品牌：美国 OSI

型号：DW5

类型：交流瓦特传感器（DIN导轨式交流功率传感器）

产品说明/DESCRIPTION

DW5型在单相或多相系统中提供的功率测量精度在满量程精度的±0.5%以内。电隔离直流输出与几个周期内平均的瞬时功率成比例，DW5封装在DIN导轨箱中，便于安装。

高达5安培的电流和高达600Vac的电压可直接连接到DW5，DW5可与OSI计量级电流互感器一起使用，用于测量高达10千安培的电流。

可以选择特定的输出与任何数据采集系统接口，从简单的记录器到基于计算机、SCADA或PLC的系统。

DW5广泛应用于各种应用，包括水轮发电机输出测量、能源消耗终端设备测试、楼宇自动化、能源管理和热电联产系统。它具有CE和CSA认证，并根据ISO-9001进行制造和测试。

The Model DW5 provides power measurement to within ±0.5% of full-scale accuracy in single- or polyphase systems. The electrically-isolated dc output is proportional to the instantaneous power averaged over several cycles. The DW5 is packaged in a DIN-Rail case for easy installation.

Currents up to 5 Amperes and voltages up to 600Vac can be directly connected to the DW5. The DW5 can be used with OSI metering class current transformers for measurements up to 10 kiloamperes.

Specifi c outputs can be selected to interface with any data acquisition system from a simple recorder to computer-, SCADA-, or PLC-based system.

The DW5 is widely used in a variety of applications, including hydroelectric generator output measurement, end-of-line appliance testing for energy consumption, building automation, energy management, and cogeneration systems. It comes with CE and CSA approvals and is manufactured and tested in accordance with ISO-9001.
