Brand Profile Right box

Founded in 1993, APT is a leading brand of low-voltage control electrical appliances in China, the brand name is derived from the first letters of three English words, Advanced (A), Perfect (P), Top (T), which means: advanced, perfect, excellent. In August 2008, Siemens acquired the APT brand and assets, and APT became a subsidiary of Siemens. After APT was integrated into Siemens, it continued to focus on the development and production of buttons, signal lights, transfer switches, relays, control boxes, current transformers, limit switches and other important low-voltage products.

In January 2009, the APT logistics distribution system was standardized; In March, for the first time, the sales staff target agreement was introduced for performance management, and the employee salary appraisal system was reformed. In June, the SAP system was officially launched, and a customer credit control system was established.

In January 2010, APT Shanghai Branch's Jiading Factory was merged into Tiantai Factory. In March, APT officially introduced EBP for indirect material procurement; In April, APT's first new product, PB1M metal button, was officially launched; In June, the inventory management barcode system of Tiantai factory was officially put into use.

On May 8, 2019, APT's new x.R series relays were launched, and on September 20, the FY19 Siemens APT National Dealer Annual Conference was held in Jinan.

At the same time, Siemens will leverage its international experience to strengthen APT's quality management and business development, and rely on advanced technology and R&D resources to make the APT brand better serve Chinese customers.

Siemens APT current transformer – current transformer operating error When the current transformer is finalized and its internal parameters are determined, the magnitude of the error will be affected by the secondary current (or primary current), secondary load, power factor, and frequency. These factors are called external factors, and the error of the current transformer in operation is mainly affected by these four factors. ... MORE>>
	Siemens APT transformer – common faults and analysis of voltage transformers (1) The insulation between the iron chips is damaged Problem: The temperature rises during operation. Possible causes of the problem: (1) Poor insulation between iron chips (2) The use of harsh environmental conditions or long-term operation at high temperature to promote the aging of insulation between iron chips. （ ...
	Siemens APT relay - the cause and solution of the fault of the high-voltage relay 1. Some common faults of high-voltage relay coils 1. The common fault cause of the coil is often disconnected: whether the ultrasonic wave is used to clean the high-voltage relay, or whether the overvoltage is added to the coil will also promote the probability of the coil being disconnected. 2 ...
	Introduction to the characteristics of Siemens APT relays - solid state relays Solid state relay is a non-contact electronic switch with isolation function, no mechanical contact parts in the switching process, so in addition to having the same function as electromagnetic relay, solid state relay also has logic circuit compatibility, vibration resistance and mechanical impact resistance, unlimited installation position, and good anti-...
