Data centres need metering that never sleeps. NAHU high-accuracy instrument transformers give you IEC 61869-grade measurement on every feed — without ever leaving the circuit.
NAHU supplies IEC 61869 type-tested high-accuracy CTs, VTs, and indoor metering boxes engineered for continuous duty on data centre power paths — so PUE, capacity, and efficiency are always measured, never estimated.
High-accuracy CTs on UPS input, bypass, and static-switch feeds record every ampere, so PUE and power utilisation are measured — not estimated. NAHU indoor metering boxes keep the secondary wiring short, screened, and tamper-proof.
Class 0.2S measurement on critical IT loads gives operators the precision to detect drift and rebalance capacity before problems appear. NAHU high-accuracy CTs and VTs deliver the stable ratio and phase accuracy this demands.
Dual-secondary CTs and independent metering loops keep measurement continuous when a UPS or transfer switch changes path. NAHU multi-winding transformers drive two meters from one core set without derating accuracy.
Specify NAHU high-accuracy transformers for every metering point in your facility — from the MV incoming feed to the rack-level PDU. Tell us the accuracy class you need and we'll match it.
High-accuracy CTs up to class 0.2S with dual windings, tested to IEC 61869 for continuous precision metering.
Indoor VTs with stable 100 V secondaries for precise three-phase power measurement on MV feeds.
Indoor combined CT/VT metering boxes that fit neatly in MV switchgear rooms and electrical rooms.
