DCPM Multi-channels Isolated DC Meter, a new design din-rail mounting DC metering device, provides standard 8 channels, max 24 channels isolated measurement, and collects DC circuit basic parameter value (Volt, Amp, Power, Energy consumption & generate). Besides, it uses high-speed isolation devices to isolate the signals of each channel. This DC voltage monitor uses an RS485 MODBUS line to send data to the site server or remote SCADA. Besides, it uses high-speed isolation devices to isolate the signals of each channel.
The DCPM multi-circuit dc energy meter is an extremely low data refresh interval (20ms per cycle), suited for field devices’ power circuit condition monitoring such as Solar plant and Telecom server room, BMS applications in UPS systems, etc.
Overview
The DCPM Series DC Meter includes DCPM and DCPM-24. The DCPM is an 8-channel DC meter while the DCPM-24 is a 24-channel DC meter. The access of them is Directly access or external CT. The dimension is 120*110.5*50mm.
Feature of DCPM series DC Meter
- Din-rail mounting design & compact size
- Current signal: Directly input default 10ADC (Optional 1mA, 20mA, 100mA, 1A/5A) Voltage signal: 100-600V
- 8 channels metering loop, each metering channel is isolated
- 8-channel or 24-channel DC voltage and current measurement, capable of universal AC and DC measurements;
- Seven acquisition speeds are adjustable, that is, all electrical parameters can be measured within a set time;
- High reliability, each channel is isolated from each other, the power supply, communication, and the terminal under test are fully isolated, and the withstand voltage is greater than 2500V;
- There are two options for setting address and baud rate using hardware DIP switch and software setting.
- Provide DC voltage, current, power, and energy value in one
- Record energy value in absolute value or signed value
- Support OEM & ODM service
