Metering specification

What the meter reads, and how precisely

Readings come from the metering platform, not from a nameplate figure. Every reporting line carries its own current transformer and its own meter circuit.

Reporting line

One circuit, one measurement

A reporting line is the smallest block the meter resolves: one feed, one group, or one outlet. The resolution you pick decides which scale the readings carry.

Scales in use: 0.1A current · 1V voltage · 0.1 kWh energy

Measurement chain

From the socket to the reporting line

Each outlet sits behind its own current transformer. The meter circuit reads that transformer, the OLED shows the result at the unit, and the network port republishes it.

Per outlet: current transformer
Meter circuit: ±1%, grade 1 energy
Local display: OLED, 6 readouts
Uplink: 10/100M Ethernet, RS485

Switching and network

Switch one outlet, or a whole group

Relays sit per outlet or per group, so a reboot can be scoped to a single device. The same firmware answers SNMP and Modbus, serves its own web page and sends SMTP alerts when a threshold trips.

Order route

From enquiry to a tested unit

Six stages, each with a document set behind it. Nothing is built until the electrical data on the drawing matches the feed you are installing into.

Enquiry and feed review

You send the four lines: outlet combination, current per feed, metering depth and whether remote switching is needed. We check them against the inlet, the breaker and the enclosure size.

Customer: four lines of electrical data

Configuration and drawing

The outlet set is fixed and an outline drawing follows, drawn per unit and per mounting orientation. The drawing carries current, frequency and protection ratings.

Customer: confirm the drawing revision

Enclosure and busbar

Cold-rolled steel is cut and formed for the chassis, then the copper busbar and the breaker bank are mounted. Conductors run to finalise at VDE 2.5mm² or 6mm².

Customer: mounting orientation and cable entry

Assembly and wiring

Outlets are wired into the busbar and identified against the drawing. Metering transformers are seated on the lines that need reporting.

Customer: label and numbering format

100% electrical testing

Every unit is powered before it is packed: continuity, polarity, insulation and function. Metering is compared against a reference, and the reading is recorded per line.

Customer: test record per line

Packing and documents

The unit is packed with the outlet row protected and the documents set inside. The specification sheet travels per line, with certificate titles and holder named.

Where the units go

Six places a rack PDU earns its cost

The metering depth changes with the room. A colocation circuit is billed per tenant, a test rack is switched per rig, and an edge cabinet is watched for ambient temperature.

Data hall: row-level metering, feeds to 32A
Server room: 10A to 16A outlet feeds
Colocation: billing-grade energy per circuit
Laboratory: per-outlet switching for test rigs
Edge cabinet: -30°C to 100°C ambient sensing
Telecom cabinet: 180 to 265V input, surge protected

Reference build

Electrical and mechanical data, line by line

Reading the table

Ratings stay paired

Current, frequency and protection are quoted together, because a rating on its own does not describe a feed. Outlet counts follow the drawing, not a catalogue number.

Tested: 100% electrical testing before packing

Read the feed before you switch it.
Design rule, IDCPDU metering platform

A switched outlet without a reading is a guess. The platform measures first, then lets the relay act, so a group reboot starts from a known current on each line.

Alarm path: SMTP on threshold
Events kept: 20,000 with RTC
Threshold basis: measured, not rated
