FAQ
Yes, this model has passed EU MID certification, Certificate No.: 0598/MID/B/25/003, compliant with EN 50470-4 standard, suitable for billing purposes in the European market.
The DJSF1352-D-600 has a maximum measuring current of 600A with direct connection, complying with EN 50470-4 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.
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
With MID approval, this meter is suitable for billing applications in the European market. High-current direct connection, wide temperature range, and flexible display options ensure reliable and compliant energy measurement for EV charging stations.
