When the power meter is UL certified, refer to the UL 61010 standard. UL 61010 standard is about the safety requirements of electrical equipment for measurement, control and laboratory use. It stipulates the basic safety requirements of electrical equipment, including electrical safety, mechanical safety, environmental safety and so on.
UL 61010 standards apply to a variety of electrical equipment, including laboratory instruments, measuring equipment, automatic control systems, power supply units, etc., and the components associated with these equipment.
For electrical equipment such as power meters, UL 61010 standards may cover the following safety requirements:
l Electrical safety: The standard emphasizes electrical safety, including the selection and use of insulation, grounding, and insulating materials to ensure that the equipment will not cause electrical failure under normal operation.
Safety of machinery: The standard covers the mechanical safety of equipment, including construction, material selection, mechanical protection and stability of equipment to prevent mechanical accidents.
Environmental safety: The standard also considers the safety of the equipment under different environmental conditions, including factors such as temperature, humidity and corrosion.
