Description

Multipath temperature controller Technical Field The utility model relates to the field of temperature control, in particular to a multi-channel temperature controller. Background With the increasing requirements of the country on environmental remediation, the temperature controller is also more widely used in engineering applications. When the existing temperature controller is controlled to work under multi-path control, when high power and high current are used, particularly when overload work is caused due to overcurrent caused by peripheral factors, a large amount of heat can be generated, if the heat cannot be timely emitted and is not timely subjected to power-off protection, the heat can possibly occur to burn out devices, therefore, some heat dissipation devices and overcurrent protection are needed to be arranged in a circuit, the heat generated by the circuit can be timely emitted and subjected to power-off protection in time when overload is carried out, the protection effect is realized on components and the whole circuit, and the service life and safety of products are improved. In addition, although the electrical equipment applied in the market at present can be externally connected with a safety device, excessive wiring can be added when the electrical equipment is externally connected, for the high-current electrical equipment, the hidden trouble caused by poor line contact can be increased for each of a plurality of wiring connectors, and when the number of the electrical loads used on a large machine is huge, the line becomes complicated when the safety device is externally connected, and the production requirement on workers is high, so that the production cost is increased. Disclosure of utility model The utility model aims to provide a multi-path temperature controller which can realize independent control of multiple paths and improve the protection function of each path, and solves the problem that the normal operation of the whole controller is affected due to the problem of a certain path in the multi-path control.
