The DJSF1352-D is a DIN-rail DC energy meter built for photovoltaic, energy-storage, EV-charging and DC-distribution circuits. It measures up to DC 1000 V through a built-in shunt, so the current path needs no external CT and no extra wiring in the pile.
What it measures
| Parameter | DJSF1352-D |
|---|---|
| Voltage input | DC 0-1000 V |
| Current input | 100(360) A per GB/T 33708-2017, or 4-90(600) A per EN 50470-4 |
| Accuracy class | 0.5 class (class C) on the -360; 1 class (class B) on the -600 |
| Energy direction | Bidirectional active energy, for charge and discharge accounting |
| Measurement | DC voltage, current, power and energy |
| Display | Segment LCD |
| Communication | 1 x RS485; Modbus-RTU, DL/T 645-2007 and DL/T 698, baud 1200-38400 bps |
| Pulse output | One energy pulse; constant set in SYS to PLUS (100 = 100 imp/kWh) |
| Auxiliary supply | DC 9-36 V, 3 W or less |
| Case | -360: 124.6 x 59.4 x 50 mm; -600: 105 x 115 x 65 mm |
| Environment | -40 to +70 C, 95% RH or less non-condensing, up to 2000 m |
Where it saves space in a charging pile
- The shunt is inside the meter, so a compact pile deletes one external component and its terminations.
- DIN-rail mounting drops into an existing 35 mm rail next to the controller.
- Protocol auto-adaptation means the same unit talks Modbus-RTU to a controller or DL/T 645 to a revenue-checking device.
- The energy pulse output gives a second, independent register for factory acceptance.
- Operating range down to -40 C covers outdoor installations in cold storage and northern climates.
Metering for EV non-onboard chargers follows GB/T 29318-2012; the -360 and -600 models are built to different reference standards, which is why their accuracy class differs.
Inside the pile the meter sits on the DC side between the converter and the contactor: the DC bus and the built-in shunt feed the voltage and current inputs, the RS485 port runs to the pile controller, and the energy pulse output can feed a second checking device. The meter itself is powered from a DC 9-36 V supply.
What to tell us before we quote
Send the DC bus voltage, the maximum and minimum charging current, the auxiliary supply available inside the pile, and the protocol your controller expects. We confirm the model suffix, the shunt rating, the wiring diagram and the register map, and return the ordering code within one working day.
