LED power supply

A lamp controller, comprising a circuit board, a main housing, a plug-in socket and an output plug-in component, wherein the main housing consists of an upper housing and a lower housing, the upper housing and/or the lower housing are provided with cavities, after the upper housing and the lower housing are combined, an accommodating cavity for assembling the circuit board is formed between the upper housing and the lower housing, the axial direction of the plug-in socket is not parallel to the longitudinal direction of the main housing, and the output plug-in component is fixed with the plug-in socket, wherein the controller further comprises an output connecting terminal, the output connecting terminal is fixed on the circuit board, the circuit board is provided with a yielding opening, a part of the output plug-in component is located in the cavity of the upper housing or the lower housing.

Decorative lamp controller

Disclosed is a carbon dioxide heat pump evaporator, comprising side evaporators having defrosting water flow channels formed thereon, an evaporator tray which is arranged at the bottoms of the side evaporators and is used for supporting the side evaporators, and a defrosting drainage system, wherein the defrosting drainage system comprises a plurality of defrosting electric heating tubes inserted into the side evaporators, water receiving gutters which are connected to the defrosting water flow channels, gutter electric heating mechanisms for heating the water receiving gutters, and drainage pipes which are connected to the water receiving gutters and are provided with conduit electric heating tracing bands; and the evaporator tray, the water receiving gutters and the drainage pipes are sequentially arranged from top to bottom. The carbon dioxide heat pump evaporator is suitable for low-temperature areas, especially for areas of extreme cold, and has the characteristics of a short defrosting time, smooth drainage, etc.

Carbon dioxide heat pump evaporator

A motor controller configured to be coupled to a motor that is coupled to a fan is described. The motor controller includes a processor coupled to a memory, and is configured to operate the motor in a first operating mode in which the motor rotates the fan in a first direction at a first speed. The motor controller is further configured to operate the motor in a restriction detection mode in which the motor rotates the fan in a second direction that is opposite the first direction, determine a torque associated with the motor while the motor is rotating the fan in the second direction, determine that the torque is not within a predefined threshold range in the memory, and determine that a restriction exists in a fluid flow path associated with the motor in response to determining that the torque is not within the predefined threshold range.
