Home Industries Data hall
Data hall
Meter the feed, hold the row
A cabinet in a data hall is booked against one feed, so the number that matters is that feed's current and energy. Metering accuracy is +/-1% on current, voltage and power, and the energy register is a 1 grade billing-grade meter at Scale 0.1 kWh.
- Metering accuracy

What gets measured
Every figure the row is booked against
A row meter shows what the row drew. A cabinet feed meter shows what that cabinet is billed for, and that is the figure a capacity plan and a customer invoice both need. The unit reports current, voltage, active power and accumulated energy on each reporting line, plus ambient temperature at the top of the cabinet.
- Current scale
- 0.1A
- Current accuracy
- +/-1% + 1 digit
- Voltage scale
- 1V
- Energy scale
- 0.1 kWh
- Energy grade
- 1 grade, billing
- Ambient resolution
- 1°C
- Reading that sizes the feed current per feed
- Reading that proves headroom phase balance
- Reading that supports a chargeback energy per line
Parameters the row is checked against
Data hall line sheet
These are the figures a data hall line is signed off on. Each row is a setting on the unit, not a marketing range: the meter window, the current, the conductor and the outlet rank.
| Parameter | Value | Note |
|---|---|---|
| Metering accuracy | +/-1% | Current, voltage and power |
| Input voltage range, meter | 90V ~ 350V | Scale 1V |
| Current scale | 0.1A | +/-1% + 1 digit |
| Energy register | 1 grade, 0.1 kWh | Billing-grade total energy |
| Working frequency | 50Hz ~ 60Hz | Both nominal supplies |
| Rated current per outlet | 10A / 16A / 32A | IEC C13 10A, IEC C19 16A |
| Working voltage | 110V ~ 250V AC | Single-phase feeds |
| Wide-input protection | 180 ~ 265V | Surge and lightning path |
| Communication | 10/100M + RS485 | SNMP and Modbus, embedded web server |
| Ambient sensing | -30°C ~ 100°C | Humidity 1% ~ 99% |
| Event storage | 20,000 | Held by the built-in RTC |
The meter window is wider than the feed. That is deliberate: a 90V floor and a 350V ceiling cover the nominal supplies a data hall row is built on, and the register keeps counting through the sag that a transfer would otherwise hide.
Ambient sensing is fitted to the reporting unit, not bought as a separate probe. Temperature and humidity sit on the same register map as current and energy, so one poll answers both.

Readings that are actually polled
Each cell below is one register group on the reporting line. The scale is the resolution the meter reports at, taken from the specification sheet rather than rounded for presentation.
-
Energy total
0.1 kWh
Billing-grade register, 1 grade. Scale is the smallest step the total reports.
-
Current per feed
0.1A
+/-1% + 1 digit, per reporting line. This is the figure a capacity plan uses.
-
Voltage
1V
90V ~ 350V meter window, so a sag stays on the register instead of dropping out.
-
Active power
+/-1%
Power is derived from the same sampling as current and voltage, not from a second meter.
-
Ambient at the top
-30°C ~ 100°C
1°C resolution, humidity 1% ~ 99%. One sensor answers both readings.
-
Event log
20,000
Entries held by the built-in RTC through power loss, so an audit trail survives a transfer.
Send the rack
Feed current, outlet mix, metering depth
Three lines about the cabinet are enough to size the feed: current per feed, the outlet combination and whether billing-grade energy is needed per line. The reply is a configured quotation with a per-line specification sheet, in English.
