Metering Features
EV300 Series power meter offers robust metering capabilities at a great value
Universal Rating Meter
Voltage: Measuring from 10V to 400Vac direction that works with any voltage rating system. Potential Transformer ratio configuration supported.
Current: 5A and 1A CT input field-configurable that suits any industrial current transformer.
Frequency: Automatically adapt to 50Hz and 60Hz system without compromising the accuracy, which simplify design and eliminate international OEM frequency issues.
Multiple I/O Built-in
Digital Input: Monitor switch status, directly display on front LCD display and remotely accessed by communication.
Built-in Power Supply: 24Vdc provides direct power supply to digital input. It reduce the cost, complication and space limitation of additional low voltage power supply in panel.
Digital Output: Pulse output provides energy data to any data acquisition server.
Analog Output: 4-20mA transducer type analog output can be interfaced with any PLC directly.
Relay Output: Over/under limit alarm triggered relay output to control load on/off for load shedding.
