Function
| Dual Measurement | Simultaneously measures cable temperature and current. |
| Dual Power Supply | Powered by internal battery (CR2450) or electromagnetic energy from the cable (CT-powered). When current ≥2.5A, sensor switches to CT-powered mode, saving battery. |
| Wireless Communication | Transmits data via 470MHz or 433MHz frequency to a receiver (e.g., ATC600-C). |
| Configurable Sampling Cycle | CT-powered: 10~30 seconds; Battery-powered: 3 minutes. |
| Status Indicator | LED flashes to indicate data transmission. |
| Easy Installation | Open snap-type clamp for quick mounting on cables. |

Summary
The ACE100-29 wireless temperature & current sensor provides a reliable and cost-effective solution for monitoring low-voltage cables in switchgear and distribution cabinets. By combining temperature and current measurement in one device, it reduces installation complexity and cost. The dual-power design ensures long-term operation with minimal maintenance, while wireless transmission enables easy integration into existing monitoring systems. Paired with the ATC600-C receiver and ATP series touchscreens, it forms a complete cable condition monitoring solution.
FAQ
No. ACE100-29 is designed specifically for low-voltage applications (0.4kV). For medium/high-voltage cables, please refer to our ATE series sensors with appropriate insulation.
The sensor requires at least 2.5A AC to start energy harvesting. Below that, it runs on battery.
Approximately 3 years at 25℃. When the battery is low, the sensor can still operate if current is above 2.5A.
The sampling cycle is fixed: 10~30s when CT-powered, 3 minutes on battery. This optimizes battery life and data freshness.
The LED flashes each time data is transmitted. You can also check received data on the monitoring system.
ACE100-29 works with ATC600-C receiver. One ATC600-C can receive up to 240 sensors.
