HAC-MT One-way Low Power Wireless Metering Module
1. Ultra low power transmission, the effective output power is no more than 10mW (≤10dBm).
2. ISM frequency band with no requirement for applying frequency. The working frequency range is 433.5~434.6MHz.
3. The working voltage range is 2.8～6VDC. It is low power-consumption design, the static current is no more than 7µA, the average power-consumption is no more than 15µA. And the maximum pulse current is no more than 50mA.
Note: The capacity of ER18505 battery is more than 3600mAh. Suppose that: The actual using capacity of battery only reaches 50%, then the working life of battery is shown as follow: T = (3600 x 50% mAh) / (24h x 365 x 15µA) = 13.7 years.
4. It is a module with multi-features: collecting, metering, wireless communication, soft clock, ultra low power consumption, power supply management, break line fault detection, anti-magnetic attack, anti-disassembly and so on.
5. High speed transmitting mode: transmit once in random within 25~40s range, the visible communication distance is more than 500m (line of sight). Using with handheld terminal could solve the communication blind district completely. .
6. Low speed transmitting mode: transmit once in every 4 hours or transmit once in every 0.5m3 metering. Visible communication distance is more than 1500m (line of sight). It can be used with concentrator and repeater to finish fixed-point meter reading.
Dual-band & frequency-hoping mode can realize two frequencies transmitting, which could solve the same frequency interference problem of single frequency.
7. It supports single Reed Switch or double Reed Switches metering.
8. It has power supply management function, it could check and report voltage state of battery capacity.
9. Anti-Magnetic attack: when there is a magnetic attack, it will generate an alarm sign
10. Reserve Anti-Disassembly detection: When there is a disassembly attack, it will generate an alarm sign. (It needs to add additional ball switch for this function.)
11. Break line detection: When there is a break line fault, it will generate an alarm sign. It is suitable for external installation.
12. HAC-GWT and HAC-RPT are using TCXO crystal, which has high stability. Without no effect on sensitivity, it has automatic frequency tracking capabilities to offset the frequency drift caused by the aging of HAC-MT crystal.
