This product is also available in open coil construction as CSE187L. Electrical Specifications at 25º C: Turns ratio: Primary to sense 1: 500 Suggested burden resistor: 60for 110mV/A Primary DCR: 270 micro ohms maximum Sense DCR: 21 ohms maximum Operating Temperature: -40°C to 105°C Storage Temperature: -50°C to 125°C Maximum input: 30Arms, 0-240VAC circuit Maximum output voltage: 4.0Vrms. Burden resistor value must be selected to not exceed this voltage. Response Curve: Construction: These transformers are provided with Recognized Component electrical insulation system (OBJY2), Class 130 (B), designated “B3”. Products are designed, built and 100% tested for a hi-pot of 4000V winding to winding. Agency Files: UL file E50476 – Electrical Insulation Systems, Class “B3”, 130C UL file E205349 – Component, Instrument Transformer (XODW2) RoHS Compliance: As of manufacturing date February 2005, all standard products meet the requirements of 2011/65/EU, known as the RoHS initiative. * Upon printing, this document is considered “uncontrolled”.
