondary 5kV Secondary to Secondary 250V -------------------- | Protection Level | 2 Insulation: | VB Series PT Series | B Class (130 ° C) A Class (105 ° C) E Class (120 ° C) A Class (105 ° C) Fixed: Strengthen the mechanical fixation of 4.5 to 22VA transformers by using 4 self tapping screws (maximum size 4 x 9.5mm) and fixing holes at the corners of the box. || Maximum ambient temperature | 0.35 to 2.3VA+70 ° C, 3.2VA+50 ° C, 4.5 to 22VA+40 ° C | Selection guide (single secondary) - VA ratin
