Product Details

Transformers PCB Mount, Short Circuit Proof, VB & PT Series

230Va.c. 50 to 60Hz primary
Single or twin secondary windings for series or parallel connection (For conformance reasons,0.35 to 3.2VA transformers with 2 x 15 and 2 x 18V outputs and all transformers with 2x 24V outputs should not have their secondaries connected in series as this means they will not meet the VDE 0550 approval)
VB series (0.35 - 3.2VA) are inherently short circuit proof
PT series (4.5 - 22VA) are protected by internal PTC device
Compact design
Vacuum epoxy resin moulded to UL94-V0 rating
Double section glass fibre reinforced polyamide bobbins
100% electrical and flash tested
High efficiency and low temperature rise
Low inter-winding capacitance
Low radiated noise
Extra fixing holes for secure boarding mounting on 4.5VA and above
