Dry-type transformers
Monitoring solutions for the operating parameters of dry-type transformers.
Thermal protection tailored to dry-type transformers
Choose the relay by the number and type of sensors and by how it integrates. All models below provide thermal protection; EP3, EP4 and EPU also send data over the internet.
Which relay to choose
Data from each product datasheet.
| EP3 IoT | EP4 IoT | EPU | RT49 | |
|---|---|---|---|---|
| Sensors | 3 PT100 | 4 PT100 | Up to 16 PT100/Cu10 | 2 PTC inputs, up to 4 in series |
| Communication | Wi-Fi, MQTT, Modbus, DNP3 | Wi-Fi, MQTT, Modbus, DNP3 | Wi-Fi, MQTT, Modbus RTU, DNP3, Modbus TCP/IP, DNP3 TCP/IP | Relay outputs |
| Power supply | 24 to 275 Vdc/Vac | 24 to 275 Vdc/Vac | 24 to 275 Vdc/Vac | 48 to 265 Vdc/Vac |
| Format | Compact, 37 mm deep | Compact, 37 mm deep | 98 × 98 × 94 mm | DIN rail, 22.5 mm wide |
To complete the installation
Sensors
Flexible RTD-PT100 sensors and a weather shelter with PT100 for ambient temperature.
Digitization
The RTU digitizes field signals and integrates the devices with the supervisory system.
Applications and maintenance
Dry-type transformers are used for their cost effectiveness, environmental appeal and ease of installation and maintenance. Applications include industrial plants, offshore platforms, commercial buildings, shopping centers, hospitals and airports.
