The QOLTEC Single Phase Energy Consumption Meter 100A is compared with two alternative devices: the Three-phase analog energy meter EM-10 and the smart QOLTEC Wi-Fi Electricity Meter with Relay, 63A, DIN Rail Mount, Timer, Tuya App Support. All these devices are designed for measuring and monitoring electrical power consumption in residential or commercial settings, but they differ significantly in electrical system compatibility, current capacity, display methods, and smart management features.
⚙️ The specifications and key differences compared below include electrical system type, maximum current load, data display interface, and remote control capabilities.
| Comparison parameter | QOLTEC Single Phase 100A | Three-phase analog EM-10 | QOLTEC Wi-Fi 63A | Practical significance |
|---|
| System type | Single-phase | Three-phase | Single-phase | The main model is built strictly for single-phase networks, whereas EM-10 is engineered for three-phase systems. |
| Maximum current | 100A | Standard industrial capacity | 63A | The main model supports a higher maximum current load compared to the 63A smart variant. |
| Display type | Digital monitoring | Analog display | Tuya app integration | EM-10 relies on a traditional analog readout, while the smart QOLTEC version enables remote monitoring via mobile app. |
| Additional features | Energy consumption monitoring | Basic energy tracking | Relay, timer, DIN rail mount | The smart version introduces automation and remote power scheduling absent in standard analog and single-phase meters. |
◎ The evaluation of use cases and buyer profiles below will help determine which device best aligns with your energy monitoring requirements.
| Use case | Recommended product | Why |
|---|
| High-load single-phase energy monitoring | QOLTEC Single Phase Energy Consumption Meter 100A | Rated for up to 100A, this device is well-suited for heavy-duty single-phase residential or commercial lines. |
| Three-phase electrical system tracking | Three-phase analog energy meter EM-10 | Specifically built for three-phase power systems featuring a reliable analog display. |
| Smart home automation and remote control | QOLTEC Wi-Fi Electricity Meter with Relay, 63A, DIN Rail Mount, Timer, Tuya App Support | Includes an integrated relay, timer, and Tuya app support for remote scheduling and power management. |
QOLTEC Single Phase Energy Consumption Meter 100A is ideal for users who need precise energy tracking on a high-capacity single-phase line without requiring smart remote management. If you operate within a three-phase system, the EM-10 is the appropriate choice, while smart home automation needs are best met by the Wi-Fi-enabled QOLTEC alternative.
