DJSF1352-D: High-Precision DC Energy Meter for EV Charging Applications

DJSF1352-D is a DIN35mm rail-mounted DC energy meter developed by Acrel for DC charging piles, photovoltaic storage systems, and industrial DC distribution. It integrates a high-precision shunt into the meter body, eliminating the need for external shunts and reducing installation complexity. The meter supports direct measurement of DC voltage (0-1000V), current (360A/600A), power, and energy, with accuracy up to Class B (Class 1.0). Its compact design (1/3-1/4 the size of traditional split-type meters) suits confined spaces like charging piles, while a wide operating temperature range (-40℃~+70℃) and high protection grade ensure reliability in harsh industrial or outdoor environments.

• Installation: Standard DIN35mm rail mounting for flexible deployment.
• Electrical Parameters: Voltage input 0-1000V DC; current measurement up to 600A (via internal shunt), overload capacity 1.2 times continuous operation.
• Accuracy: Class B (Class 1.0) for precise energy metering.
• Communication: RS485 interface supporting Modbus-RTU (default baud rate 9600, adjustable to 1200/2400/4800) and DL/T 645-2007 protocols for seamless integration with energy management systems.
• Display & Functionality: LCD screen for real-time display of voltage, current, power, and energy; supports parameter cycling and pulse output for remote meter reading.

Typical Applications
The meter is widely used in DC charging piles (for accurate energy consumption tracking and operational optimization), photovoltaic storage systems (to monitor generation and storage efficiency), and industrial DC distribution networks (to prevent equipment overload and reduce energy waste). Its robust protection (3.5kV/1min insulation withstand voltage) and anti-interference design make it suitable for harsh environments like factories, logistics parks, and outdoor charging stations

• Wiring: Use shielded twisted-pair cables for RS485 communication (each core ≥0.5mm²), with the shield grounded and cables routed away from strong power lines to avoid interference.
• Terminal Screws: Tighten screws to a maximum torque of 0.5Nm (3.5Lb-In) to prevent damage to the meter body.
• Commissioning: Switch display interfaces via buttons to view different parameters; configure communication protocols and baud rates according to system requirements.
