Relé térmico TS1000

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
