AH400 — LS AH400 Digital Energy Meter
The LS AH400 Digital Energy Meter is a precision Class 0.5 multi-function power quality instrument housed in a compact 96×96 mm DIN-format front panel enclosure, designed for revenue-grade energy monitoring and power quality analysis in medium-voltage and low-voltage distribution panels. The AH400 simultaneously measures voltage (L-N and L-L), current, active power, reactive power, apparent power, power factor, frequency, and accumulated energy (kWh/kVAr h), presenting all values on a large backlit LCD display with four-quadrant metering capability suitable for bidirectional energy flows including solar PV and co-generation installations. Its Class 0.5 accuracy meets IEC 62053-22 requirements, making it suitable for tenant sub-metering, energy cost allocation, and ARAMCO/SEC-compliant utility metering applications in Saudi Arabia.
The AH400 communicates via RS-485 Modbus RTU at baud rates up to 38.4 kbps, enabling direct integration with SCADA systems, building management systems, and energy management platforms. The meter supports programmable current transformer ratios (up to 9999:5 A) and voltage transformer ratios, allowing it to be used across a wide range of current levels without hardware change. It operates on a self-powered 85–264 V AC auxiliary supply and withstands 6 kV impulse testing in accordance with IEC 61000-4-5, ensuring reliable operation in environments with transient surge events common in Saudi industrial facilities. The front-panel IP54 rating protects against dust and water ingress in industrial switchboard applications, while the rear terminals accept up to 4 mm² conductors for straightforward wiring.
Saudi Arabia's energy efficiency regulations under the Saudi Energy Efficiency Center (SEEC) and Vision 2030's industrial sector energy targets are driving widespread deployment of sub-metering infrastructure in factories, commercial buildings, and utility facilities. The AH400 is widely used by facility managers at MODON-managed industrial estates and by SEC-approved metering contractors for tenant energy billing in multi-occupancy commercial developments in Riyadh, Jeddah, and Dammam. Its DIN-format 96×96 mm housing fits standard existing switchboard cutouts, enabling cost-effective retrofits without panel modification. The meter's four-quadrant metering and reactive power measurement also support power factor correction system monitoring and VAr management in plants with large motor loads.

Key Features & Benefits
- Class 0.5 accuracy per IEC 62053-22 enables revenue-grade energy billing and ARAMCO/SEC-compliant sub-metering without separate revenue meters in many applications.
- Four-quadrant energy metering (import/export kWh and kVArh) supports bidirectional energy flow measurement for solar PV, co-generation, and power factor correction monitoring.
- RS-485 Modbus RTU communication with programmable baud rate up to 38.4 kbps allows direct integration with SCADA, BMS, and energy management software without protocol converters.
- Programmable CT and VT ratios up to 9999:5 A cover installations from small sub-distribution boards to medium-voltage metering panels without hardware change.
- Standard 96×96 mm DIN housing fits existing switchboard cutouts for cost-effective retrofits in commercial and industrial panels without modification.
- IP54 front panel rating protects the display and controls from dust and water ingress in industrial switchboard environments across Saudi Arabia's coastal and desert sites.
Industrial Applications in Saudi Arabia
- Tenant sub-metering in multi-occupancy commercial and industrial buildings at MODON industrial estates for accurate energy cost allocation and billing among tenants.
- Energy monitoring in manufacturing facilities targeting SEEC energy efficiency compliance and Vision 2030 industrial sector energy reduction targets.
- Power factor correction capacitor bank monitoring where reactive power measurement enables precise compensation control and penalty charge avoidance on SEC utility tariffs.
- SEC-compliant utility metering installations in small-to-medium LV distribution panels where Class 0.5 accuracy meets network operator requirements.
- Solar PV and co-generation facility metering where four-quadrant capability correctly accounts for both import and export energy flows for grid settlement.
