IC660BPM100 电源监控模块

Accurately measures the RMS values of voltage, current, power, VARs, power factor, and watthours, even with distorted waveforms.

Measures line frequency.

Detects and captures overcurrent waveforms above a configurable current level.

Indicates magnitude of system harmonic content.

For both wye (4-wire) and delta (3-wire) systems.

Simple user connections.

Direct connection for up to three potential transformers and three line current transformers plus one neutral current transformer.

Low current transformer burden (less than 0.1VA).

Software configurable, including scaling.

Small size and rugged design for mounting in electrical distribution and process equipment.

Integral power supply accepts either 115/230 VAC or 125 VDC inputs.

Can be installed on bus up to 7500 feet from host.

Compatible with CPU redundancy configurations.

Can be used for stand-alone monitoring without a host.
The Power Monitoring Block (IC66*BPM100) monitors current and voltage inputs and stores digitized waveform values for each input. From these values, the block calculates RMS values of voltage, current, active power, reactive power, KWH, and power factor. Frequency is also measured. The block automatically sends this calculated data to a programmable controller or host computer
approximately twice per second. The same data can be displayed on a Hand-held Monitor from any location on the bus.
If an overcurrent transient exceeds a configurable level, the block captures the resulting waveform. A simple measure of system harmonic content indicates the extent to which this problem exists. The block will supply waveform data to the PLC or computer, for harmonic or transient analysis, upon request.

The block can be used with a wye or delta configured three-phase power system or with a single-phase power system. It accepts voltage inputs from as many as three potential transformers, and current inputs from one to three line current transformers, plus a neutral current transformer.
The turns ratios of both current transformers and potential transformers are software-configurable.
Current transformers with a secondary rating of up to 5 amps and primary ratings up to 3275 amps for line connections or 325 amps for auxiliary (neutral) connections may be used. Potential transformers with a secondary rating up to 120VAC (47–63 Hz) and primary ratings up to 327KV may be used, with line-to-line or line-to neutral connections
