The Triad Magnetics Transformer, part number 76K3910, is designed for current sensing applications, capable of monitoring currents from 0.1 to 30 amperes at frequencies ranging from 50 Hz to 400 Hz. It features a turns ratio of 1:500 and a suggested burden resistor value of 60,Ѷ, providing a typical output of 110mV/Amp. The primary DC resistance is specified at a maximum of 250 micro ohms, while the secondary DC resistance is limited to 21 ohms. This transformer operates within a temperature range of -30¬8C to 95¬8C and can handle a maximum input of 30Arms in a 0-240VAC circuit, with a maximum output voltage of 4.0Vrms. The construction includes a Recognized Component electrical insulation system, ensuring compliance with safety standards, including a hi-pot test of 2500V winding to winding and 1250V winding to core. Additionally, the product is RoHS compliant as of February 2005.
Designed to monitor current in low frequency applications.
