Product Introduction

ETCR8340 Multichannel Current & Voltage Online Tester is used for on-site online real-time monitoring and recording of multi-channel AC current and AC voltage.Troubleshooting circuit insulation faults, monitoring intermittent leakage faults, transformer core grounding current monitoring, cable grounding circulation monitoring and other line current and voltage monitoring.The tester is composed of a collector module, an open transformer, etc.The collector module can be connected to 3 current transformers and 3 voltages.The collector module has an RS485 interface and provides a MODBUS communication protocol to facilitate users' secondary development.The transformer has a variety of styles such as round, flat mouth, and waterproof type for users to choose from. The open structure eliminates the need for power outages and disconnects the cables during on-site installation, which is convenient and safe to install.It can be widely used in the online monitoring of AC current, ground circulation, and AC voltage of electrical installations, and provides safe, accurate, and convenient power testing instruments for power inspectors.
1. Provide current transformers and PCB conditioning boards to facilitate users to develop online monitoring systems for the second time, and background systems can also be developed according to user requirements.
2. Monitor the current and voltage of multiple loops online at the same time, and the number of loops can be customized according to user requirements.
3. For different application scenarios, a variety of current transformers are provided for users to choose from, and the range can be customized according to user requirements.
4. It can meet the wide voltage power supply of 6~24V.
5. The LCD screen can be configured to view the current AC current value or AC voltage value on site.
6. Provide RS485 communication, users can carry out secondary development, form a network, and realize remote multi-point online monitoring according to the MODBUS communication protocol.
