Feature:

Function	Measuring range		Starting current/power		Resolution	Measurement accuracy	Display format
	10A	100A	10A	100A
Voltage	80-260V				0.1V	0.5%
Current	0-10A	0-100A	0.01A	0.02A	0.001A	0.5%	<1000W displays 1 decimal place, such as: 999.9W; >=1000W, only displays integers, such as: 1000W
Active power	0-2.3KW	0-23KW	0.4KW		0.1W	1%
Power factor	0.00-1.00				0.01	1%
Frequency	45HZ-65HZ				0.1HZ	0.5%
Active energy (power clear, software clear)	0-9999.99KWH				1WH	0.5%	<10kWh, the display unit is Wh (1kWh=1000 Wh), such as: 9999Wh; >=10kWh, display unit is kWh, such as: 9999.99kWh
Power overrun alarm	The active power threshold can be set, and the alarm state is set when the measured active power exceeds the set threshold.
Communication Interface	TTL interface
Power supply	The single-phase power frequency grid power supply is supplied to the main circuit through the RC capacitor, and the TTL output communication interface is isolated from the main circuit optocoupler and is a passive output. An external 5V power supply is required for communication.
Note	The TTL interface of this module is a passive interface. It must be externally supplied with 5V power supply. That is, all four ports must be connected (5V, RX, TX, GND) during communication, otherwise communication cannot be performed.
Operating temperature	-20°C~+60°C

Package includes:

1 x TTL Serial Communication Module
