24V PoE Monitor
The 24V PoE monitor is a specialized circuit board we designed for monitoring off-grid communication sites. It provided regulation and control to 4x 24V outputs, as well as monitoring the current and voltage of the input and each output.
This board is designed to control power for 24V passive power injectors, a common scheme in long-range fixed-wireless systems. In addition to on/off control, the board also provides current and voltage measurements over its serial port for remote monitoring.
- 24V linear output regulators with heatsinking (up to 30V input)
- Hi-efficiency switching 5V power supply for MCU
- RS232 serial communication
- Relay control of outputs
- PTCs on each output for short-circuit protection
