Digital Temperature Controller Dry Transformer Protection TR-100

Digital Temperature Controller Dry Transformer Protection TR-100

Product Details:

Type Digital
Power 24 VDC, 100 to 240 VAC
Temperature Range -40 to +240 deg C
Model Number TR-100
Application Dry Transformer and HV Motor Protection

TR-100 is used to measure and control device temperature via four RTD sensors connected in a two or three-wire circuit, with subsequent indication of the temperature on the display and alarm signaling in case of any parameters being outside the set range.

It can be used to protect:

  • Engines and generators
  • Three phase dry transformers with additional core or ambient temperature control

TR-100 can use any voltage between 24 and 225V AC, regardless of the polarity.

The following thermal sensors can be used by TR-100:

  • PT100 – platinum sensor with nominal resistance of 100 Ohm at 0
  • PT1000 – platinum sensor with nominal resistance of 1000 Ohm at 0
  • KTY83 – silicon sensor with nominal resistance of 1000 Ohm at 25
  • KTY84 – silicon sensor with nominal resistance of 1000 Ohm at 100
  • PTC (1, 3, 6 serial connection), cold resistance of 20-250 Ohm

Temperature Range: -40 to +240 deg C

Display Size: LED 3 x 7 Segment

Controller Type: On/Off Control

Input Sensor: RTD
