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.
