ELKO EP TER-3 Single-Level Thermostats
ELKO EP TER-3 Single-Level Thermostats monitor temperature and regulation in the range of 0°C to +60°C (TER-3E and F) and -30°C to +70°C (TER-3A, B, C, D, G, and H). These devices are single, practical thermostats with a separate sensor for temperature monitoring (except for TER-3F). The TER-3 single thermostats are housed in a switchboard, and an external sensor senses the temperature of the required space, object, or liquid. These thermostats utilize a double-insulated sensor that is not galvanically isolated from the supply and support sensor cable lengths of up to 12m (39.4ft). The TER-3 single thermostats feature integrated sensor fault indication, with a flashing red LED signaling a sensor short circuit or disconnection. These devices can be used for temperature monitoring in switchboards, heating systems, liquids, radiators, motors, devices, and open spaces.
Features
- TER-3 (A, B, C, D, G, and H):
- -30°C to +70°C (-22°F to 158°F) in six ranges monitoring temperature range
- Adjustable hysteresis (sensitivity), switching by potentiometer in the range 0.5°C to 5°C (0.9°F to 9°F)
- Possibility to set the function "heating"/"cooling"
- Choice of external temperature sensors with double insulation in standard lengths of 3m, 6m, and 12m
- Possible to place the sensor directly on the terminal block for temperature monitoring in a switchboard or in its surroundings
- Red LED indicates the status of the output, and green LED indicates energization of the device
- TER-3 (E and F):
- 0°C to +60°C (32°F to 140°F) (E and F) monitoring temperature range
- 1°C/(1.8°F) fixed hysteresis
- TER-3E choice of external temperature sensors with double insulation in standard lengths 3m, 6m, and 12m
- TER-3F sensor is a part of the device and serves for monitoring temperature in a switchboard
