Product Description

Product Description

DJSF1352-RN Din Rail DC Power Meter

General
DJSF1352-RN din rail DC power meter with dual channel DC input is suitable for telecommnications base stations,dc chargingpiles,solar pv and other applications.It can measure voltage,current,power,forward and reverse energy and so on in DC system.Itcan also measure total power and energy within a period of time.
The meter have infrared communication interface and RS-485 communication interface, and supports Modbus-RTU protocol andDLT645-97 (07) protocol at the same time. The meter can have relay alarm output and digital input function; You can set the ratio,alarm, and communication through the meter panel keys according to different requirements. The meter can have event recording ofswitch (Modbus protocol), programming and event setting records (645 protocol), instantaneous and timing freeze function of data(645 protocol), maximum and minimum value recording function of voltage and current power.
