AURORE RLT 3 Phase Digital kWh Meter DTS-238 415V
The AURORE RLT DTS-238 is a high-precision Class 1 three-phase electronic digital kWh meter designed for 3x240/415V 50Hz low-voltage electrical systems. Supporting direct current loads from 10A up to 100A, this unit provides reliable, tamper-resistant active energy sub-metering for commercial, industrial, and multi-tenant residential facilities in Malaysia. Manufactured in compliance with international standards IEC62053-21 and IEC62052-11, the DTS-238 delivers stable performance, low power loss, and accurate energy consumption tracking without needing external current transformers for up to 100A applications.
Full Description:
The AURORE RLT DTS-238 Three Phase Electronic kWh Meter is engineered to meet the demanding power monitoring requirements of modern commercial complexes, factories, and commercial switchboards operating on Malaysia’s standard 415V 3-phase supply grid. Accurate sub-metering is essential for facility managers, electrical contractors, and building owners who need precise power measurement to manage energy costs, allocate utility expenses accurately among tenants, or track machinery power consumption.Constructed using advanced Surface Mount Technology (SMT) and high-grade micro-electronic components, the DTS-238 provides uninterrupted active energy tracking with high resistance to electromagnetic interference. Its direct-connect 10/100A current rating allows direct wiring into standard sub-panels, eliminating the complexity and extra cost associated with installing separate Current Transformers (CTs) for loads up to 100 Amps.
Key Features and Benefits
- High Precision Class 1 Accuracy: Delivers precise active energy metering with a margin of error within ±1%, ensuring reliable data for internal energy audits and tenant electricity bill calculations.
- Wide 10(100)A Direct Load Range: Capable of measuring low starting currents while continuously handling heavy industrial loads up to 100 Amps without saturation or overheating.
- International IEC Certification: Full compliance with IEC62053-21 and IEC62052-11 standards guarantees robust insulation, overvoltage protection, and long-term durability under tropical climate conditions in Malaysia.
- Tamper-Evident & Anti-Electromagnetic Protection: Built-in shielding prevents external magnetic fields from distorting electricity consumption readings, guarding against energy theft and measurement drift.
- Low Self-Power Consumption: Designed with internal circuitry that consumes minimal baseline power, lowering ambient heat generation inside tight electrical distribution boxes.
- Clear Visual Display: Clear multi-digit LCD panel allows maintenance personnel to record readings swiftly without manual mathematical conversions.
Applications in the Malaysian Market
- Industrial Manufacturing & Factories: Ideal for monitoring power usage of heavy machinery, production lines, motor control centers (MCC), and industrial HVAC units to calculate operational costs per unit produced.
- Commercial Real Estate & Malls: Perfect sub-metering solution for shop lots, retail kiosks, food courts, and office suites where individual tenant billing must be separated from main Tenaga Nasional Berhad (TNB) utility meters.
- Data Centers & Server Rooms: Enables IT managers to track power usage effectiveness (PUE) by monitoring 3-phase rack distribution units.
- EV Charging Stations & Solar Systems: Tracks power drawn by 3-phase AC EV chargers or energy generated in commercial solar sub-systems.
Installation & Compliance Guidelines
Installation must be performed by a Suruhanjaya Tenaga (ST) certified electrician or registered electrical contractor in accordance with local wiring regulations (MS IEC 60364). Ensure main power feeds are isolated prior to landing 3-phase lines (L1, L2, L3) and Neutral onto the marked terminal blocks. Always verify line wire gauge is properly rated to safely carry up to 100A continuous current.

Q1: What is the primary use of the AURORE RLT DTS-238 3-phase digital kWh meter?
A: The AURORE RLT DTS-238 measures active electrical energy consumption in 3-phase 415V electrical systems, commonly used for sub-metering tenants, commercial premises, and industrial equipment in Malaysia.
Q2: Is the AURORE RLT DTS-238 compatible with Malaysia’s standard 3-phase voltage?
A: Yes, it is fully rated for 3×240/415V at 50Hz, matching the low-voltage 3-phase distribution standards used across Malaysia.
Q3: What does Class 1 accuracy mean for a digital kWh meter?
A: Class 1 accuracy means the energy meter has a maximum allowable error margin of ±1.0% across its operating range, fulfilling standards required for accurate commercial sub-billing.
Q4: What are the IEC62053-21 and IEC62052-11 standards?
A: IEC62052-11 defines general testing requirements and environmental conditions for electricity metering equipment, while IEC62053-21 specifies particular performance standards for Class 1 and Class 2 static (electronic) active energy meters.
Q5: Can this submeter be used for tenant electricity billing in commercial buildings?
A: Yes, building management frequently installs the DTS-238 as an internal submeter to accurately calculate and bill individual tenant power consumption.
Q6: How does a digital kWh meter compare to an analog electromechanical meter?
A: Digital kWh meters provide higher precision, feature no moving mechanical parts subject to wear, resist magnetic tampering better, offer clearer LCD displays, and consume less baseline power than traditional analog meters.
Q7: Who should install the DTS-238 3-phase kWh meter?
A: Installation should be carried out by a qualified electrician certified by Suruhanjaya Tenaga (ST) to ensure proper phase rotation, wiring safety, and compliance with local installation standards.
