ACREL DIN Rail Mounted DC Power and Energy Meter 1000V
ACREL DIN Rail Mounted DC Power and Energy Meter 1000V is a DIN-rail mounted DC power meter for measuring voltage, current, power and energy in DC systems. It supports DC voltage inputs up to 1000 V and current measurement using 0-75 mV shunts or compatible Hall sensor signal inputs. RS485 communication with Modbus-RTU and DL/T 645-2007 protocols provides access to measured data for monitoring and energy management systems.
DJSF1352-RN (Base/Standard): Uses a standard wide-range auxiliary power supply of AC/DC 85–265V.
DJSF1352-RN-P1: Uses a specific low-voltage DC auxiliary power supply of DC 24V (or 48V depending on configuration).
DJSF1352-RN-P2: Uses a specific low-voltage DC auxiliary power supply of DC 12V. (Note: Selecting the P2 auxiliary power option typically restricts current input compatibility to 0–75mV shunts rather than certain dual selections).
The ACREL DIN Rail Mounted DC Power and Energy Meter 1000V provides measurement and monitoring of key electrical parameters in DC power systems. The meter is designed with two DC input channels and can measure voltage, current, power and forward and reverse energy.
DC voltage can be measured from 0 to 1000 V, while current measurement can be configured for a 0-75 mV shunt or Hall sensor inputs including 0-20 mA, 4-20 mA, 0-5 V and 0-10 V. The manufacturer specifies Class 1 or Class 0.5 accuracy, depending on the configuration.
The meter provides an 8-bit segment LCD for local viewing and an RS485 communication interface. Supported communication protocols include Modbus-RTU and DL/T 645-2007, allowing measured information to be transferred to compatible monitoring or control systems.
The DJSF1352-RN is installed on a 35 mm DIN rail and is suitable for applications including DC battery systems, charging piles, solar photovoltaic systems and telecommunications base stations.
