Quantity
The voltage conversion isolation transformer is a lead-acid type low-frequency power conversion component with a frequency range of 50Hz to 60Hz. This product features an integrated double-ear fixed embedded installation base, allowing for direct locking assembly with the chassis, control cabinet, and cable trough. The product is constructed using standard high magnetic permeability coercivity silicon steel sheets stacked in an EI-type core, featuring low magnetic loss and small no-load current. The winding is separated by a flame-retardant frame, and the coil is made of high-purity enameled copper wire, with the outer layer completely covered by multiple layers of rubber insulation tape. The entire unit undergoes high-temperature vacuum impregnation and drying treatment to ensure that the winding is compact and not loose, and has excellent insulation and withstand voltage performance.
The entire machine is equipped with color-coded leads. Different colored wires (such as red, blue and black) are used to distinguish between input and output terminals.
The standard model supports various voltage conversion specifications, such as 380V to 220V, 220V to 48V/36V/24V/12V. It has high-voltage and low-voltage electrical isolation functions, which can effectively isolate grid noise and leakage risks, and provide stable pure control voltage output. It is suitable for industrial environments where long-term uninterrupted power supply is required.

Core advantages of the 220v to 48v converter
1. The bridge frame and support are integrated, with strong installation adaptability.
It comes with a self-contained extended round-hole double-ear bridge base, eliminating the need for additional fixing components. Screws can directly lock onto the control cabinet, cable tray bridge frame, equipment base plate, wall-mounted box, and are compatible with various installation methods such as embedded, side-mounted, and horizontal placement. The assembly is simple and time-saving.
2. Electrical isolation is safe, and the anti-interference ability is strong.
The primary and secondary coil are completely insulated, blocking power surges and leakage conduction, protecting the rear circuit board and precision components; the metal shell + immersion paint shielding structure significantly reduces electromagnetic radiation, avoiding interference with sensors, PLC, and instrument signals.
3. Pure copper winding has low loss and is durable and stable.
The winding is made of oxygen-free pure copper enamel wire, with high conductivity efficiency. It has low temperature rise during long-term full-load operation and is not prone to overheating and aging; compared to aluminum wire transformers, it generates less heat and has a 2-3 times longer service life, suitable for 24-hour continuous working conditions.
4. Multi-layer insulation protection, with a high safety level.
The flame-retardant frame separates the coils, the double-layer Mala insulation film, and the overall immersion paint provide triple insulation protection. All are tested for high-voltage endurance at the factory, with a high breakdown voltage, preventing moisture and short circuits, and meeting the safety electricity usage standards for industrial control equipment.
5. Low vibration and low noise
The high-precision laminated silicon steel sheet core has uniform gaps, resulting in weak vibration during operation; the immersed paint fixed coil eliminates resonant noise from the coil, and can be used in silent environments such as computer rooms and instruments.
6. Dry type, maintenance-free, and has a wide environmental adaptability
It is oil-free, leak-free, and has no flammable media. It can be used in indoor normal temperature and mild humidity control cabinets, and no maintenance is required daily. It can withstand a wide temperature working range of -10℃ to 65℃.
7. Color-coded lead wires for identification, with zero wiring errors
Input and output use different colored wire materials for distinction. The body is printed with voltage parameter labels, allowing construction personnel to quickly distinguish between high and low voltage ends, effectively avoiding reverse voltage that could burn out control components.
8. Compact size, saving space
The compact EI core structure has a narrow thickness and occupies less space, perfectly adapting to small electrical control boxes, weak current boxes, and the internal narrow installation positions of instruments.
