| Keterangan: | 96x96mm PowerLogic power-monitoring units for HV and LV networks :
* The PowerLogic Series 800 Power Meters offer high-performance measurement capabilities needed to monitor an electrical installation in a compact 96 x 96 mm unit. The power meter' s large easy-to-read display lets you view all three phases and neutral at the same time.
* Standard features of the PM800 series power meters include an RS485 Modbus communication port ( ASCII and RTU) , digital input, digital output, THD metering, and alarming. Also, the PM820, PM850 offer custom on-board logging and individual current and voltage harmonic readings. The PM850 offers waveform capture. And the PM870 is the first compact meter to offer voltage and current disturbance ( sag and swell) detection and configurable waveform capture.
Characteristics:
* Easy to install. Panel-mount with only two clips, or DIN rail mounting with or without remote display.
* Direct connect voltage inputs. No need for potential transformers ( PTs) up to 600 VAC
* Intuitive navigation with self-guided, language-selectable menus
* Large, anti-glare display with white back-light provides summary screens with multiple values
* Custom alarming with time stamping
* Individual harmonic magnitudes and angles, and waveform capture ( PM850 and PM870)
* Voltage and current disturbance ( sag and swells) detection and configurable waveform capture ( PM870)
* Extensive and non-volatile On-board memory
* IEC 62053-22 class 0.5S for real energy. Accurate energy measurement for sub-billing and cost allocation
* Trend curves and short-term forecasting ( PM850 and PM870)
* Five channels of WAGES ( water, air, gas, electricity, steam) metering capability on all models. A single channel can aggregate pulses from multiple inputs.
* Modular and upgradeable
* Optional Remote Display ( as far as 10m from the metering unit)
* Optional Ethernet communication port offers Modbus TCP/ IP protocol, e-mail on alarm, web server and Ethernet-to-serial gateway. Transparent Ready – Level 1 compliant.
Benefits
The PowerLogic Series 800 Power Meter is designed to:
* Reduce energy costs by helping you understand where and how energy is being used
* Extend equipment life and avoid unnecessary equipment purchases by helping you understand circuit loading and identify spare capacity
* Improve power system reliability and reduce downtime by helping you monitor, troubleshoot, and prevent power quality issues ( the PM870 includes sag and swell detection and configurable waveform capture)
* Measure and manage non-electric utilities using up to five different channelsfor optimal management of your electrical installation and a better productivity.
Applications
* Panel instrumentation
* Sub-billing, cost allocation, and utility bill verification
* Remote monitoring of an electrical installation.
* Mid-range power quality and energy management analysis
* Utility contract optimisation and load preservation |
