The GTB10 and LPB2 series products are contactless magnetic-resistance control equipment developed based on the GTB6 and LPB1 series products, and have all the functions of the GTB10 series products. It also has the following characteristics:

1. The switch guide system adopts the internationally advanced IGBT technology, with short switching time, small power consumption, convenient control, and has short circuit protection.   

2. The control method adopts all-electronic digital control technology, single-board computer chip instructions, which can accurately control each touch and simulate, improve the accuracy of various technical indicators, and has a multi-channel fault detection system. It has a strong overall protection function, reduces the failure rate of each piece and has high reliability.   

3. Use small signals to control high-power components, use contactless electronic switches to switch the suction and discharge, and use zero current working mode for opening and closing of the contactor, so there is no electric spark, no dry sound, no mechanical vibration, and no electromagnetic interference.   

4. Multi-point voltage detection is adopted. There are super control systems for overvoltage, undervoltage, and power outage. The response speed is fast, the return position is accurate, and the battery capacity alarm is provided to avoid power outage and magnetic protection failure caused by the failure of the battery for too long.   5. Multi-point current detection is used to generate alarm signals for short circuits, overcurrents, and loop blockages, reminding users to shut down and check. All alarms have positioning instructions for easy maintenance.   6. Adopt the inverter storage technology and energy feed the power grid.
