Mahjong machine transformer, falls under the category of ring transformers, generally with two sets of outputs, except for program machines. One set is 110V, the other is 12V. The power of one set is 160VA, and the other is 10VA.
A set of 110s is for the mahjong machine motor, the second set is for the computer board power supply, due to...Ring type transformerThere is an issue with voltage drop in actual usage. During the design and production of transformers, the voltage of a set is typically increased from 110V to around 120V-125V.

Ring-type transformers are primarily used as power transformers and isolation transformers. They are already available in a complete series internationally and are widely applied in computers, medical equipment, telecommunications, instruments, and lighting. Ring-type transformers offer excellent performance-to-cost ratios, with good output characteristics and anti-interference capabilities.
Circular Transformers: Standard, Economy, and Isolation Types
1) Our standard power transformer series ranges from 8 to 1500VA, featuring a low voltage regulation and a full-load operating temperature rise of only 40°C. It is designed for high-demand applications, allowing for short-term overload operation. The primary and secondary windings are insulated with B-grade (130°C) polyester film, requiring at least three layers of insulation tape, and can withstand an AC withstand voltage test of 4000V for 1 minute.
2) Economy power transformers series with capacity ranging from 50 to 1500VA, aiming to reduce costs while maintaining performance. Suitable for continuous operation without overloading, with a temperature rise of 60°C and an insulation material grade of A (105°C). Output voltage error is less than 3% under full load.
3) The isolation transformer product series ranges from 50 to 1000VA, and is further divided into two series: industrial and medical equipment. The focus of the isolation transformer is its insulation performance, with at least 4 layers of polyester film insulated with B-grade insulation between the primary and secondary windings, breakdown voltage exceeding 4000V, and all primary leads must be double-insulated wires. The transformer's maximum temperature rise is less than 45°C. For medical use, in addition to meeting the above requirements, the isolation transformer must also comply with the UL544 standard, which means the primary and secondary windings should have thermal protection, and the distance between the winding and the grounded copper shield should be greater than 13mm.
