BLOCK FL 18/14014/9 变压器

9 V ac, ±14 V ac 2 Output Through Hole PCB Transformer, 18VA

Block

PCB Mount Transformer, Triple Output, 115/230Vac High quality, low profile, triple output encapsulated safety isolating transformers with twin 115Va.c. 50/60Hz primary windings which may be connected in series for 230Va.c. or parallel for 115Va.c. operation. These transformers are designed for use in 5V and ±12Vd.c. power supplies when used in conjunction with readily available bridge rectifiers and regulators. Designed for through hole soldering direct to PCB's; mechanical fixing can be supplemented by 4 self-tapping screws (No.4 x 9.5 mm max. on the 6VA to 30VA transformers and M3 on the 45VA transformers) using holes moulded into the corners of the case. Low profile compact designDouble section glass fibre reinforced polyamide bobbins5kV primary/secondary isolation100% electrical and flash testedHigh efficiency and low temperature riseLow inter-winding capacitanceLow radiated noiseExtra fixing holes for secure board mountingHigh quality manufacture and testing in accordance to VDE 0570, EN 61558 Selection Guide VA Rating Fixing centres (mm)   Pin configuration (mm)           C1 C2 P1 P2 S1 S2 A 6 37.5 47.5 15 10 20 5 35 10 50 62.5 15 15 30 5 45 14 50 62.5 15 15 30 5 45 18 50 62.5 15 15 30 5 45 30 50 62.5 15 15 30 5 45 45 60 75 27 15 32 10 53.5 Technical specification Full load output voltage Secondary 1: 9Vac   Secondary 2: 14.5-0-14.5Vac Typical regulator types Secondary 1: 7805   Secondary 2: 317L 337LZ Isolation Primary to Secondary 5kV   Primary to Primary 1kV   Secondary to Secondary 250V Protection Class 2 Insulation Class E (120°C) Operating temperature +40°C ambient max.
