AC/DC 24 - 240 V

Product description

 

The Trafosafe TS1000 is applied at transformers with forced cooling. It monitors the temperature of the transformer with 3 sensor-circuits (PTC-thermistors), controls the forced cooling depending on the load of the transformer, reports exceeding of alarm-temperature and switches off the transformer (trip) when increasing of the temperature continues.

Up to 6 fans can be controlled and monitored directly with the TS1000. Contactors and motor protection switches are not necessary any more.

At Pt 100-monitored transformers the TS1000 can be used to control only the fans.

 

Temperature-Monitoring

  • 1 PTC-circuit for controlling the cooling (1T1/1T2) = input for starting fan when using as fan-control only
  • 2 x 1 PTC-circuit for alarm 1 (2T1/2T2) and alarm 2/trip (3T1/3T2), monitored for short-circuit and interruption
  • Alarm1 (K2) in closed-circuit current mode = monitoring of function
  • Alarm 2/trip (K3) in open-circuit current mode = no signal/tripping when switching on the device
  • Test-/Reset-button for testing the function

Fan-Control and Monitoring of fan

  • direct connection of up to 6 fans 0.07...4.0 A
  • automatic exceeding of the on-time of the fans at high load of the transformer
  • Monitoring of failure fan (over-/undercurrent)
  • Self-calibration of the monitored values of the currents to the fans
  • Switching-point for current-failure adjustable ± 5-40%
  • automatic test of fans 1-30 days, disconnectable
  • Relay for reporting fan-failure
  • Clear displays with LEDs

General

  • Universal Power Supply AC/DC 24-240 V
  • compact housing for cabinet-mount, 140 mm wide, mounting heigt 55 mm
  • Attachment on 35 mm standard rail or with 3 screws M4
