Acrel Launches Compact 36 mm DIN‑rail DC Energy Meter DJSF1352‑RN‑2 for DC Charging Pile Cabinet Integration

Release Date：September 3, 2026

As DC fast‑charging piles continue toward miniaturization and high‑density cabinet layout, internal installation space becomes increasingly precious. Traditional DC energy meters often occupy large cabinet space, bringing layout difficulties for compact‑size DC charging stations. To solve this pain point for charger manufacturers and system integrators, Acrel releases the new DJSF1352‑RN‑2 DIN‑rail DC energy meter, with ultra‑narrow 36 mm width, specially optimized for inner‑cabinet metering of compact DC charging piles.

Designed for direct DIN‑rail mounting inside DC charging cabinets, the DJSF1352‑RN‑2 only takes up 36 mm cabinet width. Compared with conventional large‑size DC meters, it greatly saves valuable internal space, leaving more room for power modules, circuit breakers and other components, making cabinet wiring and overall mechanical layout much easier, which is highly suitable for new‑generation small‑volume integrated DC charging piles.

Despite its compact body, the meter keeps complete measuring capability and high‑class accuracy. It supports comprehensive DC parameters measurement: DC voltage, DC current, active power and DC energy. With 0.5‑class high measurement accuracy, it guarantees reliable energy billing data for charging operators. Built‑in RS485 communication interface enables seamless data upload to charging pile controller or cloud management platform, supporting real‑time data acquisition, energy statistics and operation monitoring. The product has obtained CE certification, satisfying requirements for export to European and many overseas markets.

Core Product Highlights

Ultra‑narrow 36 mm DIN‑rail width: Perfect match for compact DC charging pile cabinet, greatly reducing space occupation.
Full‑parameter DC measurement: Voltage, current, power and DC energy all covered.
0.5‑level high precision: Stable metering performance for charging settlement scenarios.
RS485 Modbus‑RTU communication: Convenient to connect with pile main‑control unit and monitoring system.
CE certified: Compliant with overseas market access requirements.
Direct DIN‑rail installation: Fast on‑site assembly, simple wiring.

Application Case

One European DC charger OEM adopted DJSF1352‑RN‑2 for its new‑model 60kW compact DC charging pile. Thanks to the 36 mm narrow‑body design, the manufacturer successfully optimized the internal cabinet layout without enlarging the overall cabinet dimension. The meter reliably completes DC energy metering and transmits measuring data to pile controller via RS485, realizing accurate charging billing, and helps the product pass related CE compliance test smoothly.

“Small footprint without losing metering performance.” The compact DJSF1352‑RN‑2 provides a space‑saving metering solution for modern miniaturized DC charging equipment, helping charger manufacturers simplify mechanical structure design and accelerate product iteration for global markets.
