FAQ
The DJSF1352-D-360 has a maximum measuring current of 360A with direct connection, complying with GB/T 33708-2017 standard.
In the menu, go to “IN” -> “NEg.U” or “NEg.I” and set it to “on”. If not set, the reading may appear negative.
It supports Modbus-RTU, DL/T 645-2007, and DL/T 698 protocols. Default baud rate 9600, no parity, 1 stop bit.
Set it in the menu “SYS” -> “PULS”. The pulse constant range for DJSF1352-D-360 is 1-300 imp/kWh, configurable according to actual requirements.
Connect via RJ12 interface. Supports 1 display module + 1 energy meter, or 1 display module + 2 energy meters. See section 4.4 of the manual for wiring diagrams.
Yes. The meter operates at -40℃ to +70℃, storage -40℃ to +70℃, humidity ≤95% non-condensing, suitable for outdoor cabinet installation.
Set it in the menu “bUS” -> “Addr”, range 1-247. Save and restart to take effect.
M2 terminal: 0.2N·m; M3 screw: 0.5N·m; M10 screw: 25N·m. Use a torque wrench to tighten according to specifications.
Line loss energy is the energy lost in the lines; lossless energy is the net energy after deducting line losses. The sum of the two equals the total energy.
Press and hold the confirm button on any display screen to enter the “PASS” interface. Enter the password (default 0001) to access parameter settings. Press and hold the confirm button to save and exit after configuration.
Summary
Tailored for the Chinese market, this meter offers high-current direct measurement with national standard compliance. Robust design, wide temperature range, and optional display make it a cost-effective choice for reliable DC charging pile energy monitoring.
