- 3 INDICATORS-The protector base adopts 35mm rail type or device type, and has two screw hole structures inside, which can be directly installed separately or HT35 rail. Indicated by three indicators: normal, phase loss(voltage three-phase unbalance), reverse phase
- PHASE LOSS PROTECTION-Phase loss protection means that when the protected line is in the running state or non-operating state, any phase failure occurs, and the delay is 2S
- REVERSE PHASE PROTECTION-Reverse phase protection, a protection measure to prevent L1, L2, L3 three-phase AC phase sequence from being connected incorrectly, delay 2S action
- VOLTAGE IMBALANCE PROTECTION-Voltage imbalance protection, which refers to a protective measure that will affect the safe operation of the line due to three-phase voltage imbalance
- IDEAL FOR-Widely used in air compressors, electric motors, distribution boxes, water pumps, oil pumps, central air conditioning units, etc
- Temperature humidity and power status --- The GSM SMS environmental alarm is specially used to remotely monitor the temperature, humidity and power status of the site through the wireless GSM network.
- SMS reminder --- When the temperature, humidity, and power status exceed the high or low threshold, it will immediately send SMS reminders or call 6 preset mobile phones.
- 200 phone number --- Relay0 with dial‑up or SMS remote control. Up to 200 phone number can authorize the number. Since the call is not answered, the dial‑in control in GSM is free.
- Wide range of applications --- It only checks the caller's number, and if the number is authorized, it responds via relay activation. This can be used for parking latch control, GSM door openers, remote control machines, etc.
- Applicable place --- This temperature alarm can be used in greenhouses, vegetable greenhouses, breeding farms, factory buildings, etc.
