Product catalog summary

Product Overview: The DN3PW is a 3-phase voltage monitoring device designed to control the power supply network of a plant. It features adjustable reaction times and is housed in a 22.5mm casing suitable for DIN rail mounting.

Specifications: The device operates at 24V DC with a power consumption of 2.4W. It can handle input voltages ranging from 200V AC to 550V AC and has a maximum current of 0.2 mA per phase at 600V AC. The output contacts can switch up to 1A at 24V DC, with a minimum switch current of 10mA. The device is protected by a 5A fuse and can handle up to 360 switching cycles per hour.

Safety and Installation: Installation and operation should be performed by qualified personnel familiar with safety regulations. The device must be mounted in a closed cabinet to prevent moisture and dust interference, adhering to VDE 0106 part 100 specifications. It should be disposed of properly at the end of its service life.

Functionality: The DN3PW monitors the voltage of three phases and indicates their status via LED indicators. If all phases are present, the output relay contacts close after a 3-second delay. If a phase is missing, the LEDs flash, and the outputs remain off for at least 500ms even if the phase returns. The reaction time can be adjusted between 10ms and 100ms using an internal switch.

Environmental Conditions: The device operates within a temperature range of -10 to +60°C and can be stored between -40 to +85°C. It is vibration resistant and requires installation in a cabinet with at least IP 54 protection class.

Compliance: The DN3PW complies with DIN EN ISO 9001:2000 quality management standards and meets various safety and electromagnetic compatibility regulations, including EN 60068-2-6 and DIN EN 60947-5-1.

Product information Adjustment of the tolerance of the measurement voltage The voltage tolerance will be adjusted in the unit. This is possible via the blue switch inside the unit. There are 16 switch positions. Voltage fluctuations of one or more phases within the tolerance cause no switch-off of the outputs. Voltage fluctuations of one or more phases out of the tolerance cause switch-off of the outputs. Look at table. Important notice: After the switch-on of the power supply the equipment learns the actual measurement voltage of the phases. This act will be repeated every 6s. Please avoid to...
