(3).DC-Error. Measured by watt hour meter and DC Immunity testing device, at 60/√2A ,the error of electronic meter is between ±3.0%(Double Core).See the test theory as following draft:
Electrical Performance Specification (1).Frequency insulation strength The primary winding to the secondary winding can undertake frequency AC 4000V and will not be penetrated for six SECs. long by 1mA creepage. (2).Insulation Resistance The primary winding to the secondary winding ≥1000MΩ (DC500V) (3).Leads requirements The secondary winding leads are two UL1430#26 silica gel soft wires. One is red and the other is black. And filled by black epoxy resin to CT. (4).High and low temperature is between -40~85℃,96hours . All parameters and electrical performance Not failed.
Package and Shipment Good packing and careful handling required in order to guarantee the products under good condition. Avoid drop, shake and other destructive action during transport.
Storage Air humidity is less than 95%(25℃) and any eroding gas or other harmful gas should be avoided. www.sh-smarttechnology.com |
