The AcuDC 240 Series measures DC voltage, bidirectional current, power and energy for DC distribution, renewable-energy and industrial systems. The current AcuDC 243 ordering model supports direct or externally sensed inputs, optional I/O, RS485 communications and data logging. Full-scale primary current depends on the selected shunt or Hall-effect sensor.
Accuracy:
Voltage/current 0.2%; active energy 0.5%
Current:
A0: ±10 A direct; A1: 50-100 mV shunt; A2/A3: Hall sensor input
Communication interface:
Optional RS485 Modbus RTU and data logging
Operating Temperature:
-25 to +70°C
Input:
0-1000 VDC direct; external Hall voltage sensor for other ranges/isolation
Power Supply:
P1: 100-240 VAC / 100-300 VDC; P2: 20-60 VDC
Output(s):
Optional 2DI with analog, relay or digital output packages
Storage Temperature:
-40 to +85°C
Current ordering documentation lists AcuDC 243. Older model choices absent from that sheet require availability confirmation. With current Hall-effect input and direct voltage input, only negative-grounded systems are supported. Positive-grounded, ungrounded or center-tap systems require an external voltage Hall-effect sensor. Current and voltage sensors are selected separately.
Availability: Inquire. Confirm the selected configuration and delivery with Mod-Tronic.
AcuDC 241 and 242 appear in older supplier manuals, but the current ordering sheet lists AcuDC 243. Confirm availability of older models. The EV-charger -U configuration and separately selected shunt ratings are available by project-specific inquiry.
