Enercept® Networked Power Meters (Modbus® RTU)

�� �� APPLICATIONS

 Energy managing & performance contracting

 Sub metering for commercial tenants

 Activity-based costing in commercial and industrial facilities

 Real-time power monitoring

The world’s most cost-effective meter

 Monitor energy parameters (kW, kWh, kVAR, PF, Amps, Volts) at up to 63 locations

on a single RS-485 network...greatly reduces wiring time and cost

 Fast split-core installation eliminates the need to remove conductors...saves time and labor

 Precision metering electronics and current transformers in a single package–reduces

the number of installed components– huge labor savings

 Smart electronics eliminate CT orientation concerns–fast trouble-free installation

High accuracy

 ±1% total system accuracy, (10% to 100% of CT rating)

The Enercept H8035/8036 are innovative three-phase networked (Modbus RTU) power meters

that combine power metering electronics and high accuracy industrial grade CTs in a single package. The need for external electrical enclosures is eliminated, greatly reducing installation time and cost.

There are two application-specific platforms to choose from. The Basic Enercept Energy Meters (H8035) are ideal for sub metering applications where only kW and kWh are required. The Enercept Enhanced Data Stream meters (H8036) output 26 energy variables including

kW, kWh, volts, amps, and power factor, making them ideal for power monitoring and diagnostics.

Color-coordination between voltage leads and CTs makes phase matching easy. Additionally, these meters automatically detect and compensate for phase reversal, eliminating the concern of CT load orientation. Up to 63 power meters can be daisy chained on a single RS-485 network.

Protocol Modbus RTU** (*)

** Detailed protocol specifications are available at: http:// www.veris.com/modbus/

* Other protocols available. Please consult factory.

†† Contact factory to interface for voltages above 480VAC or current above 2400 Amps

††† Do not apply 600V Class current transformers to circuits having a phase-to-phase voltage greater than 600V, unless adequate additional insulation is applied between the primary conductor and the current transformers. Veris assumes no responsibility for damage of equipment or personal injury caused by products operated on circuits above their published ratings.
