品牌：美国 OSI

型号：DVT

类型：单相交流电压传感器

产品描述/DESCRIPTION

DVT型传感器提供与施加电压成比例的电气隔离输出。传感器输出由输入的算术平均值导出，并校准为正弦波输入的RMS值。传感器符合有关EMC和安全（IEC 1010）的要求和法规，其设计根据ISO 9001制造和测试。

The DVT model transducers provide an electricallyisolated output which is proportional to the applied voltage.Transducer output is derived from the arithmetic mean value of the input and calibrated as the RMS value of a sine wave input.The transducer fulfi lls requirements and regulations regarding EMC and safety (IEC 1010) and was designed,manufactured and tested in accordance with ISO 9001.

安装说明/INSTALLATION INSTRUCTIONS

1.只能由合格的电工进行安装！

2.在进行任何电气连接之前，确保电气服务已断开。

3.支路保护按国家和地方规范要求设置检查机构的报告。

4.按要求布线，并按照本表和装置上的接线图固定到端子上。

5.传感器适合安装在600Vac线路上。

6.为防止与带电电路接触，当安装在裸母线上时，要求传感器安装在需要使用工具进入的外壳中。当安装在绝缘电缆上时不需要第二个外壳的电缆。

1. Installation should be performed by qualifi ed electricians only!

2. Make sure electrical service is disconnected before making any electrical connections.

3. Branch circuit protection is required to be provided in accordance with the National and Local codes of the inspection authority.

4. Route wires as required and secure to terminals per connection diagram on this sheet and on the unit.

5. Transducers are suitable for installation on 600Vac lines.

6. To prevent contact with live circuits, when installed on a bare bus bar, the transducer is required to be mounted in an enclosure that requires the use of a tool for access. When installed on an insulated cable this second enclosure is not required.
