Current Sense / Low Frequency Tr a n s f o r m e r s CSE185L Description: Triad’s low frequency current sense transformers are designed to monitor current from 0.1 to 3 ampere at frequencies from 50 Hz to 400 Hz. Electrical Specifications at 25º C: Turns ratio: Primary to sense 1: 50 Suggested burden resistor: 60 Typical output: 110mV/Amp Primary DCR: 19.5 mΩ maximum Sense DCR: 23 Ω maximum Operating Temperature: -30°C to 95°C Storage Temperature: -50°C to 125°C Maximum input: 3Arms, 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 2500V, winding to winding and 1250V, winding to core. Agency Files: UL file E50476 – Electrical Insulation Systems, Class “B3”, 130C PC BOARD LAYOUT 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”.
