The BLOCK PT 4.5/2/9 is a compact, safety‑isolating transformer designed for PCB mounting, delivering dual secondary outputs of 9 V AC (2 × 9 V) with a total power rating of 4.5 VA. It features an encapsulated design with PTC overload protection and is ideal for SELV/PELV circuits in control systems, instrumentation, and industrial power‑management applications. Due to its safety‑isolation characteristics, this transformer is suitable for providing SELV/PELV outputs in control cabinets, measurement modules, and signage systems.

Standout Features and Benefits of the Block Hole PCB Transformer

Dual secondary output (2 × 9 V AC) offering flexibility for series/parallel connection.
4.5 VA power rating supports modest loads without a large footprint.
Through‑hole PCB mounting, with additional screw‑fixing holes for secure board installation.
Encapsulated in self‑extinguishing resin (UL94‑V0) with XtraDenseFill technology for corrosion protection and high insulation.
Integrated PTC protection in the primary winding ensures overload and short‑circuit robustness.
Compliant with EN 61558‑2‑6, UL 5085‑1/−2, and VDE safety transformer standards.

Optimised Performance for Control & Instrumentation

With dual 9 V secondary windings, the PT 4.5/2/9 allows designers to create isolated power rails or to connect the secondaries in serial for higher voltage or in parallel for increased current. Encapsulation and PTC protection reduce board space while enhancing reliability in demanding industrial environments.

Broad Range Application

Isolated power supply for control‑panel electronics, instrumentation and interface modules
SELV/PELV circuits requiring dual 9 V AC rails or series/parallel secondary connection
Through‑hole PCB integration in industrial automation boards and OEM assemblies
Low‑power AC signal supply for drive modules or sensor interface circuits
Retrofit or replacement applications where safety isolation and compact footprint are required
Power‑managed modules in communication, measurement, and monitoring systems
