Telecom cabinet power
One line into the network
A telecom cabinet is already on a network, so the power unit should join it rather than start a second one. The reporting line is 10/100M Ethernet with SNMP and Modbus, plus one RS485 port and an embedded web server. The input takes the same abuse as the site: 180V to 265V wide input with a surge path on the feed.
Reporting line- 10/100M + RS485 SNMP and Modbus, embedded web server
Wide input- 180V ~ 265V Surge and lightning path on the feed
Event log- 20,000 entries Built-in RTC holds the log through power loss
Energy register- 1 grade, 0.1 kWh Billing-grade total, +/-1%
The mechanism
Polled by the system that already exists
A telecom cabinet is visited on a maintenance round, not watched. The unit answers on the network the site already runs: the current, voltage, active power and accumulated energy for each reporting line go out over 10/100M Ethernet or the RS485 port, in the register layout an SNMP manager or a Modbus master expects. The embedded web server shows the same set in a browser when there is no collector on site, and SMTP sends the alert.

Telecom line sheet
Interface and electrical sheet
The first rows are the interface, because that is what a telecom cabinet is integrated on. The electrical rows sit under them, and the changeover row is the one that decides whether the cabinet rides through a failed feed.
| Parameter | Value | Note |
|---|---|---|
| Ethernet | 10/100M, 1 port | SNMP and Modbus over the same port |
| Serial | RS485, 1 port | Modbus RTU to the site controller |
| Local display | Industrial OLED | IP, current, voltage, power, energy, main switch state |
| Alerts | SMTP | Threshold and state changes leave the unit by mail |
| Event storage | 20,000 | Entries, held by the built-in RTC through power loss |
| Wide input, with protection | 180V ~ 265V | Surge and lightning path in front of the meter |
| Working voltage | 110V ~ 250V AC | The range the outlets are rated at |
| Input and output current | 10A–32A / 10A–16A | Input side / outlet side |
| Working frequency | 50Hz ~ 60Hz | Both nominal supplies |
| Input voltage range, meter | 90V ~ 350V | Scale 1V, +/-1% + 1 digit |
| Total current scale | 0.1A | +/-1% + 1 digit |
| Energy register | 1 grade, 0.1 kWh | Billing-grade total energy |
| Changeover option | ATS | Automatic transfer switch, for a cabinet on two feeds |
| Electrical testing | 100% | Every unit tested before packing |
- Ethernet port 10/100M
- Serial port RS485
- Site network SNMP / Modbus
- No collector on site web server
Both ports stay live at the same time. That matters where the cabinet is polled by an operator's SNMP manager and separately by a building controller on Modbus: neither has to be taken offline for the other, and the register set they read is identical.
Where the cabinet sits on two feeds, the changeover option puts an automatic transfer switch in the same envelope, so the meter, the log and the network port stay on one address through a transfer.- Ethernet10/100M x1

Registers the network reads
Each cell is one register group on the reporting line, with the resolution it reports at and where it can be seen. The site reads these over SNMP or Modbus; a technician reads them on the OLED.
-
Address and state
IP on OLED
Address, main switch state and the live reading on one screen, so a round confirms the unit is where the manager expects it.
-
Current per feed
0.1A
+/-1% + 1 digit per reporting line. This is the figure a rectifier load is checked against.
-
Voltage
1V
90V ~ 350V meter window, which covers the sag a long cabinet run produces.
-
Energy total
0.1 kWh
1 grade billing register. The smallest step the accumulated total reports.
-
Event log
20,000
Entries with the built-in RTC holding time through power loss, so a supply event survives the transfer that caused it.
-
Alerts
SMTP
Threshold and state changes leave the unit without a collector on site. Same conditions are readable as registers.

Name the port, the feed and the depth
Say which port the site polls, the current per feed, the outlet combination and how deep the metering goes. If the cabinet sits on two feeds, say so as well: the changeover option changes the envelope.
