Frequently Asked Questions - Digalox DPM72-MPN+-DIN TDE Instruments
What is the Digalox DPM72-MPN+-DIN used for?
It is a multifunction energy meter for measuring electrical parameters like voltage, current, power, and energy in industrial or commercial installations.
How do I install the meter?
Mount it in a 68x68 mm panel cutout, secure with the provided brackets, and connect wires per the wiring diagram in the manual. Use external current transformers (CTs) as required.
What is the power supply requirement?
The meter requires 230 V AC (50/60 Hz) for the auxiliary supply. Alternatively, a DC option may be available; check the model label.
Can I connect it directly to high voltage?
The voltage inputs accept up to 500 V AC directly (L-L). For higher voltages, use potential transformers (PTs). Always follow local safety regulations.
How do I read the energy consumption?
The display shows cumulative active energy (kWh). Press the button to scroll through other parameters like reactive energy, instantaneous power, etc.
What communication protocols does it support?
It features Modbus RTU over RS485 for remote monitoring and a pulse output for energy pulsing. Baud rate and address are configurable.
How do I reset the energy counters?
To reset partial counters, hold the button for 5 seconds. Full cumulative counters cannot be reset; they are factory-calibrated.
What should I do if the display is blank?
Check the auxiliary power supply (L/N terminals) and ensure the voltage is present. If still blank, measure the backup fuse (if any). Contact support if needed.
How do I clean the meter?
Wipe the front panel with a dry, soft cloth. Do not use solvents or water. Keep ventilation slots unobstructed.
Where can I find spare parts or accessories?
Contact TDE Instruments or an authorized distributor for replacement terminal covers, fuses, CTs, or the optional Modbus adapter.
