So R1 should be calculated so that the rated voltage to be measured corresponds to a primary current of 10mA.For example: Measuring rated voltage VPN=250V:R1=25K/2.5W,IP=10mA Accuracy=±0.5% of VPN; b) R1=50K/1.25W,IP=05mA Accuracy=±1.0% of VPN; Operating range(recommended):taking into the resistance of the primary windings(which must remain low compared to R1.in order to keep thermal deviation as low as possible) and the isolation,the sensor is suitable for measuring nominal voltage from 10 to 500V.Company Profile Packaging & ShippingPackage All our sensors will be well packed with bubble & carton. (Bubble packing→4 small carton→1 big carton)You can choose your own label(Screen Print or Laser Engraving).Can be netural packing or OEM.ShippingProducts are shipped via UPS / DHL/ FedEx / TNT, etc. (door to door), or air & sea shipment for larger qty.L/T: 3-7 days upon receiving payment if the qty is lower than 1000PCS and it is not customized products.Shipping via DHL. UPS. FedEx and TNT express usually takes 3~7days dependent on the destination country.
