Home Industries Colocation
Colocation
Metering a tenant can be billed from
In a shared cage the feed is a commercial instrument, not a status light. The energy register is a 1 grade billing-grade meter at Scale 0.1 kWh, and current, voltage and power report at +/-1% on the same line, so a tenant statement and a capacity plan read from one source.

- Metering depth

Where the tenant boundary sits
A multi-tenant cage draws the commercial boundary at the outlet group, not at the row. Per-outlet metering puts the boundary where the tenant lease puts it, and the energy register keeps counting at 0.1 kWh steps so a monthly statement reconciles against a sub-meter rather than against an estimate.
- Energy step
- 0.1 kWh
- Register grade
- 1 grade, billing
- Current step
- 0.1A
- Power accuracy
- +/-1%
- Log depth
- 20,000 entries
- Log retention
- Built-in RTC, power-loss held
- Figure the tenant is charged on energy per outlet
- Figure that catches a runaway current per group
- Figure that survives a transfer event log
Parameters a lease is written against
Colocation line sheet
These are the figures that end up in a colocation schedule: what the register reports, at what step, and how many tenant circuits one unit can carry.
| Parameter | Value | Note |
|---|---|---|
| Energy register grade | 1 grade | Billing-grade total energy |
| Energy scale | 0.1 kWh | Smallest step the total reports |
| Metering accuracy | +/-1% | Current, voltage and power |
| Metering depth | Per outlet | Boundary follows the lease |
| Current scale | 0.1A | +/-1% + 1 digit, per reporting line |
| Voltage scale, meter | 1V | Meter window 90V ~ 350V |
| Rated current | 16A / 32A | Three-phase tenant feeds |
| Working voltage | 110V ~ 250V AC | Per phase |
| Working frequency | 50Hz ~ 60Hz | Both nominal supplies |
| Data path | 10/100M + RS485 | SNMP and Modbus, web server, SMTP alerts |
| Event storage | 20,000 | RTC held through power loss |
Per-outlet metering is what separates a tenant statement from a share of the room. The register has to be a billing grade, the step has to be small enough to reconcile, and the reading has to leave the unit without a technician copying it by hand.
One unit can report every tenant circuit in the cabinet on its own line, so a rack that changes hands mid-term keeps its history instead of starting a new log.

Figures a tenant statement is built from
Each cell is one register group on the tenant line. The step matters as much as the accuracy: a 0.1 kWh register reconciles against a rented sub-meter, an estimate does not.
-
Energy
0.1 kWh
1 grade billing register. The smallest step the tenant total reports.
-
Depth
Per outlet
One reporting line per tenant circuit, so the boundary follows the lease.
-
Current
0.1A
+/-1% + 1 digit on each line. Catches a circuit drifting toward its breaker.
-
Voltage
1V
Meter window 90V ~ 350V, so a sag is recorded instead of lost.
-
Event log
20,000
Entries held through power loss by the built-in RTC. This is the audit trail.
-
Data path
SNMP / Modbus
10/100M Ethernet plus one RS485 port, embedded web server, SMTP alerts.
Send the rack
Tenant circuits, current, metering depth
Tell us how many tenant circuits one unit has to report on, the current per feed and whether the energy register has to be billing grade. The reply is a configured quotation with a per-line specification sheet, in English.
Inquiries are answered within 12 business hours. The register map travels with the specification sheet, so billing can be wired up before the unit lands.
