Product Description

Block PT 4.5/2/12 is a 12 V AC PCB Transformer designed with two independent secondary outputs delivering a total power of 4.5 VA. It is engineered for through hole PCB mounting, ideal for compact electronic power supply applications.

This transformer operates at a primary voltage of 230 V AC, suitable for common mains power input. The device features a single primary and dual secondary winding type, allowing for series or parallel connections as per design requirements.

Its compact dimensions of 44 mm length, 33 mm width, and 37 mm depth, combined with a weight of 190 grams, provide easy integration into PCB layouts without excessive space consumption.

The PT series transformers incorporate internal PTC devices for short circuit protection and are vacuum epoxy resin moulded, achieving UL94-V0 fire retardant rating. The use of double section glass fibre reinforced polyamide bobbins enhances mechanical strength.

Operating within a frequency range of 50 Hz to 60 Hz and maximum temperature of 40°C, this transformer ensures reliable and efficient performance, boasting 65% efficiency and low temperature rise during operation. It is certified to UL and VDE standards, attesting to its safety and quality compliance.

Additional features include low inter-winding capacitance to reduce noise, low radiated electromagnetic interference, and extra fixing holes for secure mounting on PCBs especially for 4.5 VA and above models.

Primary voltage: 230 V AC. Secondary voltage: 12 V AC with 2 outputs. Power rating: 4.5 VA. Mount type: Through hole for PCB. Standards: UL and VDE certified. Compact size: 44x33x37 mm (LxWxD). Weight: 190 grams. Efficiency: 65%.

Operating frequency: 50-60 Hz. Max operating temperature: 40°C.

This transformer is suitable for electronic components, power supplies, and transformer applications requiring reliable low power AC voltage transformation on PCBs. It supports industrial, laboratory, manufacturing, and HVAC control systems demanding UL and VDE compliant toroidal transformers.
