Johnson Controls H8026-2400-4 2400 Power Meter

The Johnson Controls H8026-2400-4 2400 Power Meter is a high-capacity networked N2 bus power meter designed for precise energy sub-metering in commercial and industrial HVACR environments. Engineered for integration with Metasys building automation systems, this unit monitors 3-phase electrical loads with high-demand accuracy of ±1% from 2% to 100% of the rated current. Operating within a 208-480 Vac voltage range and rated for 2400 Amp applications, it provides essential data points including real-time power consumption, voltage, and amperage across the N2 communication protocol. The robust hardware supports an operational temperature range of 0-60°C and 0-95% non-condensing humidity, ensuring reliability in mechanical rooms. This industrial power monitoring device is optimized for HVAC energy management, allowing contractors to implement peak demand shedding and granular utility allocation without requiring extensive external power supplies for the meter itself.

• Seamless N2 Integration: Native compatibility with Johnson Controls Metasys networks using the N2 protocol for streamlined data mapping.
• High-Amperage Capacity: Rated for 2400 Amp loads, making it suitable for large-scale chillers and central plant distribution panels.
• Superior Accuracy: Maintains ANSI C12.1 revenue-grade accuracy levels at ±1%, critical for precise sub-metering applications.
• Industrial Build: Designed to withstand fluctuations in commercial electrical monitoring environments with a wide operating temperature tolerance.

How do I address the H8026-2400-4 on an N2 bus?
The device uses standard N2 addressing; ensure the DIP switches are set to a unique address between 1 and 255 before performing a device discovery in your supervisory controller.

What CTs are compatible with this Johnson Controls power meter?
This specific model is calibrated for 2400A applications; ensure the current transformers used match the millivolt output requirements as specified by the H8026 series technical data sheet.

Does this unit require a separate control power source?
The H8026 series is typically line-powered from the phases it monitors, reducing the need for additional HVAC power supply wiring during installation.
