Rated secondary voltage: 100V.
Accuracy levels include 0.2 and 0.5, with rated outputs ranging from 15VA to 30VA and limit outputs ranging from 200VA to 400VA. The rated insulation levels are 7.2/32/60kV and 12/42/75kV
.
Normal usage conditions:
Installation location: Indoor.
Environmental temperature: maximum+40 ºC; Minimum -5 ºC.
Altitude: not exceeding 1000m.
Atmospheric conditions: There is no severe pollution in the atmosphere
.
Structure and characteristics:
This type of transformer is a semi cast iron core with an outer core. The primary winding is led out at both ends and equipped with a terminal block, which can be used to connect high-voltage wires
.
The winding of the transformer is an epoxy resin fully vacuum cast fully insulated structure, and the iron core is made of high-quality silicon steel sheets stacked together. The product has a small volume and light weight, and installation only occupies limited space
.
Appearance and installation dimensions:
Specific exterior drawings and installation dimensions can refer to the information provided by the manufacturer or product manual
General
