AmpRack · Intelligent Rack PDU

Outlet-Level Intelligence.
Factory Direct.

Metered, switched and per-outlet monitored rack PDUs — engineered on our own PCBA line, calibrated to ±1% and 100% tested before shipment.

By the numbers

Specs you can hold us to

±1%

billing-grade energy metering, calibrated per unit against a reference source

100k

mechanical cycles rated for every per-outlet switching relay

36kW

maximum output from a single 63A three-phase WYE vertical PDU

100%

of units pass 1500V AC hipot, functional and 48-72h full-load burn-in tests

Live telemetry, open protocols

Every outlet talks. Your DCIM listens.

SNMP v1/v2c/v3 REST API MQTT cloud daisy-chain ×8 / IP sensors RJ12 ×4 Modbus TCP

One AmpRack PDU streams second-level telemetry to Sunbird, Device42, Nlyte or your own stack over SNMP v3, REST or MQTT — no gateways, no licensed add-ons. Chain up to eight units on a single IP address and add temperature, humidity, door and leak sensors wherever the rack needs eyes. Firmware updates ride the same channel, and every value is also pollable over Modbus TCP for the BMS side of the building.

How we work

From inquiry to loading bay

1

Inquiry

Tell us input, outlet count, metering grade and quantity. An engineer — not a sales script — replies within 48 hours.

2

Spec review

We confirm phase, breaker sizing, outlet mix and protocol set against your rack load plan, then quote FOB.

3

Sample

Standard units ship from stock; custom builds run through our pilot line in 3-7 days for your bench test.

4

Order

T/T 30% deposit to start. You get a named QA contact and serial-range visibility for the batch.

5

Production & test

SMT to final assembly in-house, then 100% calibration, functional, hipot and burn-in before packing.

6

Shipment

FOB, CIF or DDP. Cartons of 4-8 units, drop-test approved, with packing list and test records.

Our own line, our own boards

We build the PCBA.
Then we build the PDU around it.

SMT, calibration, assembly, hipot and burn-in under one roof — that is why the ±1% on the datasheet matches the unit in your rack.

Tour the factory

Why AmpRack

Built by the factory, not the trading desk

Calibration is a station, not a claim

Every PDU passes a reference-source bench before the housing closes: ±1% is verified per unit, and the calibration record ships with the serial range of your batch. There is no "typical accuracy" footnote to apologize for later.

Relays we would use ourselves

Per-outlet switching uses 16A relays rated for 100,000 mechanical cycles behind hydraulic-magnetic breakers that do not derate in a warm rack. The switching bank is our own PCBA design — the same line that powers the metering board.

Protocols first, lock-in never

SNMP v3 with our MIB, REST with documented endpoints, MQTT to your broker — no proprietary manager, no per-point license. If your DCIM can read a counter, it can read an AmpRack.
