Product Features

The EX2-ZL DC power monitoring instrument is a new generation of panel mounted miniature energy meters developed by Shandong Lichuang Technology Co., Ltd. based on years of experience in energy metering product design. This energy meter adopts LCD display, which can display voltage, current, power, forward energy, reverse energy, communication address, communication verification method, communication baud rate, voltage conversion ratio, current conversion ratio and other parameters, and has the function of outputting electrical energy photoelectric pulses; RS485 communication interface can be used to exchange data with the upper computer, supporting MODBUS-RTU protocol, which greatly facilitates power automation management.
This electric energy meter has the advantages of small size, easy installation, high accuracy, and good EMC performance.

PRODUCT FUNCTION

7-bit wide temperature LCD display
◆ Can achieve data loop display, with a loop display time of 2 seconds
◆ Equipped with an electrical pulse output interface and a red LED indicator
The button can be used to set the verification method, baud rate, voltage ratio, and current ratio
Communication interface: RS485 (optical isolation)
Communication protocol: MODBUS-RTU
Communication speed: 1200bps, 2400bps, 4800bps, 9600bps can be set.

PRODUCT FUNCTION

performance			parameter
Losing enter measure measure apparent show	electricity press	measuring range	Directly connect to -48V (± 10%), and when measuring a larger range, a voltage divider device can be used and the voltage transformation ratio can be changed. The maximum range of indirect intervention is 500V
		transformation ratio	1-500，Uo×Ubb<500V
		accuracy	RMS measurement (voltage accuracy:0.5Grade)
	electricity flow	range	Indirect access 0-75mV, corresponding to 0-1A, the range can be expanded by changing the current ratio, indirectly connecting to a maximum measurement of 1000A
		transformation ratio	1-1000，Io×Ibb<1000A
		accuracy	RMS measurement (current accuracy:0.5Grade)
	forward power		Active accuracy: Level 1; Maximum measurement up to 500kW
	reverse power		Used to indicate the wiring direction of the splitter. If the splitter is connected in reverse, the module will display the reverse power
Electricity Can Testing Quantity	Positive electrical energy		Accuracy: Level 1. When (Uo × Io × Ubb × Ibb)>=2515, the maximum measurement reaches 999999 kWh and then resets to zero; When<2515, the maximum measured kWh is (397.682 × Uo × Io × Ubb × Ibb), and it automatically resets to zero when the maximum value is reached.
	Reverse electrical energy		Used to indicate the wiring direction of the splitter, the splitter is connected in reverse, and the module accumulates reverse electrical energy
electricity source	power supply		Internal power supply
	power consumption		<3W
transport go out approve weave Cheng	open up or clear out by poking or jabbing interrogate	output interface	RS-485 interface, two-wire system+ 15kV ESD protection
		Communication Protocol	Standard MODBUS-RTU communication protocol
		data format	Can be set; 10 bits, 1 start bit 0, 8 data bits, 1 stop bit 1; Or 11 bits, which can be set by software for odd, even, or no verification;
		COMMUNICATION RATE	BPS： 1200, 2400, 4800, 9600 can be set
	display		LCD segment code display
	Electric pulse output		Optical signal output
ring area	work environment		Working temperature:-15～50℃
	storage environment		Storage temperature:-20～60℃
	relative humidity		Relative humidity ≤ 90%No condensation
peaceful complete	pressure resistance		Input and output>1kV
	isolation		Output, input, and power supply to casing>5M
