Safety power supply for energy-saving electrical appliance

Abstract

The invention discloses a safety power supply for an energy-saving electrical appliance. Compared with the prior art, the safety power supply disclosed by the invention has the beneficial effects that a power-off time delay relay and a voltage-stabilizing rectifier are connected in series and then are in series connected with a plurality of galvanostats which are mutually connected in parallel, so that the voltage and the current can be stabilized, and the operation efficiency of the energy-saving electrical appliance is guaranteed; by using the power-off time delay relay, unnecessary loss caused by accident power outage can be prevented.

Description

technical field [0001] The invention relates to a power supply and a manufacturing method thereof, in particular to an energy-saving electric appliance safety power supply and a manufacturing method thereof. Background technique [0002] The mechanical products used in the factory are usually very powerful. Once the power is cut off suddenly or other accidents occur, it is very easy to cause damage to the mechanical products, or even cause a fire, with disastrous consequences. For example, the energy-saving LED power supply currently used is not stable enough, which may cause the current to be too large or too small, which cannot guarantee the LED to work under the normal operating current and affect the life of the LED. For example, the drive power supply whose publication number is 102695322A can guarantee the current and has a certain self-protection function, but its structure is complex and its applicability is low, so it is not suitable for other energy-saving electric...

Problems solved by technology

[0002] The mechanical products used in the factory are usually very powerful. Once the power is cut off suddenly or other accidents occur, it is very easy to cause damage to the mechanical products, or even cause a fire. The consequences are disastrous

For example, the energy-saving LED power supply currently used is not stable enough, which may cause the current to be too large or too small, which cannot guarantee the LED to work under the normal working current and affect the life of the LED.

For example, the drive power supply whose publication number is 102695322A can guarantee the current and has a certain self-protection function, but its structure is complex and its applicability is low, so it is not suitable for other energy-saving electrical appliances.
