LQ-D041144H Small Laminated Core Transformer 240V Primary 28.8V Secondary Leads

LQ-D041144H Small Laminated Core Transformer 240V Primary 28.8V Secondary Leads

The LQ-D041144H is a compact single-phase EI laminated core step-down transformer rated for a 240V AC primary input and a 28.8V AC secondary output. It uses a traditional laminated silicon-steel EI core construction with a yellow bobbin-wound coil and flying wire leads — red for the primary winding and blue for the secondary — making it straightforward to integrate into a custom chassis or PCB-supported mounting arrangement. Mounting brackets are built into the frame on both ends.

Applications

Small EI laminated core transformers like the LQ-D041144H are widely used in low-power electronics, control panels, instrumentation, and embedded power supply circuits where a fixed step-down voltage is needed from a 240V mains supply. The 28.8V AC secondary output is suited for driving rectifier-filter circuits to produce a regulated DC rail in the 24–28V range — a common voltage for industrial controls, relay coils, sensor circuits, and light-duty power supply designs. The chassis-mount bracket design makes these transformers easy to bolt into enclosures or onto DIN-rail-mounted panels. This type of open-frame construction is typical of OEM and custom-built equipment where the transformer is integrated as a sub-component rather than used as a standalone unit. The flying-lead termination style accommodates point-to-point wiring and small terminal blocks. These are standard components in industrial automation controls, custom power conversion assemblies, and repair/replacement applications for legacy equipment originally designed around a 240VAC primary.
