MultiBox III
The MultiBox III is a fifth generation ventilation control unit based on the latest microprocessor technology.
It sends service messages and define the startup time and output voltage. More opportunities in one box and easy to use.
MultiBox III can be used for pressure measurement, control, regulation, and monitoring of alarm systems for process ventilation in the pressure range from 10 to 5000 Pa.
MultiBox III is especially useful for dynamic pressure regulation in installations with throttle valve and/or a fan with frequency inverter.
The desired pressure or flow (pressure difference) is encoded as a fixed point. The built-in regulator will adjust the damper or frequency converter. The alarm is activated if the regulation does not hold pressure/flow within the selected alarm limits.
- Speed regulation of fan with frequency inverter through an analog 0 to 10V DC signal
- Control of 24V motor damper
- On/off control of 24V motor damper
- Monitoring of pressure/flow with acoustic and visual alarm
- Pressure measurement with 2-line 16-digit display showing the current pressure in pascal
- Built-in pressure transducer for the range from 10 to 5000 Pa.
- 230V connection
