The MKPT-41-121000T low-voltage transformer is specially designed for electronic control boards and compact control panels. It converts 230VAC/50Hz mains into an isolated 12VAC/1A output, providing 12W of stable auxiliary power for relays, contactors, signal lamps and low-voltage logic circuits. The transformer uses an EI core structure with reliable insulation, low temperature rise and a compact 43×35×28mm size, making it easy to integrate into small control boxes and terminal equipment.

Key Features & Benefits
- Safe isolation for control circuits
Separate primary and secondary windings provide electrical isolation between 230VAC mains and 12VAC control circuits, helping protect the control board from surges and transient overvoltage. - Optimized 12VAC / 1A output
12W rated output (12VAC / 1A) is suitable for powering relays, indicator lamps, small motors or other auxiliary loads commonly used on control boards. - Compact footprint for small enclosures
With a size of only 43 × 35 × 28 mm and a weight of about 273 g, the transformer can fit into narrow spaces in HVAC controllers, small household appliances and compact industrial control panels. - Stable performance in 0–30 ℃ environments
Designed for an operating ambient temperature range of 0 ℃ to +30 ℃, suitable for typical indoor control cabinets, machine rooms and household equipment. - Global safety & EMC compliance
Designed to meet UL62368, EN62368, FCC Part 15, EN55032 and GB4943.1 requirements, helping your finished equipment pass certification faster and reduce project risk. - Built-in protection support
Supports temperature and current protection (to be coordinated with your overall power supply design), improving the reliability and service life of the transformer in long-term operation. - OEM / ODM for control board manufacturers
As part of Macable Group Company’s transformer series, input / output parameters, lead-terminal connection and mechanical details can be customized for your specific control board layout and application.
