POWER SUPPLY requirement with 12V supply
CONTROLMATE:
- Start-up, approx. 200mA (with short peaks during network registration).
- MODEM ON: No LCD or LED, no relays active 90mA when idle.
- MODEM OFF: No LCD or LED, no relays active 50mA when idle.
- LCD, add 15mA, or each relay on 20mA, LED panel adds approx. 80mA
While actually sending SMS messages, add approx. 150mA to any situation.
•
If the (30 sec) average supply drops below a reliable operating voltage, a warning is sent to
ADMIN users. If the supply drops below a critical level, the controller enters low-power state,
and can only be restarted with a power-cycle.
•
Supply voltage is displayed for confidence purposes only.
•
Input trigger current ~2mA (<2K7 ohms across closed-contact).
•
High-side input opto-couplers are biased to +5V via 330-ohm pull-up.
•
If the modem has been turned off, and no attempt at outgoing messages has been
made for 24 hours, the controller will enter hardware deep-sleep to conserve
remaining battery condition. Only a power-cycle can restart normal operation.
