Description:

Triad’s low frequency current sense transformers are designed to monitor

current from 0.1 to 30 amperes at frequencies from 50 Hz to 400 Hz.

This product is also available in potted coil construction as CSE187L-P.

Electrical Specifications at 25º C:

Turns ratio: Primary to sense 1: 500

Suggested burden resistor: 60Ω

Typical output: 110mV/Amp

Primary DCR: 250 micro ohms maximum

Sense DCR: 21 ohms maximum

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

UL file E205349 – Component, Instrument Transformer (XODW2)

RoHS Compliance: As of manufacturing date February 2005, all standard

products meet the requirements of 2002/95/EC, known as the RoHS initiative.
